Study Of CORBA And Its Application In MIS Of Human Resource

CORBA is an opened standard Architecture based on distribute object, independent on platforms and computer languages with interaction between distribute isomerous environment. The software with CORBA is not object-oriented but can be reused, migrated, and extended. CORBA is excellent in isomerous environments and becomes an important technique for enterprise multi-layer application system..Recent years, international research and development on CORBA enters a new area. It is important for theory study and our country software development to learn about its technique progress and its application. Using these in enterprise information systems, electronic commerce, etc, it will bring considerable economic performance for the society and the social performance. The result of this paper is useful for system designers and developers who are prepare for setting up enterprise application systems with CORBA.This thesis researches the system structure, kernel and principle, and application of CORBA. It also studies the technique of accessing database, UML, and object-oriented. Using an object-oriented language, it designs and realizes function models to operate data from databases and their service interfaces. This system has advanced system structure, good availability, easy maintenance, and expansibility, with object-oriented kernel models. It can be used in different hardware platforms and operation systems. It optimizes the system's performance to design IDL interfaces, select CORBA transfer fashions, and frame database structures.Based on CORBA 2.3, this thesis introduces carefully its basic theory and the system structure of ORB(Object Request Broker). Then, it concentrates on techniques and applications of CORBA. Finally, based on the author's project, it gives an application example which could apply in different operation systems with CORBA models.
