M ( 4 ) do a deep research on the privilege management of the engineering database system co - s _ dbs, and aimed at the requirements of the cooperative design for the privilege management, purpose a privilege management model s _ pmm. this model can not only provide the well - designed structure of the privilege control table and the paniculate privilege control, but also support role mechanism, positive and negative privilege mechanism, concealed privilege mechanism, which well satisfies the requirements of the cooperative design
（ 4 ）對co - s _ dbs工程數據庫系統的權限管理進行了深入的研究，針對協同設計對權限管理的要求設計了權限管理模型s _ pmm ，該模型提供了設計良好的權限控製表結構，細粒度的權限控制，支持角色機制、正負權限機制、隱式權限機制，很好的滿足了協同設計的要求。 -
This paper mostly describes the research and realization of some key technologies in the talent database of science and technology in guangdong, which include the system architecture, web - db accessing technology, application programming model, capability optimize and security. 1 ) there are many kinds of architectures of web - dbs, such as b / s architecture, b / s / s architecture and multi - tiered b / s architecture
本文主要描述了廣東省科技人才庫系統中若干關鍵技術的研究和實現，主要包括： 1 ）從體系結構的角度來看， web數據庫系統可以採用b / s 、 b / s / s和多層b / s體系結構。 -
With the rapid developing on internet and related technologies, distributed database system ( ddbs ), compared with share - based dbs, will become the dominated application in future ' s network environment. however, differences in network structure, protocol and bandwidth have become a several issue that ddes should overcome when data flows pass through the network nodes
然後就本課題中所面臨的兩個問題作了詳細介紹：分散式數據庫系統實現過程中的網路擴充問題；分散式數據庫系統實現過程中大規模可靠組播協議（ larmp ）的設計。
