Component Information System

Stair (1992) explains that the computer-based information systems (CBIS) in an organization made up and the following components:

1. Hardware, the hardware components to complement the activities of data entry, data processing, and output data.
2. Software, the program and instructions given to the computer.
3. Database, a collection of data and information organized in such a way that is easily accessible information system users.
4. Telecommunications, the communication link between users of the system with computer systems together into an effective network.
5. People, the personnel and information systems, including managers, analysts, programmers, and operators, as well as be responsible for system maintenance.

Procedures, ie procedures which include strategies, policies, methods, and regulations in using computer-based information systems.

While Burch and Grudnistki (1986) argues, the system consists of information and components above referred to as a building block, the block input, a model block, output block, technology block and control block. As a system, the six blocks of each interacting with one another to form a single unit to achieve its goals.

1. Input block. Represent the input data into the information system. Input here including methods and media to capture data that will be inserted to form the basic documents.
2. Model block. The block is made up and the combination of procedures, logic, and mathematical models that will manipulate the data input and data stored in the database in a particular way to produce the desired output.
3. Block Exodus. Products and information systems is that the output quality information and documentation that is useful for all levels of management as well as all users of the system.
4. Block Technology. Technology is a tool box (tool-box) in information systems. The technology used to receive input, run the model, storing and accessing data, generate and send the output as well as help control and overall system.
5. Blocks Database. And Database is a collection of related data with each other, is stored in the computer hardware and software used to manipulate it.
6. Control Block. Controls should be designed and implemented to ensure that things that can damage the system can be prevented or if already there mistakes can be directly addressed quickly.

Meanwhile, in the opinion of Davis (1995), consisting of management information systems and the following elements:

1. Computer hardware.
2. Software, which comprises the general system and software, application software, and application programs.
3. Database.
4. Procedure.
5. Operating officer.
