基于xUML的MDA开发数据仓库设计与实现

Design and Implementation of MDA Development Data Warehouse Based on xUML

在分析目前主要的模型驱动架构MDA构建数据仓库的基础上,根据WTADSS数据仓库的体系结构,提出了基于xUML的MDA开发方法,采用ETL负责将WTADSS中不同的数据进行相应的处理并将其集成到数据仓库存储库中,以达到数据格式的统一。经过实测验证,该方法不仅在初始阶段能够对系统进行测试,而且也能够通过返回的测试结果对前期的建模进行修改,减少系统的出错率。

The main methods of building data warehouse with model driven architecture are analyzed.According to the architecture of the WTADSS data warehouse,a development of MDA based on xUML is presented.The different data of the WTADSS is processed by ETL,those data is finally integrated into the WTADSS data warehouse to achieve the reunification of data format.The test show that the method not only can easily be tested the system in the inceptive phase,but the model can be self-modified by the result of the testing, which can reduce the rate of mistakes.
