基于数据集的数据交换技术研究

在数据交换技术的发展中,数据交换技术的实现往往作为研究的重点,而忽略了数据交换过程中数据才是核心。在数据交换过程中数据的生命周期的研究成为重点。因此,介绍了一种以数据集为中心的数据交换模式,采用元数据来记录数据信息在数据交换的整个生命周期中的流转状态。分析了数据交换技术,其关键是如何保持数据的完整性和一致性。设计了基于XML中间件的数据映射规则,满足源数据和目标数据的完整性。将数据集引入到数据交换中。

Research on Data Exchange Technology Based on Datasets

In the development of data exchange technology,the research was focused on the realization of the data exchange technology , and ignored that data was the core in the data exchange. Research of the data in the life cycle in the data exchange process become the core in this paper. Therefore,this paper introduces the research on data exchange technology based on datasets ,uses the metadata model to record the circulation state of data in the whole life of the data exchange; analysises the data exchange technology, the key is how to maintain the integrity and consistency and designs the mapping rules based on XML, meets the integrity of the data between the source database and target database. The innovation points of this paper is that datasets are used in the data exchange.
