The main kinds of information systems in business are described briefly below:
Executive Support Systems
An Executive Support System ("ESS") is designed to help senior management make strategic decisions. It gathers, analyses and summarises the key internal and external information used in the business.
A good way to think about an ESS is to imagine the senior management team in an aircraft cockpit - with the instrument panel showing them the status of all the key business activities. ESS typically involve lots of data analysis and modelling tools such as "what-if" analysis to help strategic decision-making.
Management Information Systems
A management information system ("MIS") is mainly concerned with internal sources of information. MIS usually take data from the transaction processing systems (see below) and summarise it into a series of management reports.
MIS reports tend to be used by middle management and operational supervisors.
Decision-support systems ("DSS") are specifically designed to help management make decisions in situations where there is uncertainty about the possible outcomes of those decisions. DSS comprise tools and techniques to help gather relevant information and analyse the options and alternatives. DSS often involves use of complex spreadsheet and databases to create "what-if" models.
Knowledge Management Systems
Knowledge Management Systems ("KMS") exist to help businesses create and share information. These are typically used in a business where employees create new knowledge and expertise - which can then be shared by other people in the organisation to create further commercial opportunities. Good examples include firms of lawyers, Accountants and management consultants.
KMS are built around systems which allow efficient categorisation and distribution of knowledge. For example, the knowledge itself might be contained in word processing documents, spreadsheets, PowerPoint presentations. internet pages or whatever. To share the knowledge, a KMS would use group collaboration systems such as an intranet.
Transaction Processing Systems
As the name implies, Transaction Processing Systems ("TPS") are designed to process routine transactions efficiently and accurately. A business will have several (sometimes many) TPS; for example:
- Billing systems to send invoices to customers
- Systems to calculate the weekly and monthly payroll and tax payments
- Production and purchasing systems to calculate raw material requirements
- Stock control systems to process all movements into, within and out of the business
Office Automation Systems
Office Automation Systems are systems that try to improve the productivity of employees who need to process data and information. Perhaps the best example is the wide range of software systems that exist to improve the productivity of employees working in an office (e.g. Microsoft Office XP) or systems that allow employees to work from home or whilst on the move.
The major categories of of information system plan are Management information system (MIS), decision support systems (DSS) and expert information systems (EIS). These three cover most of the operations carried out by a business.

what are the two categories of infomation technology?
Two categories of software are application software and system software. The Operating System and device drivers form part of system software.
There are two broad categories of software. These categories include system software, as well as application software. There are sub-categories to both of these types of software.
The terms MIS, information system, ERP and, information technology management are often confused. Information systems and MIS are broader categories that include ERP. Information technology management concerns the operation and organization of information technology resources independent of their purpose.
The peripheral nervous system is the nervous system outside of the brain and spinal cord. The two categories belonging to the peripheral nervous system are nerves and ganglia.
THE TPYES OF INFORMATION SYSTEM ARE THE VARIOUS AREA OR LINES OF INFORMATION SYSTEM WHILE THE EXAMPLES OF INFORMATION SYSTEM ARE THE SPECIALIZATION OF THE INFORMATION SYSTEM. AN EXAMPLE OF INFORMATION SYSTEM IS HMAN RESOURCES INFORMATION SYSTEM. J.O.ENADE

The main categories of information are education, past employment, hobbies and awards, experience and basic contact information. All other questions are usually asked in the interview.
IT is separated into two main categories (1) those which process information, such as computer systems, and (2) those which disseminate information, such as telecommunication systems.

Bar charts are probably the most frequently used charts and easiest to interpret. They are useful when comparing different categories of information or when ranking different categories of information.
Management Information System
An information system (IS) is a system designed to create, store, manipulate, or disseminate information. An example is your computer and browser which are part of the system used by the information system.
