传统企业信息系统存在结构灵活性差、复用率低、开发周期长等缺点,为此在引入模型驱动架构和企业建模方法的基础上,提出了基于模型驱动架构的企业信息系统开发框架,在这种框架下,首先建立企业的业务需求模型,经过模型诊断、优化,建立起设计模型,以此模型为基础,逐步建立起面向过程的计算无关模型、面向对象的平台无关模型和面向模式的平台相关模型,最终转化为软件代码.
To solve existing problems in the Enterprise Information System (EIS) software such as poor flexibility,low reuse rate and long development cycle, an EIS software development framework based on MDA was proposed. In this framework, the first step is to build enterprise business requirement model through model diagnosing and optimizing, the business model is build, and process oriented calculation independent model, object oriented platform independent model and pattern oriented platform specific model built are constructed. At last the PSM is transformed to software code.
