采用powerdesigner 9.5 设计数据库，vb 利用其ole功能开发生成代码

萝卜波产品经理 2004-12-28 12:12:20

// 想法，
//将数据库表和字段信息导出，生成数据库表到java代码的映射
//一些字段再设置“不能为空”“email”。。。校验，生成客户端js校验代码，和服务器端每个表校验java代码.....
//生成structs相关代码
//预期目的，...
//工作正在进行中，完善之后和大家分享

//本人广州，05毕业研究生，有招人的吗，期待伯乐

J2EE只是Java企业应用。我们需要一个跨J2SE/WEB/EJB的微容器，保护我们的业务核心组件（中间件），以延续它的生命力，而不是依赖J2SE/J2EE版本。
