Research On Educational Resource System Integration Based On SOA

At present,most of campus's educational resource system has gradually formed a so-called "information islands" because of the heterogeneity in platform and development tools.If we still integrate the systems in a traditional way,it may lead to high cost and waste of time.SOA with its high degree of abstraction and flexibility,has win the prase in the industial field and become the preferential way for campus's educational resource system integration.In view of this situation and development trends,the basic conception and architecture of SOA is firstly discussed.Then this thesis analyzes the disadvantage of Web Service as an implementation technology of SOA,and points out the advantage of SCA and SDO programming model.On the basis of the work mention above,this thesis designs a system integration framework based on SOA with SCA and SDO as its implementation,analyses the technology for each layer of the integration Framework in depth,and clarifays the features of the integration Framework.Then,in order to integrate the existing resource system,this thesis designs an educational resource integration system based on SOA,realizing a unified resource management platform.This thesis analyzes and designs the whole functional structure of the system and the function that each module should implement.The system's authority management is based on the Role Based Access Control(RBAC),which is convenient for the expansion of the system.According to the CELTS-3 and CELTS-41 specification,this thesis analyzes and designs the data model of the system,standardizes the description of the property for educational resource.At last, based on the service-oriented analysis and design,the process of system's implementation is described in details in this thesis,involving service-finding,service specification, and service module division,construction and implementation.
