Comparison of tools for application's integration

In this diploma thesis, I focus on the application integration. Main goal of this thesis is comparison of integration platforms of the biggest vendors on the market, there are products of companies Microsoft, IBM, Oracle and SAP. I compare these products according criteria, which I had chosen. I use mainly own experiences with the products to achieve a goal. These products I compare with respect to general, technological and possibility of using point of view. My work can be as a source for decision, which of the integration platforms is optimal to use. Then I describe one of them - Microsoft Biztalk Server with simple example. The next goal of this work is to summarize the theory of application integration, where I describe the possibilities of integration's application from the simplest till the most complicated. The next goal of this work is making a methodology in Biztalk Server, which will contain concrete solutions and techniques in different situations. This methodology can help developers and analysts to make better proposals, more convenient solutions and beware of needless problems.
