This is a much easier process than the 'Copy Database Wizard' which has two procedures one of which is the same as the manual process but carried out under the guidance of a wizard and the other which does not require the stopping of the Source server. http://tc.eserver.org/30800.html http://tc.eserver.org/30800.html The article discusses the precaution thta one can take in installing the Microsoft SQL 2008 Sever (Developer Edition). Links to downloading a sample database with how-to note is also provided. Some of the initial problem solving in cleaning up the .NET miscellanea is discussed in this blog at : http://hodentek.blogspot.com/2008/01/you-were-cleaning-up-net-framework.html http://tc.eserver.org/30755.html http://tc.eserver.org/30755.html Explains how recent legislation and the effects of corporate scandals have necessitated greater due diligence on companies and individuals. Gives details of relevant existing and forthcoming legislation and discusses how a due diligence process can ensure compliance with the law. Points out that prospective clients, employees and investors may all require investigation, and then reviews some of the information sources available for use in both corporate and individual investigations. Considers the impact of international developments, particularly in the light of increased merger and acquisition activity, and discusses some of the barriers to acquiring effective due diligence. Finally considers the applicability of selected commercial databases. http://tc.eserver.org/30759.html http://tc.eserver.org/30759.html Case study describing the realignment of the Business Information Service (BIS) in ABN AMRO. Explains the reasons for change and the plans to incorporate the concept of continuous improvement, helping to ensure the service constantly evolves to meet demands of the organization. Includes a description of the bank and its operations and explains the role of the BIS within it. Explains how the service will be realigned to embrace the principles of continuous improvement, covering changes in both the Research and Support Services sections, and outlines how these changes will be achieved. Concludes that to make a difference, such change must be a constant. http://tc.eserver.org/30756.html http://tc.eserver.org/30756.html Interview with Greg Simidian, Managing Director of company information vendor Perfect Information. Discusses the company itself and how it has changed over the years, concentrating particularly on its customer relations. Considers relations between vendors and intermediaries generally, covering contract negotiation and the impact of end users, and also considering recruitment and skills issues for the information industry. Speculates on the future of the industry, considering social networking in particular. Reflects on Greg Simidian's previous career, considering the benefits of working for both mainstream and niche information providers. http://tc.eserver.org/30681.html http://tc.eserver.org/30681.html Exposing server data to intranet/internet, an attractive and much needed method has become possible due to the native web services, services that can be created on the database itself to which HTTP or Soap requests can be made. SQL Anywhere server, even in version 9.0 [present version SQL Anywhere 10] possessed this built-in capability of being able to expose data on the database server to HTTP requests. http://tc.eserver.org/30657.html http://tc.eserver.org/30657.html When your Web application reaches a certain size, it needs a good database design behind it. And in fact, this 'certain size' is much smaller than almost every small-site developer thinks. Relational Data Base Management Systems (RDBMSes) need not be restrictive or over-architected, as their bad reputation sometimes brings developers to fear. A bit of thought toward what your site does quickly turns into a sensible schema design, and it is easy to leave open expandable storage mechanisms like a configuration table within an RDBMS back end. http://tc.eserver.org/30653.html http://tc.eserver.org/30653.html Imagine controlling your customers' information, including how it is updated, managed, printed and distributed. Printers that provide database management services don't have to dream about such a scenario. http://tc.eserver.org/30648.html http://tc.eserver.org/30648.html Beginners Guide to SQL Server Integration Services Using Visual Studio 2005 provides you with the basic knowledge that you should have before you move on to more advanced ETL [Extraction, Transformation, and Loading]. The book will also provide you with a comprehensive description of the many designer windows that you may encounter while working with the designer. This guide provides the building blocks describing each block by way of an example as well as describing the nuts and bolts that bind the blocks. A majority of SSIS tasks are covered in this book and they are described fully in the summary of table contents section. You start building packages right from Chapter 2 and continue on to Chapter 20 gathering and building upon your knowledge in each step. http://tc.eserver.org/30610.html http://tc.eserver.org/30610.html The success of any technical document depends on the reliability of information presented in the document. A database can provide an informal