This paper discusses building theories and approaches of relational mode for attributive database of Geographic Information System (GIS). The relational mode decomposition of geographic entities is a key problem for applied designs of attributive database in database mode planning of GIS. On the basis of characteristic analyses for attributive database of GIS, the author expounds decomposing expressions of relational mode for geographic entities, as well as restrictive properties in decomposition dependence properties. An intricate relational mode of geographic entities is decomposed into a group of simple attributive relational sets in decomposition expressions of relational mode. Meanwhile, in order to not lose information in decomposition process and to uphold the integrated restrictions of geographic data, the author also discusses restrictive conditions for joining information without loss in decomposition of relational mode, and explains restrained factors for maintaining function dependence in mode decomposition.
