The architecture of Web applications has changed, with the addition of AJAX support. USoft web applications use AJAX technology. In general, this results in a reduced network and server load since lots of data will be stored on the client. This results in a better performance compared with previous USoft versions.

AJAX (Asynchronous JavaScript and XML), is a group of interrelated web development techniques used to create interactive web applications. Using Ajax, USoft web applications retrieve data from the server asynchronously in the background, without the need to refresh a web page, and without interfering with the display and behavior of the existing web page.

All data in Web Designer pages is linked to data sources. The advantage is that each control that extracts its data from a data source automatically benefits from the AJAX technology.

All server actions except the executeSQLStatement action are executed asynchronously using AJAX technology - there is no need to refresh the web page. This results in an improved look and feel for your web application.

This has consequences for the way in which applications work. For example, the Synchronize On property is no longer required.
