Computer-Based Information Systems or Computer Based Information System (CBIS) is a data processing system into a high quality information and can be used as a tool to support decision-making, coordination and control as well as the visualization and analysis.
Data is a description of things and events that we hadapi.Jadi in essence, is the fact that the data describing an event and is a real unity that will be used as a basic ingredient information.
Information is the result of processing the data into a form more useful for those who accept that describes a real events and can be used as a tool for decision making.
System is an entity, whether abstract or concrete, which consists of several components that are interlinked with each other. Objects that have no connection with the elements of a system is not a component of the system.
Information System is a system of generating information. With the integration between subsystems owned, information systems will be able to provide quality information, precise, fast and accurate in accordance with management who need them.
Information Systems' computer-based "means that the computer plays an important role in an information system. In theory, the implementation of an Information System does not have to use a computer in its activities. But in practice it is not possible highly complex information systems that can work well if the absence of a computer. Information systems are accurate and effective, in fact, is always associated with the term "computer-based" or processing information based on the computer.
2.What is the role of information specialists to the development of CBIS?
Business application of computers in business has been greatly developed along with the development of information technology in the world. The stages of development, namely: 1. At the beginning of the data (electronic data processing - EDP)With the technology and keydriven punched card bookkeeping machine, and companies generally ignore the information needs of managers.2. On Information (Management information system - MIS)With the introduction of calculators that allow processing of more and faster. It is oriented to the concept of using computers as a management information system (MIS).3. In decision making (decision support system - DSS)DSS is a different thing from the SIM. DSS is a system aimed at producing information for a specific problem to be solved and decisions taken by managers.4 In the communication (office automation - OA)OA komunikais facilitate and enhance the productivity of managers and office workers through the use of office equipment. OA has been developed covering a variety of applications such as remote conferencing, voice mail, e-mail, electronic calendaring, facsimile transmission and desktop publishing.5. In Consultation (artificial intelligence / expert systems - AI / ES)The basis of the AI is a computer can be programmed to perform some logical reasoning is the same as humans.
People who are responsible for the development and maintenance of computer-based systems, namely:
1.Systems Analyst
2.DataBase Administrator
3.Network Specialist
4.Programmer
5.Operator
Here is the system followed the CBIS development life cycle:
1.Planning Phase
2.Phase Analysis
3.The design phase
4.Implementation Phase
5.Stage of Use
CoverCBIS is a system that helps people dala process data into more useful information, especially for the data base within the company.
