摘要
基于SQL数据库技术的IETM系统,联合式IETM的结构是3层结构的Browser/server,可分解为一个应用服务器和一个或多个数据服务器,与客户端一起构成3层B/S模型。服务器是数据库的载体,每个服务器可以承载一个或多个数据库。其ADO通过访问OLEDB数据提供程序访问数据库。查询定位过程则为:先对系统外部实体进行虚拟URL地址化,然后通过地址的链接完成对系统的交互式操作。
The IETM system is based on SQL database technology. The united IETM structure is three-layer Browser/ server. Then, decompose the application server and one or several data c and combine with client to establish three-layer B/S model. The server is the carrier of database. Every server can carry one or several database. ADO interviews OLEDB data and provides program with database. The inquiring and orientation process includes： carry out virtual URL location for system exterior entity at first; then, realize system alteration operation through address linkage.
