数字线划图(DLG)管理系统研究与开发

Research and Development for the Management System of Digital Line Graphic(DLG)

通过分析数字线划图数据目录文件管理方式的缺点,提出了利用数据库管理数字线划图数据的思路。结合实际应用给出了数据库设计,采用AutoCAD+SQL Server模式开发了数字线划图管理系统,应用效果显著。

Considering the disadvantage of the file catalog management to digital line graphic （ DLG）, this paper gives a practical method for managing DLG. Contrasting the two methods for managing DLG, the paper provides the database frame and develops the system platform. Based on the AutoCAD and SQL Server model, the management system has proved to benefit the consistency of various data sources in our department.
