Enterprise Information Resources Planning And Data Flow Visualization Tool Design And Realization

Information Resource Planning is the basal project of an enterprise' s information system construction, which origin is Information Engineering Methodology.It emphasizes particularly on strategic data planning and absorbs a lot of experiences from Information Resource Management and Data Adiministration.It also combines practice of many large or medium domestic information construction projects.Then it has developed a complete set of system including theory, method and tools by the principle of science, brachylogy and practicality.Information Resource Planning software tools wholly sustain planning phases from requirement analyze to system modeling.They are the important sustainable part in Information Resource Planning.They provide an unified planning platform, which makes every planning group not work independently but also cooperate and share planning fruit on net.At the same time tools solidify the criterion and standard of Planning, which make system analysts and operation users work more canonically and help them to do complex data-processing with computer and consistent understand them.The paper pays attention to whole and strategic data planning of an enterprise.It firstly.expatiates on the system of theory, method and tools.It also detailedly introduces two typical planning c, especially discuss the basal action and important meaning of Information Resource Planning in telecom enterprise.During the development of tools, it is evident that data flow diagram'tool is very necessary for rapidly carding the complex outer and inner data flow of function area, and for solving the problem of researching and analyzing the complex information flow toward the whole enterprise in deed, and for offering important basis and reference for building the information system's logic model of entir enterprise.The paper especially designed and realized the visual tool of data flow based on Information Resource Planning system.In face visual tool is a strategic data-analysis tool and an important organic part of Information Resource Planning tools.It emphasizes wholly conformity with planning repository and brachylogy and practicality.It last discusses the realistic meaning to engineering method of Information Resource Planning from handwork to anto/computer-aid drawing.It puts forward optimizing and improving the engineering method in order to ensure exact and precise implement.
