摘要: 为实现基于全要素模型的空间信息关系数据库存储,首先对全要素模型(Full Feature Model,FFM)及其关系类型进行了分析,阐述了FFM与关系模型映射的内容;然后提出了一种FFM与关系模型的关系解析映射方法,给出了基于图论的具体映射过程与算法;最后实现了表达FFM的复杂图与关系模式之间的转换,并给出了具体实例;为空间信息基于关系数据库的集成与共享等奠定了基础。

Abstract: As to store spatial information in relational database based on full feature model (FFM), firstly, FFM and its relation types were analyzed, and the content of mapping between FFM and relational model were expounded. Then, a relation-decomposing mapping method between FFM and relational model was put forward, and its mapping procedure and algorithm was put forward based on graph theory. Finally, the transformation between complex graph and relation schema was realized, and a visualized example about the mapping was offered. All these will found the base to integrate and share spatial information based on relational database.

Key words: full feature model, relational model, relation decomposing, mapping
