Abstract


With the object-oriented technology is deeply rooted in the hearts of the people , object-oriented database systems are gradually be applied to a large number and broad areas . Zhejiang University, intelligent software laboratory design and development of object-oriented database system ONet for spatial data storage and intelligent decision-making system support for Geographic Information System data persistence , and achieved initial success . Increasingly large-scale applications put forward higher requirements gradually on ONet system . ONet from version 3.0 after attempt of the components transformation components transformation of the original intention in order to provide the user object assembly programming environment to solve the problem of object schema evolution . This paper studies the functional structure of the system ONet organization previous componentization work poorly defects , the inherited object components thoughts based on a clear purpose and principles of the separate components , and put forward a new group pieces of reconstruction programs, and the use of this program a thorough implementation of the interface programming . ONet the component system reconstruction work after the completion of the various components in the form of a dynamic link library released . ONet system for the first time realize the goal of the object assembly programming environment for application , the object components thought from theoretical research to practical application . The new system structure , compared with the previous clearer , easy to upgrade and maintain multilingual for ONet systems in the future is bound to achieve maximum code reuse .