mechanism for exchanging information about product development and support, The database system should have a user interface that is easy to use and does not require too many operations. Factors that must be addressed in the design, testing, and implementation of the database include the type of information, ownership, system maintenance, access control, and system development tools. Writers, who have special expertise in information gathering, can take the initiative and build support for the project. http://tc.eserver.org/30377.html http://tc.eserver.org/30377.html To perform complex tasks, workplace computer users have to know how to control their programs and adapt program capabilities to the needs of their job goals and methods. I inquired into the instructional information that will help users learn such adaptive computing for complex data processing tasks by interviewing twelve experienced database users and analyzing twenty-five exchanges between experts and users on a database helpline network. Findings show that instructions may help users emulate expert approaches to adaptive computing for complex tasks by providing enough substantial technical information to help clarify task problems, goals, methods and analogies and presenting it in the form of rules of thumb, general procedures, and task-to-program explanations. http://tc.eserver.org/30149.html http://tc.eserver.org/30149.html The results of a Motorola human resources survey revealed an inadequate procedure for selecting training programs pertinent to specific job functions and individual career aspirations. A cross-functional team was formed to remedy the situation within one division. The team selected skill and knowledge criteria for career paths (early, middle, and late) in specific technical disciplines, such as applications engineering, technical communications, applications support, etc. The new training database also includes training, book, and article evaluations that other employees can review. In addition, the database provides access to the Motorola University training catalog and the Motorola technical libraries. http://tc.eserver.org/30115.html http://tc.eserver.org/30115.html FileMaker 9 opens up ODBC data in a revolutionary way, via the new feature External SQL Data Source. You can work with external data in your FileMaker Pro solutions as if it is FileMaker Pro data. http://tc.eserver.org/30114.html http://tc.eserver.org/30114.html XML will change the way you develop and integrate your databases. http://tc.eserver.org/29929.html http://tc.eserver.org/29929.html Business needs often necessitate data migration from a smaller, less secure database to a higher end, faster database server with a more reliable availability. A typical scenario is the migration of data from a desktop sized database such as MS Access or Fox Pro to any other higher end database servers such as MS SQL Server, Oracle, DB2 or SQL Anywhere Server. Oracle SQL Developer 1.2 with this latest version is sometimes called the Migration version as it supports migrating data from three vendors (MySQL, SQL Server and MS Access) to an Oracle database. In fact, it has been designed to migrate from more than one version of MS Access. This feature was not available in the version 1.1 of this tool. http://tc.eserver.org/29628.html http://tc.eserver.org/29628.html Many technical communicators manage large collections of graphic files and must keep track of which graphics are used in which deliverables. An effective tool for managing a collection of graphic files is a relational database management system (RDMS) such as Microsoft Access. Before the database can be built in Access, it is necessary to 1) create detailed functional requirements and 2) build a high-level conceptual model from which the database relations (tables) can be derived. A spreadsheet program can be used to build the conceptual model and generate the relations. Normalization checks should be performed on the relations before the database is implemented in Access. http://tc.eserver.org/29447.html http://tc.eserver.org/29447.html This article by Jayaram Krishnswamy shows how you can install the Oracle SQL Developer 1.2 and connect to an MS Access database. This article will cover the steps right from downloading and installing the Oracle SQL Developer, to connecting to a MS Access database, and using the SQL interface along with a few sample queries. http://tc.eserver.org/29422.html http://tc.eserver.org/29422.html Work with your fellow employees to understand how they enter data so you can determine the best way to present their choices; they won't forget who's responsible for their improved accuracy and speed, particularly around performance appraisal time. Of course, you'll also earn your own manager's gratitude once you're no longer wasting time fixing preventable errors. http://tc.eserver.org/29299.html http://tc.eserver.org/29299.html This article by Jayaram Krishnswamy shows how you can develop a VB.NET 2.0 application using the integration features provided by the SQL Anywhere database. The SQL Anywhere tools are directly accessible without going out of the Visual Studio 2.O IDE. The article describes a window application with two examples developed with this easy to use integration interface. http://tc.eserver.org/28886.html