Most developers dread dealing with HTML tables and cells to build their Web sites. For one thing, tables make it difficult to modify the site later or to change its appearance. Discover some basic techniques for writing Web sites that you can later re-skin by using templates during the site's initial creation. Also, learn why you should use data-driven techniques for your own Web sites.
With the growing use of dynamic web content generated from relational databases, traditional caching solutions for throughput and latency improvements are ineffective. We describe a middleware layer called Ganesh that reduces the volume of data transmitted without semantic interpretation of queries or results. It achieves this reduction through the use of cryptographic hashing to detect similarities with previous results. These beneﬁts do not require any compromise of the strict consistency semantics provided by the back-end database. Further, Ganesh does not require modiﬁcations to applications, web servers, or database servers, and works with closed-source applications and databases. Using two benchmarks representative of dynamic web sites, measurements of our prototype show that it can increase end-to-end throughput by as much as twofold for non-data intensive applications and by as much as tenfold for data intensive ones.
When query results exceed the display area then you resort to scrolling and wish you had some way to limit the number of results displayed and comfortable to view without scrolling. Paging functionality which provides an answer to this is therefore a much desired feature. The Data Pager Control in Visual Studio 2008 provides this functionality when you create an ASP.NET web form under .NET Framework 3.5. It can be configured automatically using the GUI, or it can be installed manually after installing the ListView. In this article both of them are described. While the number of items displayed in a list can be declaratively coded, it is possible to set it at page load time as well.
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.
I recently purchased a music streaming website, powered by MySQL database full of links to the musical content. In order to transfer the website to my hosting I was going to need to import the database. Unfortunately, I host with GoDaddy.com. GoDaddy offers phpMyAdmin to control your databases which is a great program but it limits imports to 2MBs. My database was over 70MB. I tried it anyways with my fingers crossed but as expected, it wasn’t going to work.
MySQL combined with PHP is a powerful tool. However, most beginners won’t know where to start, on how to extract the data from their databases, or what have you. There is just about 50 MySQL functions in PHP, all used to help you accomplish what you need with PHP. However, you’re probably not going to use them all, and below I’ll explain the key features.
Many organisations are attempting to clarify the relationship between the corporate intranet, and their document/records management system. While this is a broader issue of information management with an organisation, there are some short-term activities that can be taken to create a working relationship between these two platforms. This briefing outlines a simple scenario in which the intranet helps staff find key corporate information, while the documents accessed are stored in the document/records management system.
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.
