摘要： 上下级单位以及同级单位之间的数据交换日渐频繁，这些单位采用的数据库多种多样，数据定义在语义、内容上存在冲突，需要交换的数据格式并不固定，随着业务的变化而变化。该文设计并实现了一个基于任务的数据交换系统，以端到端交换模型为基础，使其可以支持多种数据库之间数据交换和并发的数据交换任务，并通过配置满足交换内容变化的需求。

Abstract: Data exchange becomes more and more frequent between different departments. But these department’s databases are varied. They have different data formats, so there exist conflicts both in semantics and content. In addition, the data need to be exchanged are not fixed, possibly changes along with the service change. This paper proposes a data exchange platform, which takes the end-to-end exchange model as the foundation, and improves it to support the concurrent data exchange ability. It also can satisfy the unfixed format data exchange.

Key words: data exchange, exchange engine, data extraction, data load
