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
