基于分布对象Web的主流数据库集成系统

面向新一代的分布式对象Web体系结构，将全局数据库技术，全局数据库事务管理技术，主流数据库对象化组件技术和先进的CORBA对象技术综合成一体，在支持异构分布式系统的CORBA机制，全局数据库模式，全局查询语言的定义，语法和语义分析，查询优化，主流数据库的对象化表示，事务的管理，并发控制，安全管理，全局事务的完整性处理，主流数据库的集成工具，多数据库系统的管理和维护策略等方面，针对实用化的目标开展研究并加以实现。

INTEGRATED SYSTEM OF MAINSTREAM DATABASES BASED ON DISTRIBUTED OBJECT OF WEB

Discussed in this paper is web-based architecture of the next generation of distributed object, with emphasis on how to integrate global database technology, global transaction control technology, mainstream database component technology and CORBA technology. Also studied are the aspects on CORBA mechanism sustaining heterogeneous and distributed system, global database schema, the definition of global query language, syntax and semantic analysis, query optimization, the objective expression of mainstream databases, transaction management, concurrent control, security management, the integrity of global transaction, integrated tools of mainstream databases, and the management and maintenance strategy of multidatabase systems, and finally realized are objectives based on the study.
