摘要：

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.
