基于元模型驱动异构数据统一建模的研究

Unified Modeling of Heterogeneous Data Based on Meta Model

随着互联网技术和web的迅速发展,现代企业间以及企业内部需要彼此将资源共享,但是不同企业间的数据源,结构,格式都是不大相同的。由此我们发现多源异构数据不能共享问题。于是提出了基于元模型驱动的多源异构数据的统一建模技术。该技术是通过建立数据字典的元模型对各类的异构数据进行统一的描述,然后通过数据的映射关系在建立起统一数据模型。最后该系统已经成功的应用在多源物品交易平台数据资源整合中。

with the rapid development of Internet technology and web, modern enterprises and enterprises need to share resources with each other, but the data sources, structures and formats between different enterprises are not the same. So we find that the problem of multi-source heterogeneous data can not be shared. Therefore, a unified modeling technology based on meta model driven multi-source heterogeneous data is proposed. The technology is to describe all kinds of heterogeneous data through the metamodel of the data dictionary, and then establish a unified data model through the mapping of the data. Finally, the system has been successfully applied to data resource integration of multi-source goods trading platform.
