摘　　要：为了提高管理信息系统的开发效率,适应用户界面的多变性,增强系统的可修改性和维护性,框架结合MVC和MDA的优势,使用XML描述业务流程、界面组件、数据组件、连接组件、业务组件;动态生成用户界面;创建业务流程、数据组件及连接组件的实例;采用Petri网来控制业务流程,协调各种组件完成业务逻辑处理。开发人员可在几乎"零编码"的情况下完成业务逻辑开发,极大地提高了开发效率,方便了系统变更与扩展,增强了系统可维护性。During the development of the management information systems, multi-user operating easily lead to the issues of long live transaction of human- computer interaction, but database transaction processing mechanism can not solve this problem. In this article we have designed a long transaction strategy which based on the connect components. It resolves the issue of long transaetion＇s right that locking or unlocking the resources by adopting a flag and the timestamps. By this way we can avoid the possible misuse of data effectively, ensure the quality of work and enhance the consistency of the database.
