Design And Implementation Of Corba-based Computer-aided Assembly And Management System

The Common Object Request Broker Architecture (CORBA) is an emerging open distributed object computing infrastructure being standardized by the Object Management Group (OMG), which used for network computers. There are two key parts in the criterion to implement the interaction between different computers: OMG Interface Definition Language (OMG IDL) and standardized protocol GIOP and IIOP, which allows software based on CORBA can communicate with each other no matter where they come from the same company or different companies.Scientific research and produce both are important and close to each other in a scientific research and productive institute. Information should be shared to avoid mistakes and to correct the design defects. Designing, buying materials, assemblage are the key element of the scientific research and produce. Designing is the foundation of all, buying materials and assemblage are very important, trouble and hard to managed parts of all.The main purpose of this system is to be used in the device assemblage and management procedure of an institute. It displays some unit properties with multimedia, manages assemblage progress and materials and provides some guidance to the whole assemblage of the device during the whole assemblage phase. This system is developed to promote the work efficiency and shorten the produce and maintenance cycle.The following is the characteristics of this system:(1) It bases on three-tier architecture of CORBA.(2) There are an assemblage tree to display the device structure and some flash to guide the assemblage procedure.(3) All of the modules can run together and also can run independently.(4) The flow management module is suitable to the actual situation of the institute.(5) The permission management is safe and convenient.
