【Abstract】 Through the study of the problems such as the synchronization method of heterogeneous databases, the synchronization strategies of databases, the process of schema mapping,the way of data capture and data communication and so on,a data synchronization mechanism based on the operating system task plan to achieve timing data update between heterogeneous databases is put forward,to solve the problem of ‘information island’ in the construction of digital campus.更多还原
