SOA-based Agile Enterprise Service Bus

This thesis theoretically illustrates the significance of a system of SOA (Service-Oriented Architecture, a service-centered structure), which is applied and integrated as Enterprise Service Bus. It also discusses the basic model that is based on an integrated platform of SOA. Combining with the characteristics of finance industry and the service demand of policy-type banks, it presents the specific designing object and principle of the enterprise integrated application platform—AgileESB (Agile Enterprise Service Bus). At the same time, the thesis makes a detailed description in the structure, the principle of work and the solution of AgileESB.The design of AgileESB focuses on three core points: the under-system communication, the information transformation, and the service route. Based on these, AgileESB offers relevant solutions for finance industry's special needs of concurrency, reliability, security, expansibility, and manageability to make sure that the bank will becomethe pivot of supporting business expansion in the near future.AgileESB is mainly composed of the following modules: the module of dispatch, information transformation, connector, service web management, security management for data, security application, filter, system management, monitor, batch processing, combination service, recheck, authorization, task list, incident management, ID management, integrated testing and performance testing. Which are both relatively independent and interrelated. what's more, by applying some designs and analysis methods such as IoC (Inverse of Control), AOP(Aspect Oriented Programming), OOA(Object Oriented Analysis) and OOD(Object Oriented Design) in the system, on the premise of the port rules that are established by AgileESB, all modules above can be replaced or expanded to support newly appeared business demand to the largest extent, and consequently be integrated into tech-development trend in the future to assure its orderly for extension and change.Admittedly, AgileESB has its deficiency because of the limitation of the project period, f individual needs of clients, universality and lack of design tools; however, it can be perfected and improved in the prospective system upgrading.