http://tc.eserver.org/28886.html Software development and related IT services have boosted the Indian economy in the recent past. There are potential opportunities to provide innovative products and services. There are a large number of small and medium sized software development enterprises that are today in the market in response to demand. While most of them are engaged in software development services, there are a few organizations involved in software product development. Parallelly, Open Source Software (OSS) developers provide the complete source code of their software (libraries, APIs, device drivers and functional packages) free of charge. There is a great incentive for software product developers to use these available resources. However, all Open Source software is subject to specific terms of use or a license which is specified as part of the software. There is no catalogued repository of open source software that provides the licensing details as well as terms of reuse of the software. Software And Licensing Information System (SALIS) fills that void and attempts to provide details required by software product developers to make a decision on what software components can be used and built upon. http://tc.eserver.org/28877.html http://tc.eserver.org/28877.html Apart from implementing the right technology, libraries need a clear understanding of changing user requirements, the capabilities and limitations of emerging technologies, and the changing nature of scholarly communication. http://tc.eserver.org/28732.html http://tc.eserver.org/28732.html SQL Anywhere 10 database and Microsoft Word 2007 are the latest software from the respective companies. This step-by-step tutorial not only shows how you can merge a mail document from customer information in a Sql Anywhere 10 database, it also shows how you may work with the database. If you are a office worker using 'Office' products this is a must article for you. http://tc.eserver.org/28685.html http://tc.eserver.org/28685.html Many articles have been written on what is probably the single most ubiquitous interface element within Web applications today: the form. Forms justifiably get a lot of attention because their design is critical to successfully gathering input from users. Registration forms are the gatekeepers to community membership. Checkout forms are how eCommerce vendors close deals. But what goes in must eventually come out, and the information users provide to Web applications often makes its way back to users in the form of tabular data. http://tc.eserver.org/28660.html http://tc.eserver.org/28660.html As a human society, we're quite possibly looking at the largest surge of recorded information that has ever taken place, and at this point, we have only the most rudimentary tools for managing all this information--in part because we cannot predict what standards will be in place in 10, 50, or 100 years. http://tc.eserver.org/28616.html http://tc.eserver.org/28616.html Step-by-step procedure explained with a large number of screen shots. Both linking and importing are described. http://tc.eserver.org/28569.html http://tc.eserver.org/28569.html This builds on the previous article, 'MobiLink Synchronization Wizard in SQL Anywhere 10.' The new Deployment Wizard in SQL Anywhere Server 10.0 makes it painless to deploy the model, a task which was script based and terse. http://tc.eserver.org/28526.html http://tc.eserver.org/28526.html A decision support database that is maintained separately from the organization's operational database. Support information processing by providing a solid platform of consolidated, historical data for analysis. http://tc.eserver.org/28522.html http://tc.eserver.org/28522.html A step-by-step must read article on SQL 2005 Reporting Services which creates a report and hosts it on an intranet server. http://tc.eserver.org/28508.html http://tc.eserver.org/28508.html Are you storing data about your constituents in three, five, even ten different databases? If so, you're not alone ' but it's costing you in time, lost revenue and decreased impact. Paul Hagen describes how to get all your data into one place with an integrated CRM strategy. http://tc.eserver.org/28382.html http://tc.eserver.org/28382.html MobiLink is a technology that can help multiple databases synchronized, a key requirement for mobile access to data. The article shows you how to create a model that can be deployed to access data on a SLQ 2005 Server remotely with a SQL Anyhwhere database. A forth coming article descibes the deployment details. http://tc.eserver.org/28364.html http://tc.eserver.org/28364.html The Apache Jakarta POI project consists of Java APIs dedicated to the manipulation of files based on Microsoft's OLE 2 Compound Document format. In this article, you'll learn how to use the APIs of the POI project to read from and write to Microsoft Excel spreadsheets. As you will see, the programmatic liberty to manipulate Excel files represents a powerful offering to the Java programmer.The Apache POI contains a number of components. In this article, we'll be focusing our study on the HSSF component. The HSSF project will provide us with the ability to read and write from XLS spreadsheets. http://tc.eserver.org/28265.html http://tc.eserver.org/28265.html In a previous tutorial you learned how to get