摘要
提出模型驱动的信息集成方法,在数据元模型统一的基础上实现企业数据交换。统一数据模型以元-元模型为基础,采用UML中的标识符进行系统建模,然后通过数据流交换格式把元模型中的内容转换成XML文件。
In this paper, a method of Model Driven Architecture (MDA) is introduced, and enterprisedata exchange is implemented based on a unified metamodel. The core of MDA is metaobject facility, which is described by notations of UML. In the procedure of MOF building,the Platform-Independent Model is established firstly, then platform-specific model isbuilt referring to application environment. Stream-based model interchange format isadopted in transferring content from MOF to XML formatted file. In this transferring, thegeneration rules of DTD and XML documents is defined by extended backus naur form.
