Lixin Du · 2010
Enterprise Application Integration (EAI) problems are one of the major challenges IT departments are facing today. At the same time, Service Oriented Architecture (SOA) has become the preferred methodology to build complex enterprise applications. Current researches on EAI are mainly focus on different systems integration. We observe that there are some applications in the state-owned monopolies need to be integrated. These applications have similar function but belong to different corporate levels. Similar function is developed repeatedly in different applications or companies. We name these systems Vertical Application System (VAS). In this paper we analyze the Vertical Application System and give its SOA-Based architecture. We also show our practical solutions for service reuse, service migration and service evaluation.
