Konvertering av CRM-system från ASP till ASP.NET
S2 CRM is a Customer Relations Management system built in classic ASP that runs on a web server servicing customers with varying needs. The purpose of this thesis work is to convert parts of the system to the web development environment ASP.NET. The purpose is also to gain knowledge of the framework itself. The ASP.NET environment is compared with another framework, JBoss Seam, in order to understand the differences and to evaluate the possibility of using another framework than ASP.NET, when building the new system. The outcome of this comparison is that although JBoss Seam is just as good, and in some aspects better than ASP.NET, the use of ASP.NET simplifies the continuation of development on the S2 CRM product. The conversion that was made includes a way to share information between the new and the old system, an implementation of listing and search modules and an approach to the data model and techniques for achieving good performance. Modularity is also an important aspect of the work, and this was achieved by constructing controls that can be used in different contexts, configurable by configuration objects. The result of the thesis is a basic system for listing and searching that can coexist with the original system and that can be built further upon to create a new version of S2 CRM that fully runs on the ASP.NET platform.
