【正文】 tion system integration is also achieved through standards, guidelines, and procedures set by the MIS function. The enforcement of such standards and procedures permit diverse applications to share data, meet audit and control requirements, and be shares by multiple users. For instance, an application may be developed to run on a particular small puter. Standards for integration may dictate that the equipment selected be patible with the centralized database. The trend in information system design is toward separate application processing form the data used to support it. The separate database is the mechanism by which data items are integrated across many applications and made consistently available to a variety of users. The need for a database in MIS is discussed below. Need for a database The term “information” and “data” are frequently used interchangeably。 the overriding requirement is that there is an anizational function to exercise control. Utilization of Models It is usually insufficient for human recipients to receive only raw data or even summarized data. Data usually needs to be processed and presented in such a way that the result is directed toward the decision to be made. To do this, processing of data items is based on a decision model. For example, an investment decision relative to new capital expenditures might be processed in terms of a capital expenditure decision model. 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 solution In other words, multiple approaches are needed to meet a variety of decision situations. The following are examples and the type of model that might be included in an MIS to aid in analysis in support of decisionmaking。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。 The information user is the information user, carries on the decisionmaking using the information。s each kind of run situation, and using the past historical data forecast future, embarks the assistance enterprise from the enterprise overall situation angle to carry on the decisionmaking, used the message control enterprise the behavior, helped the enterprise to achieve its plan goal.
