Colleges’ Information Integration And Application Based On The Framework Of OSGI And REST

With the continuous progress of education informatization, education information technology has entered the stage of comprehensive promotion and application-specific. First, the long-term accumulation of data, making the normal running of the school is heavily dependent on information technology resources second, the information system is more and more related to all aspects of the normal running of the school. It results in a multi-phase interleaved complex system, with heterogeneous framework and tightly coupled module makes it difficult to integrate, and cannot achieve the desired effect.It is time to break the shackles of the existing University information system environment, and changes with the external environment, the integration of information resources, reduce data redundancy, eliminate islands of information.The author, based on the actual needs of the school, through the analysis of the current situation and development trend of information integration, information integration solutions proposed lightweight OSGi and REST-based open system architecture. OSGi open source project Felix framework modules to be dynamically deploy and module combination of characteristics, Bundle, static scheduling and automatic release by writing dynamic expansion module implements a combination of dynamic binding service, a better solution to the integration of information technology systems dynamic The lack of tight coupling and module boundaries are not clear. We selected a few of the more typical system, through a unified service interface definition, dynamic expansion of services, intelligent identification of business components, to establish the association between the reference system, to achieve a flexible combination of business processes, the integration of business data, and ultimately achieve the integration of information technology purposes. The REST lightweight Web services program to release the software interface using JSON format to reduce network traffic, reduce redundant data and improve system performance, eliminate islands of information.Experimental results show that the loosely coupled open systems based on OSGi and REST provide users with a unified access interface, strengthen the sharing of resources among the various systems, achieve effective integration and utilization of data.
