摘　　要：为支持异构数据库的数据同步与交换,提出了基于内存和文件的数据传输方法,介绍了其中涉及的关键技术和实现过程。在允许采用同一应用实例的条件下通过数据同步的内存传输技术,可实现数据的高速同步。对于只能通过文件传输实现同步的情况,提出了使用大文件传输技术,通过文件网关和断点续传技术实现文件同步的安全性与可靠性。该方法在电力调度业务系统数据同步与交换中,取得了很好的应用效果。This paper proposes a data transfer method based on memory and file to support the data synchronization and exchange between heterogeneous databases, and introduces the key technologies and realization process. The memory transmission technology is used to realize high speed synchronization when the same application instance is designed for the sender and receiver. Large file transfer technologies of file gate and broken-point eontinuingly-transferring are employed to guarantee the security and reliability of file synchronization when only file transfer is allowed for synchronization. This method has good application effects in the data synchronization and exchange of the power dispatching system.
