基于XML的CAD图形数据库开发及应用

为了实现给排水设计的信息化和自动化程度，建立了一种针对给排水设计．的图形数据库，同时为了实现CAD信息在各相关专业中的网络传输和数据共享，推动企业信息化的共享和集成，采用基于XML的CAD中性模型来储存和统一管理设计中产生的相关数据。利用XML易扩展、独立于平台等优点，可以有效地实现项目数据在不同应用中的共享，并有利于与国际标准接轨。

Development and Application of CAD Graphical Database Based on XML

The graphical database was established to achieve informatization and automation of water and wastewater engineering design.In order to achieve network transfer and data sharing of CAD information in relative specialty to push ahead with information sharing and integration in enterprises,the XML-based CAD neutral model was adopted for storing and unified management of data in the design.To take advantage of readily expansible XML that was independent of platform can effectively achieve data sharing in various applications,and was in the interest of keeping in line with the international standard.
