Geographic Information System (GIS), a special field of Information Technologies (IT), is an information system has wide application in many professional fields, such as bank, traffic management system, pipe layout, weather forecast and so on. It plays a more and more important role in the information age we are now creating. For customer' s requirements oriented designing, traditional GIS software meet more and more irresolvable problems, can neither completely meet the demands of applications, nor keep pace with the mainstream of software technologies, and all of these make it affront much more challenge. Components GIS, briefly called ComGIS, is a new generation of GIS based on Components Software and Component-Based Development technologies.First of all, the essay discusses the development GIS software technologies , the challenge which traditional GIS faces, the actuality and trends of ComGIS. It is also noted that the essay expatiates ComGIS and software technologies concerning ComGIS, and analyzes the application of these technologies in GIS;and according to the space specific characteristic distingushing quality in the Resources of Telecommunications Exchange Equipment, puts forward to use component-based development technologies to design the Resources of Telecommunications Exchange Equipment Management Information System based on component technologies, so as to meet the demand of a telecom enterprise in infrastructure designing, maintenance management and decision-making etc..In this essay, we discuss and analyze the solution of GIS realization based on our systematic research on ComGIS appliance, with the guideline of systematism theory, and in virtue of the principle and method of systemsengineering, and the Object-oriented technology and the COM technology as well as according to the requirement and satisfying the demand.Finally, the essay introduces the Resources of Telecommunications Exchange Equipment Management Information System which integrate with BorLand Delphi and Maplnfo MapX . The content includes design of object, structure, function and database. In addition, the author expatiates on the design of special database and attribute database in detail, and introduces the application outlook of the Resources of Telecommunications Exchange Equipment Management Information System.The innovation of this essay is following the software industry development trends tightly, integrating the systematism theory, COM technology and GIS perfectly, and put forward to provide GIS application development some profitable research, both setup a solid basic of developing GIS from a professional tool to a personal utility, and present a frame of developing GIS which has much more high-tech functions. So as a conclusion, we can say that this method has wide application outlook and much great value in engineering.
