MIS is the superintendent provides the report, provides the enterprise the recent situation as well as the historic record. This system main localization is aims at in the enterprise, for control function and so on level plan, check and decisionmaking serves, provides the data generally by the lower level handling of traffic system. MIS will be able the actual enterprise39。s control check, for high level also can provide certain information. The management information system frame by four parts: Information source, information processor, information user and information superintendent. The information source is the information production place。Decision models can be used to support different stages in the decisionmaking process. “Intelligence” models can be used to search for problems and/or opportunities. Models can be used to identify and analyze possible solutions. Choice models such as optimization models maybe used to find the most desirable solutionWhen all access to any use of database is controlled through a database management system, all applications utilizing a particular data item access the same data item which is stored in only one place. A single updating of the data item updates it for all uses. Integration through a database managem
