基于XML技术的三维仿真模型的存储

The Storage of 3-D Simulation Model Based on XML

基于仿真的采办是美国国防部于1997年提出的一种新型武器采办体系,分布式产品描述是它的四个关键技术之一,是一种以产品为中心的分布式信息的集合,通过网络技术互联,形成逻辑上统一的关于产品的描述。该文探讨了分布式产品描述中的关键问题之一——数据的分布式存储问题,提出了以Oracle9i数据库作为后台建立分布式数据库的解决方法,并实现了将虚拟现实建模语言建立的三维仿真模型用XML语言描述后,通过JDBC存入分布式数据库,同时给出了从VRML到XML转换的规则,以及转换要遵守的XML Schema文档的定义方法。

Simulation Based Acquisition is a new system of weapon acquisition. Distributed Product Description is one of its four key technologies. It is a set of distributed information interlinked through network to form a logical uniform description about product. This paper discusses the issue of distributed storage of data of Distributed Product Description, puts forward a realizable method to create the system of distributed database using Oracle9i, convert the 3 - D simulation model into XML and store it into database through JDBC, and gives the definition of XML Schema document which it will conform with.
