Business Requirement Oriented Enterprise Application Integration Model Design And Telecom Industry Application Research

Researches on enterprise application integration currently almost focus on new technologies development and system architecture enrichment. However, it is very rare to pay attention to customers' business requirements and a comprehensive EAI architecture is also lack with consideration of business requirements. To solve problems above, the paper is aimed on study EAI as follows.1. A business requirement-oriented EAI model is proposed, and a relatively complete theoretic integration system is built.The paper introduces business requirement and capacity requirement into EAI model and studies every level. Through extracting business requirements, capacity requirements are then transformed into business processes which are to be improved. With services discovering, registering and invoking, business processes are reengineered so that business requirements are satisfied. It offers enterprises a method to transform business requirement into process and system building by this model.2. The business requirement-oriented EAI model is applied into the whole operating scenario of telecom industry, which shows practical application.In the whole operating scenario of telecom industry, the paper analyzes telecom business requirements and establishes its relationship with operation capacity requirements. Referred to NGOSS and eTom model, business processes are found to support capacity requirements. Taking product on-market process for example, the paper completes the service discovery and service combination. Finally, telecom application integration model in the whole operating scenario is established and offered reference for industry practice.3. The product on-market process is simulated, which validates flexibility and maximum use of existing IT resources of SOA approach.The paper uses IBM Websphere software to simulate product on-market process and realize the service implementation. After simulation and dynamic analysis of the previous process, new process is designed and implemented by service orchestration and interface invoking. The advantage of SOA is validated in business process reengineering.
