| 摘 要： | 为了在Internet网上共享产品数据,基于Java语言实现了STEP标准数据读取接口SDAI.该实现包括几个部分:EXPRESS信息模型向Java语言的映射,Java SDAI会话模式的实现和JOS/Part 21文件、JOS/STEP数据库两个映射.基于该Java SDAI接口的STEP应用系统,可采用Browser/Server三层体系结构,客户端用户通过通用的Internet网浏览器即可操作异地的STEP产品数据,该Java SDAI接口既与Part 21文件又与关系型数据库(SQL Server)相连接.通过一个演示实例,对Java SDAI的优、缺点进行了总结.

| Abstract: | For integrating product data on the Internet, the STEP SDAI(Standard Data Access Interface) based on Java language is implemented. This system includes these models: mapping of EXPRESS model to Java Language, application program interface according with SDAI session schema,and two converters, one is JOS to Part 21 file, the other is JOS to STEP Database. Base on this Java SDAI interface,STEP application can adopt Browser/Server architecture, using a current Browser(IE or Netscape), users can access the STEP data on Internet. Optionally, this Java SDAI interface support STEP Part 21 file or RDBMS. At last, a demo based on Java SDAI is developed. |
