AJAX call using an ASP.NET web page
Mar 9th
We already saw what an AJAX call is and the different types there are. Today we’re going to see how to perform an AJAX call using a regular web page at the server. The page will be the connection between the client’s web browser and the server. It will take care of performing the operations at the server (let it be some kind of processes or calculations, or just a regular database access).
I’ll be using jQuery in this example. jQuery is a superb Javascript framework, and is the one I use the most. If you don’t know what it is yet, then the first thing you should do is getting acquainted with it. This JavaScript framework has many convenient functions to make an AJAX call. These functions hide much of the complexity of an AJAX call: you can forget about the XMLHttpRequest object if you wish, and only worry about what to do with the data once you get it back from the server.

Today’s web applications are unthinkable without AJAX techniques. These techniques provide an improved user experience, and tighten the gap between traditional desktop applications and web applications. This means that mastering AJAX technologies is a must for anyone who’s doing serious web application development. In this article I’ll explain the basics of AJAX, and I will show how to program some AJAX calls using ASP.NET technology.
Sluggish database view? Materialize it!
Jan 26th
The other day we were having some slow database view at our project. It was the main view of the new module we were developing, and it was slowing down the whole application to an unacceptable point. It was a rather complex view and could not be optimized much more. So, what was the solution we adopted? We materialized the view.
Regular views store just the SQL script needed to retrieve the data, and every time they are consulted the stored SQL query is executed. However, materialized views not only store the script, but the retrieved records as well, making it much faster.
