In a service-oriented architecture (SOA), a change or shutdown of a particular service might have a significant impact on its consumers (e.g., IT systems). To effectively cope with such situations, the IT systems affected by a service change should be identified before actually applying the latter. For this purpose, a SOA repository with advanced analysis capabilities is needed. However, due to the numerous complex interdependencies between service providers and consumers, it is a challenging task to figure out which IT systems might be directly or indirectly affected by a service change and for which period of time this applies. This presentation tackles this challenge and presents the design of an advanced SOA repository enriched with analysis capabilities. In particular, this repository enables automatic analyses to detect already existing problems (as-is analyses) as well as problems that might occur due to future service changes (what-if analyses). Respective analyses will foster the development of robust service-oriented applications.
