Data Model Support Distributed System Integration
Song Zheng · Jisuanji fangzhen · 2009
Data integration is one of the key questions of realizing distributed system integration. Based on the data model, the organization of level and the flexibility of the expression, a spatial integration data model (SIDM) was offered, relationship of data in different type was described, and the characteristic of different item in a data type was described through spatial data model, the conception and algebraic description were afforded in object of spatial data to take a meta-data play, a criterion is advance for algebraic operation of data integration, and data integration of distributed system integration is supported effectively.
