| 摘 要： | 数字校园的建设必然涉及到各种数据资源的整合、集成与交换。讨论了数字校园下的“信息孤岛”现象,采用目前使用广泛的XML技术来解决异构数据库间的数据交换。在此基础上研究了数据库与XML间的模式映射和基于矩阵的数据类型映射,并提出了利用交换规则解决异构数据交换中的逻辑异构问题,从而较好地解决了数字校园建设中的“信息孤岛”问题。

| Abstract: | The construction of digital campus is always related to the conformity,integration and exchange of different data resources.In respect to the "information island" phenomenon,this paper realizes data exchange among heterogeneous databases by XML technology which is widely applied nowadays.It proceeds to probe into the pattern mapping between database and XML,and the mapping of data type based on matrix.Solving the problem of heterogeneous logic by exchange rules,we succeeded in resolving the "information island" phenomenon on the construction of digital campus. |

| Keywords: | digital campus heterogeneous database data exchange XML exchange rule |
