Requirements for information processing in the information system:
- information should be complete and sufficient;
- information should be provided in a timely manner;
- information should be reliable;
- information processing should be economical;
- information should be adaptive to the changing information needs of users. users.
Classification of management information systems
Classification of MIS is carried out according to the most characteristic features (attributes) that are inherent in information systems. For example:
- By the nature of representation and logical organization of information:
Factual IS are designed for accumulation and storage of data in the form of multiple instances of one or more types of structural elements (information elements) reflecting information on some facts, events, etc., separated from other information.
A single information element of documentary IS is an input document.
document. When creating an information base, structurization is not performed or is performed in a limited way.
Geographic information systems contain separate information objects linked to a common electronic topographic base (electronic map). - By functions and tasks:
Reference IS that provide users to obtain certain classes of objects (telephone numbers, addresses, literature, etc.). For example, card catalogs, electronic directories, software or hardware electronic notebooks, etc.
Information retrieval IS, designed to search and retrieve information on different search images.
Calculation IS, designed to process information according to certain calculation algorithms.
Technological IS, designed to automate the entire technological cycle or its individual components of the production or organizational structure.
