基于元数据的数据交换系统研究

Study on the Data Exchange System Based on Metadata

数据交换系统是服务数据交换需求的重要工具。在分析数据交换过程的基础上,提炼了异构数据交换的元数据模型,并以这些元数据模型为基础,设计实现了基于元数据的数据交换系统,大大提高了系统的适应性、灵活性、通用性和可扩展性,为大规模数据迁移和数据集成提供了基础支撑。

Data exchange service system is an important tool for the data exchange requirements. Based on the analysis on the data exchange process,refines the metadata model of heterogeneous data exchange, designs and implements the data exchange system based on metadata, it can greatly improve the adaptability, flexibility, versatility and scalability of the system, provides a basis to support for large-scale data migration and data integration.
