The Application Of The CORBA In The Database Manage Information System

CORBA is the result of the Object-Oriented Software-Engineering development. It is the most important research direction of the computer science and technical in these years.The article base on the LIMS(Literature Information ManagementSystem)system's research and development, Introducing the CORBA------includethe base conception in CORBA, model, architecture and feature; The article describe the Multi-layer architecture's feature and analyse the Middle-ware technology's exert in the Multi-layer architecture's system. The article describe two strategays of control by the example of the LIMS system, and give a example of a object-model's building.The article's first chapter introduce the CORBA's definition and its architecture and its feature; Search CORBA's supplement to the distribution compute and object-model, allusion the Middle-ware's conception.The second chapter describe the achieve of the CORBA architecture under the normal C/S mode;And use a example to explain it.The third chapter introduce LIMS system's Multi-layer architecture and its step and feature,Analyse the Object-Orient component technology's using in LIMS system's building of the Object-model;Give the code example of the OMG IDL that correspond the CORE A. And introduce two control model in the LIMS.The fourth chapter introduce the CORBA's application in the DataBase by the example of the LIMS system,In particularly describe the supplement of CORBA in ORACLE database system.
