Typology of MIS

Main parts of Typology of MIS are given below:

1. Transaction Processing System (TPS):

TPS processes the transactions and produces reports. In business, it may be probable that 1000 transaction may be made. So, TPS automates this process. You see barcode scanner. With this, we can just scrutinize the code of product and sale entry without human intervention is recorded by computer system at any point of sale.

2. Decision Support System (DSS):

It is the system which is helpful for decision making. DSS is not just used in planning but with this we also analyze the information. Salary information system is MIS because it provides the information of different employees' salaries. But DSS provides advance information like in which scheme, the user gets more tax rebates. In DSS, there are different types of formulas which are useful for calculation of this.

3. Executive Support System (ESS):

ESS is used for specific requirement of manager at top level. For example, company needs advance information for knowing the personality of manager. At that time, ESS will be applied in organization.

4. Business Expert System (BES):

This system creates artificial intelligence of human being and suggests different decision for business.
