试验数据统一访问技术研究与实现

Research and Implementation of Test Data Unified Access Technology

为实现航天产品研制过程中试验数据的有效共享与重用,需要在试验数据管理(TDM)系统中提供一种易于与异构应用、分布式资源进行数据交互的试验数据统一访问接口。针对TDM系统中试验数据共享、重用与展示需求,采用Web Service技术实现了系统与Java/C++语言开发的异构应用及客户端程序的集成,并以试验数据三维可视化控件集成为例对应用效果进行介绍。通过基于Web Service技术的数据统一访问接口,实现异构系统进行信息交互,使开发工作无平台与技术上的限制,异构系统间的集成更加便利,数据安全得到有效保障。

In order to implement test data＇ s effective sharing and reusing during the development phase of aerospace products, unified data access interfaces which are easy to transfer data between system and other heterogeneous resources need to be provided in the Test Data Management System （TDM）. According to the demands of data sharing, reusing and demonstration, the we used Web Service technology to implement the integration of heterogeneous system developed by Java/C＋＋ language and client-side application. In addition, a case which integrates system with 3D visualization control was presented as implementation effect in this paper. Using the unified data access interface based on Web Service technology, we implemented the data interaction between heterogeneous system. The system can be developed without platform and technology constrains, interaction between heterogeneous system is more con- venient and data security can be ensured effectively.
