利用元数据确定封闭模块的数据结构

提出一种通过数据库管理系统中的元数据来确定封闭模块中未知的数据结构的技术。通过利用数据库中的元数据确定封闭模块中用户建立的数据表，并在模块的应用程序运行时动态跟踪数据表的记录条数的变化来确定封闭模块中的部分数据结构。并以SQL Server2000为例，详细描述如何利用数据目录中的sysobjects系统表来确定封闭模块的数据结构，该研究结果在实际信息系统开发中有利于信息系统的集成。

Closed Module's Data Structure Determination by Using Meta-data

A kind of technology is introduced, which uses meta-data in database management system to make clear data structure which is unknown in closed module.It is suggested that the table created by closed module is made clear by using the meta-data in database and a part of the closed module's data structure is made clear by dynamically tracking the changing of record count when the application in module is running.Simultaneously,SQL Server 2000 is used as an example to describe how to utilize a system table named sysobjects in data directory to make clear the closed module's data structure,which is helpful to integrate information system in practical information system development.
