Research And Implementation Of The Teaching Resources System Based On SOA

Service-Oriented Architecture (SOA) is one of the software frameworks used in the network's business integration; loose coupling, service reuse and independent of platform etc. is the main feature of SOA. And it will be used widely as an efficient solution to enterprise application architecture.The Computer Fundamentals Teaching Unit has several software systems, these system adopted different architectures and located on different server, to integrating the existing computer software resource, this paper designed a new computer teaching resources system based on SOA. The new system shields location and architecture of the low-level software systems from users, provides a unified client to users and ensures the design of the new system do not affects the use and improvements of the original system at the same time.This paper will introduce the design progress of the new system in detail, and it will be divided into two parts.First, this paper proposed the Three-Layers Architecture enterprise application architecture based on the features and design methods of SOA infrastructure, give a detail description of the functions in every layer. To improve service reuse of this new system, this paper do a lot more work on service-oriented enterprise application architecture, and adopt business management to improve the Three-Layers Architecture, and designed the Five-Layers Architecture based SOA. This paper also did some research on the implementation of the system and business progress of SOA, give the final steps of how to use SOA in the new Computer Fundamentals Teaching Unit.Second, analysis the existing resources, split the resources into suitable service granularity according to different demands from the users, use the Five-Layers Architecture into integration of the resources. This paper depicts main architecture of the system in detail, describes the main design method of the framework of the new system, and uses examples to illustrate how the business flow syncretism with SOA, finally, this paper depicts the specific implementation of every layer.
