Abstract
To meet the needs of data exchange in the information system of Tsinghua University, In this paper, the authors designed and realized a data exchange platform to be implemented in digital campus with improvements in multiple aspects: application of Extract, Transform, and Load (ETL) technology to accomplish data exchange in large quantities of heterogeneous databases, utilization of Enterprise Service Bus (ESB) technology to accomplish real-time data exchange in small quantities of heterogeneous databases, and implementation of authorized management to accomplish data exchange in homogeneous databases. The developed data exchange platform has been operating steadily and produced little impact on the server and business system, exhibiting great potential in digital campus applications.
