Abstract

In this dissertation we discuss the process of implementing the Windows Workflow foundation model in existing applications. We present several possible approaches to solving this problem and their advantages, as well as limitations. First, we describe the main concepts behind Business Process Management and the Windows Workflow foundation programming model. Other related technologies are also described, including .NET Framwork, Windows Communication Foundation, ASP.NET etc. The practical part of this dissertation focuses on introducing the WF model into an existing application – AdLeasing. We present the goals of introducing the WF model and discuss specific issues, pertaining to its use with different types of applications, such as ASP.NET. It is the author's opinion that the problem of maintaining different versions of workflows is an issue often overlooked in existing literature so a significant part of the discussion focuses on this issue. Finally, we present the procedures used to implement the WF programming model into an existing application. We focus on two business processes where using the WF model is likely to have the greatest benefit and also describe several shortcomings of the model, identified during this process.
