However, due to the differences of time, period and visual angel, these systems are built and put to use alone according to a certain work demand, thus leading to “an isolated island of information”. They also have difficulties in the exchange of data, low sharing of data and are inconvenient to use, so they are poor at organizing the overall information promptly and effectively which have a good function in a company’s manufacturing and operating policy. In order to solve these problems, the author thinks that it needs a systematic the information resource planning, carrying out the applied software programs according to the unified function models, data models and data standards. This thesis is to set forth the methods and practice of the plan of the information resources.