started using the Ruby language as a web scripting language by embedding it in HTML. You need some type of database connectivity to do the cool dynamic stuff. So here is a tutorial written by Markus Jais on how to connect to a MySQL database using Ruby. I will be updating and editing this tutorial to include more windows instructions where applicable. http://tc.eserver.org/28266.html http://tc.eserver.org/28266.html If you are a CMS user or web developer then you should know what SQL injection attacks are and how to protect your web applications against them. Hackers are using more SQL based attacks, getting smarter about how to attack a website and using better tools. You have to get a good understanding of how their attacks work if you are going to choose the right software and keep your website secure. Here I will review several types of SQL injection attacks and how they occur. Then take a look at what web developers and end users can do to prevent them. http://tc.eserver.org/28043.html http://tc.eserver.org/28043.html Along with creating a database schema and populating tables with data, being able to selectively modify data is one of the most important skills necessary for a database developer. This article teaches you how to selectively delete or update data in an existing table and how to modify the structure of an existing table. To perform data modifications on a more complex database schema, you'll learn about embedded subqueries, both scalar and table, with data update and data insert operations. You'll also find out how to delete and modify data in complex schemas using the Apache Derby database. http://tc.eserver.org/27944.html http://tc.eserver.org/27944.html This hands-on tutorial should help you in understanding the interface available for querying MS SQL Server 2005 databases. Some of the major features will be discussed as related to their use rather than going into a lot of details. Querying the database is one of the most basic activities that is routinely and frequently performed. http://tc.eserver.org/27748.html http://tc.eserver.org/27748.html If you're a Java 2 Enterprise Edition (J2EE) developer, you'll want to preview the SQLXML technology, currently in development. Check out procedures to create an XML document, store an XML document in a relational database, retrieve an XML document from a database, and navigate an XML document with the SQLXML Java data type. http://tc.eserver.org/27660.html http://tc.eserver.org/27660.html XQuery speeds up the process of finding information contained in an XML document, which is very handy when dealing with long XML documents. This article, the first of two parts, will teach you how to write XQuery expressions. http://tc.eserver.org/27661.html http://tc.eserver.org/27661.html XQuery speeds up the process of finding information contained in an XML document -- which is very handy when dealing with long XML documents. This article, the second of two parts, will teach you how to write XQuery expressions. http://tc.eserver.org/27633.html http://tc.eserver.org/27633.html This is the first article in a series which guides you in designing XML Schemas right from the basics without any hurdles. http://tc.eserver.org/27632.html http://tc.eserver.org/27632.html This is the first article in a series concentrating on implementing relations for designing robust XML schema definitions. http://tc.eserver.org/27631.html http://tc.eserver.org/27631.html This article is the second in a series that shows you how to implement relations for designing robust XML schema definitions. http://tc.eserver.org/27614.html http://tc.eserver.org/27614.html When it comes to providing reliable, flexible and efficient object persistence for software systems, today's designers and architects are faced with many choices. From the technological perspective, the choice is usually between pure Object-Oriented, Object-Relational hybrids, pure Relational and custom solutions based on open or proprietary file formats (eg. XML, OLE structured storage). From the vendor aspect Oracle, IBM, Microsoft, POET and others offer similar but often-incompatible solutions. This article is about only one of those choices, that is the layering of an object-oriented class model on top of a purely relational database. This is not to imply this is the only, best or simplest solution, but pragmatically it is one of the most common, and one that has the potential for the most misuse. http://tc.eserver.org/27286.html http://tc.eserver.org/27286.html Many steps are involved in the process of turning an initial concept for a database into a finished product that meets the needs of its user community. In this paper, we describe those steps in the context of a four-phase process with particular emphasis on the quality-related issues that need to be addressed in each phase to ensure that the final product is a high quality database. The basic requirements for a successful database quality process are presented with specific examples drawn from experience gained in the Standard Reference Data Program at the National Institute of Standards and Technology. http://tc.eserver.org/27215.html http://tc.eserver.org/27215.html Word's sorting capability is fairly rudimentary, especially for those migrating to it from WordPerfect (though it's surprising how many people