%X The process of manufacturing tools by human being has experienced three stages: material tools, energy tools and information tools. Information tools compose information system in the form of systems. Information systems are mapping of entities and relationships between them in real world. It composes of objects and relationships, objects can be classified into Facility Objects and Domain Objects, Domain Objects are inheritance and extension of Software Facility Objects, Soft ware Facility Objects are generalization and abstraction of Domain Objects. Information systems are digital model of the real world; the core problems of IT development are modeling the real world. The development of GIS extends the current object model,to construct a Unified Object Model with spatial property. It makes IT modeling the real world more effectually,information is organized and analyzed in the spatial framework.it will improve the unification of spatial and temporal recognition in IT and promote the development of knowledge tools. Current GIS technology is suitable for resolving the macro spatial problems, Micro GIS must be developed to solve the micro spatial problem.
