基于J2EE的SDAI实现方法

SDAI Implementation Method Based on J2EE

提出了基于J2EE平台,采用多层结构的SDAI实现EAST(EJB Access to STEP data)系统,从而实现产品数据的共享。EAST系统以关系数据库作为SDAI的数据存储系统,基于EJB组件实现了可以多用户并发访问的SDAI对象层。还阐述了用EJB实现SDAI会话,访问远程repository以及SDAI数据字典和迟联编的实现机制。

This paper suggests EAST architecture implementation system,a based on J2EE-terrace and using multi-stratifica- tion SDAI to serve as the software infrastructure for product data sharing. EAST,taking relational database, as its data storage system has a standard access interface object layer implemented by EJB component supporting concurrect access, and a data dictionary to facilitate late binding, Implementation technologies of SDAI session, access to remote repository, data dictionary and late binding are also described.