don't realize Word can sort paragraphs, not just tables – or maybe not so surprising, given where the item is in the menus! The ability to sort on word 2 in field 3 would certainly be very useful (in Excel as well). But there are various things you can do in the meantime. http://tc.eserver.org/27195.html http://tc.eserver.org/27195.html Microsoft Word supports many file formats which can be used as a Data Source for a mail merge. This article covers specifications and frequently asked questions on the most commonly used Data Sources, along with how to set up a Data Source in Word. http://tc.eserver.org/27194.html http://tc.eserver.org/27194.html Mail merge is for simplifying repetitive documents and tasks. Mail merge can be used for creating many documents at once that contain identical formatting, layout, text, graphics, etc., and where only certain portions of each document varies. Mail merge is also used for generating mailing labels, envelopes, address lists, personalised training handouts, etc. As well as hard copy mailshots, it can be used to generate multiple emails and electronic faxes. And it can even be used to create a 'friendly' front-end to spreadsheet or database information. http://tc.eserver.org/27196.html http://tc.eserver.org/27196.html Almost any mail merge will work better if you use IF fields, as the frequently used scenarios discussed below attempt to illustrate. http://tc.eserver.org/27197.html http://tc.eserver.org/27197.html Purists might argue that the power it gives ordinary users isn't necessary because they should use Access queries for this sort of thing and link the merge to the query. But in my experience, many people who are very comfortable working with Word and Excel find Access (or any full-fledged database application) very difficult to work with, and can get the job done far more quickly and easily using a combination of Word and Excel. At the end of the day, getting the job done is what matters. The vast majority of the world's databases (in terms of number of databases, rather than in terms of amount of data) are stored in Excel spreadsheets. http://tc.eserver.org/27098.html http://tc.eserver.org/27098.html While many technical communicators may already have HTML, CSS, or Javascript skills, many may feel that it's time to take the next step: creating a web page that hooks up to a Microsoft Access database. With new, affordable tools, now is certainly a good time to get started. While there are a number of tools that you could use, this article describes Web Matrix as an example that can help you get started with programming and connecting a web page to a database. http://tc.eserver.org/27059.html http://tc.eserver.org/27059.html Some types of searching operations stand apart from others in that they represent a different way of thinking about searching. Perhaps you're displaying a result set one page at a time. Half of that problem is to identify (search for) the entire set of records that you want to display. The other half of that problem is to repeatedly search for the next page to display as a user cycles through the records on a display. Your first thought may not be to think of pagination as a searching problem, but it can be thought of that way, and it can be solved that way; that is the type of searching solution this chapter is all about. http://tc.eserver.org/27057.html http://tc.eserver.org/27057.html A function is a special type of command word in the SQL99 command set. In effect, functions are one-word commands that return a single value. The value of a function can be determined by input parameters, as with a function that averages a list of database values. But many functions do not use any type of input parameter. http://tc.eserver.org/27058.html http://tc.eserver.org/27058.html Even if the vast number of end users leads to high calculation loads outside the database, you can generally throw hardware at the application load (the load outside the database, that is), hanging as many application servers as necessary off the single central database. http://tc.eserver.org/27036.html http://tc.eserver.org/27036.html If you are a Microsoft Access user, you'll be happy to know that you can export Access 2003 data as XML. http://tc.eserver.org/26794.html http://tc.eserver.org/26794.html It's likely that few professionals worry more about how their services are perceived than librarians. Lawyers may have more reason for concern, but many of them laugh all the way to the bank. We have little if not our reputation. So the new report published by OCLC, '€œPerceptions of Libraries and Information Resources,' deserves notice. Do libraries still matter? On what level? Will library use likely increase or decrease?