INFORMATION SYSTEM (IS)

First and what is system? A system is a set of element that works together, such as input, output, processing mechanism and feedback. For instance in an organization (for example restaurant) how the information is passed out from customers, to the cook till to the top manager of the restaurant. This people to complete their task, they use an application which is called CBIS (computer base information system).basically there are so many IS  such as  TPS, DSS, ESS, MIS, OAS …but mostly there are classified in this to category : support decision making ex: MIS and support business operation ex: TPS, OMS,  ECS

Now let talk about IS components. there are seven components first and first people who operates the system, secondly the hardware, thirdly the software, fourth application software, programming language software,  procedures which are  strategies rules or methods used to manage the IS telecommunication and lastly the database which is the place where the information is stored.

There are there types of planning in almost every organization: strategic, tactical, and operational. The top manager will use the strategic planning and ESS to manage and set goals and missions for the company. While the Middle manager, will use tactical planning and MIS to support decision making. the MIS produces reports whereby  The input of MIS is the output of TPS. The low manager will use TPS and the operational planning to monitor, collect, keep records and process data generated from business transaction. Each department in a company must have its own TPS.
