数字化校园环境下异构数据映射维护关键技术分析

Key technologies analysis of heterogeneous data mapping maintenance in Digital Campus environment

异构数据的集成问题是数字化校园建设首要解决的问题之一,而其关键在于通过映射技术建立异构数据之间的一致性。映射失效检测是数据集成中维护系统有效运行的重要基础,是进行映射维护的关键。根据学校数据集成特点,通过引入模糊聚集算子,提出了一种映射失效检测的方法。

Heterogeneous data integration problem is one of the most pressing issue in Digital Campus. The key lies in building heterogeneous data consistency through mapping technology. Mapping failure detection is maintained in data integration an important foundation for the effective operation of the system, also the key to Map Maintenance. According to the features of school data integration, through the introduction of fuzzy aggregation operators, proposed a method of mapping failure detection.