--generated heartwarming comments but also much to cause concern. http://tc.eserver.org/26262.html http://tc.eserver.org/26262.html Documenting a database during its development is a best practice to ensure that the organizational schema, data objects, and other related information are captured for future reference. http://tc.eserver.org/26226.html http://tc.eserver.org/26226.html What is a knowledge base? What are the components necessary to build one? http://tc.eserver.org/25977.html http://tc.eserver.org/25977.html Today, we can find many applications to manage XML content that demonstrate the power and flexibility that can only be achieved through XML-native databases. Information intensive companies such as the airline and manufacturer described in this paper have achieved significant technical and business benefits from their use of XML standards and database technology over alternative approaches. http://tc.eserver.org/25906.html http://tc.eserver.org/25906.html Can you trust the leading open-source database engines, PostgreSQL and MySQL, to deliver the performance and features that the Oracles, SQL Servers, and DB2s of the world do? Not just yet, but they could offer enough to meet your needs. Find out how they stack up against each other, as well as against the commercial alternatives. http://tc.eserver.org/25623.html http://tc.eserver.org/25623.html The notion of an integrated project database (IPDB) has existed for decades. Over that time many projects have been undertaken to develop the technologies and frameworks required to implement an IPDB. Also over that time, there has been promotion of the benefits and impacts that IPDB systems will have on the industry. As there are still no industrially stable IPDB systems in existence, the industry's perception of what they are and what they can do has diverged from many of the original presentations. It is also clear that researchers and de-velopers involved in IPDB development have many different ideas about what constitutes an IPDB and what is, or is not, possible to create. This paper aims to describe misconceptions which are growing up around IPDB systems, and presents the authors' view of reality (informed by the opinions of the UK network of experts in ob-jects and integration (URL-1 1999) which was run by the DETR). http://tc.eserver.org/25373.html http://tc.eserver.org/25373.html Till now there was no efficient way to embed the access to the MySQL database into a VB application. http://tc.eserver.org/25372.html http://tc.eserver.org/25372.html A large percentage of MySQL users are using MySQL on a web server hosted by an ISP. Most hosting providers block port 3306 (the MySQL server port) at the firewall, preventing outside access to MySQL. This is an important security practice and you should be very concerned if your ISP does not block port 3306. In this article I will demonstrate how to connect the MySQL GUI tools, including MySQL Administrator and MySQL Query Browser, to a remote server using SSH port forwarding. This article will be written with the assumption that the reader is using Microsoft Windows, but the principles presented will be applicable to Linux users. http://tc.eserver.org/25374.html http://tc.eserver.org/25374.html This article discusses writing software that helps the user effectively work with large amounts of data. The approach that I will describe is called filtering. http://tc.eserver.org/25351.html http://tc.eserver.org/25351.html Most users at one time or another have dealt with hierarchical data in a SQL database and no doubt learned that the management of hierarchical data is not what a relational database is intended for. The tables of a relational database are not hierarchical (like XML), but are simply a flat list. Hierarchical data has a parent-child relationship that is not naturally represented in a relational database table. http://tc.eserver.org/25341.html http://tc.eserver.org/25341.html An online resource for people developing database-driven web applications using Visual Basic and MySQL. http://tc.eserver.org/24997.html http://tc.eserver.org/24997.html Once you've built several MySQL databases, you'll learn some shortcuts to database design. Why stop there? Take this trick a step further and put together a generic database with a set of empty, standard tables. With a well-designed MySQL template, you can quickly assemble the basics of any database as needed. A template also allows you to focus on the more interesting aspects of a database project. http://tc.eserver.org/24996.html http://tc.eserver.org/24996.html When users ask for advice about their database applications, one of the first things I try to help them with is the normalization of their table structure. Normalization is the process of removing redundant data from your tables in order to improve storage efficiency, data integrity and scalability. This improvement is balanced against an increase in complexity and potential performance losses from the joining of the normalized tables at query-time. http://tc.eserver.org/25000.html http://tc.eserver.org/25000.html CVS, part of the glue that holds open source development together, is showing its age. Many competitors have emerged recently, fixing misfeatures and adding new ideas. Shlomi Fish explores several current open source version control systems that may be better than CVS for your needs. http://tc.eserver.org/24065.html http://tc.eserver.org/24065.html Notes databases can provide versatile environments for developing and sharing knowledge globally through both client-based and Web-based applications. In this panel discussion we explore some of the issues facing information designers as they enable communication and collaboration in work groups. We will focus on how to determine if Notes is an optimal solution, how to translate information needs into effective design elements and functionalities in Notes, and how we can help ease the