The application is a web-based , various companies and car dealers can use it without installing any software on their computers, they can easily reach it through the Internet using their favorite browser. During the development process I used technologies supported by the . NET framework, i.e. ASP.NET for the user interface and ADO.NET the implement data access with the MS SQL database. Several implementations of the AJAX web development techinque are used to make the graphical user interface more responsive. The first part of my dissertation is about the characteristics of web based applictions. The following section is about CRM systems, contains the functions those are expected of such an application.
