Definitions of Management Information System:
“The study of MIS is not about the use of computers, it is about the provision and use of information relevant to the user. Computers are one - albeit important - means of producing information and concentration on the means of production rather than the needs of the user can lead to expensive mistakes." (Lucey  pg 195)
“A system to convert data from internal and external sources into information and to communicate that information, in an appropriate form, to managers at all levels in all functions to enable them to make timely and effective decisions for planning, directing and controlling the activities for which they are responsible.” (Lucey  pg 2).
MIS is a planned system of collecting, processing, storing and disseminating data in the form of information needed to carry out the functions of management.

It mainly accumulates process, treasures and retrieves the data. This is evaluates and distributes the information.
There are Five attributes’ which play a major role in MIS these mentioned below which s should be “useable”
Timeliness: The entity which is maintains MIS should accomplish in affording and categorizing the accurate and current information to relevant users. It should be designed in such manner that it would be accelerate the information, with in less period of time. It should accumulate the data, edit it and abstract it.