transition to the world of Notes for new users. http://tc.eserver.org/23809.html http://tc.eserver.org/23809.html MySQL is old news ...or is it? In this fast-paced expose, Blane looks at where MySQL is now, and what's planned in Versions 4.1 and 5 - including the exciting developments of MySQL Cluster and Stored Procedures! http://tc.eserver.org/22750.html http://tc.eserver.org/22750.html Topic Maps provide a very flexible and robust way to add arbitrary data to a relational databases at runtime. Moreover, Topic Maps come with a predefined exchange mechanism (the XML Topic Maps (XTM) interchange syntax) to allow data to be exported to XML. http://tc.eserver.org/22678.html http://tc.eserver.org/22678.html This detailed, inclusive database tutorial is designed for beginners and those ready to dive in. Easy-to-understand definitions, real-world anecdotes, and concrete examples set this site apart from the others. http://tc.eserver.org/22656.html http://tc.eserver.org/22656.html The Web-surfing public doesn't really care about flashy-yet-useless technology. They want Web sites that do something for them: provide a service or entertainment; help get a job or a date; check bank account balances, stock prices, interest rates, availability of airline tickets, today's weather ... and so on. http://tc.eserver.org/22589.html http://tc.eserver.org/22589.html Buzz about the value and implications of XML has reached an all-time high, with lofty claims of its potential to transform business and society, doing everything from simple document formatting to curing the common cold. I don't recommend you empty your medicine cabinet just yet. However, do take seriously the developments surrounding XML and its associated technologies. While XML might not merit all the hyperbole, it remains useful. Knowing how to apply this simple meta-language can help you create solutions that will give you a strong competitive advantage. http://tc.eserver.org/22406.html http://tc.eserver.org/22406.html Whether you want to build your own forum, publish the messages from a mailing list on your Website, or write your own CMS: there will be a moment that you'll want to store hierarchical data in a database. And, unless you're using a XML-like database, tables aren't hierarchical; they're just a flat list. You'll have to find a way to translate the hierarchy in a flat file. http://tc.eserver.org/22404.html http://tc.eserver.org/22404.html As MySQL developers, we are often required to keep two databases in complete sync with one another. http://tc.eserver.org/22330.html http://tc.eserver.org/22330.html Released in January 1998, MySQL is an open source relational database management system (RDBMS). It's based around the Structured Query Language (SQL), and is best for managing the content of the database as opposed to transactions, as MySQL does not support COMMIT or ROLLBACK. One of the biggest drawbacks of MySQL is it's lack of support for referential integrity, no stored procedures, no triggers, and no sub-queries. MySQL is free, and may be downloaded from download section at MySQL. http://tc.eserver.org/21989.html http://tc.eserver.org/21989.html Unlike previous versions of data warehouses (people and books), that might be considered the australopithecines of the database lineage, libraries crossed over into the modern-day species. http://tc.eserver.org/21934.html http://tc.eserver.org/21934.html Whether you know it or not, 'database publishing' probably describes some of what you do. Here's how to do it better! http://tc.eserver.org/21221.html http://tc.eserver.org/21221.html Protect your data from crashes and the confusion of multiple user requests with a transaction-capable database. http://tc.eserver.org/20373.html http://tc.eserver.org/20373.html Using relational databases to create HTML. http://tc.eserver.org/19486.html http://tc.eserver.org/19486.html To jump-start revenue growth, Mark Jarvis has insisted that simplicity be the foundation not only of Oracle's marketing but also of its product development. Programmers, salespeople, and marketing staff now work closely to satisfy real customer problems, not just deliver glitz. On Nov. 18, Mark Jarvis spoke with BusinessWeek Online Technology reporter Jane Black about his plans to improve Oracle's fortunes. Here are edited excerpts from that conversation. http://tc.eserver.org/18827.html http://tc.eserver.org/18827.html The phrase database design means the set of steps, techniques, guidelines, and tools for translating a logical data model into a database specification. The database design consists of a structural representation, but may also include an integrity representation for rules enforcement. The structural representation is usually a database design diagram, from which you generate database-specific definitions. The integrity representation can take many forms from database specifications that define rule enforcements in the dbms layer, program specifications that define rule enforcements in object methods or other implementation, as well as specifications that define rule enforcement in a rules layer. Think of relational database design as a process for transforming the Logical Data Model into a relational database where the database design preserves the high quality properties of the Logical Data Model described in the book.
