Computer Based Information System

What is an information system???

Computer Based Information System (CBIS) is the object that is constructed or developed to meet the needs of users in the running of the organization of information. CBIS is a data processing system to produce high quality information and is used as an aid in decision-making to solve Problems, Opportunities or Command, while the quality information is information that is proportionate and adequate means professional and responsible in providing solutions.
The key to this CBIS is a Computer System (CS), and Information Systems (IS) and who take advantage of this CBIS is a user that acts as a Management System (MS), so that the relevant terms in the CBIS including:
Computer Systems (Computer Systems), includes:
a. Hardware, computer hardware that can be captured directly by human senses, such as CPU, monitor, printer etc.
This device includes the main device for inclusion (Input Device), the processing unit (Processor Unit) and for presentation (Output Device) and other supporting devices for storage (Disk), control (Controller), communication etc.
b. Software, computer software that can not be captured directly by the human senses in the form of electronic signals, serving to connect the hardware to the brain ware so that communication can occur.
These devices form a program or data stored in a memory, such as programming languages, application packages, operating systems etc.
c. Brainware, human devices that use or run the computer to meet the needs of the information in solving the problem. These devices include operator, programmer, analyst, installers, etc. communication specialist.

Information Systems (Information Systems), includes:
1. Inputs, activities involving income (including capture and entry) to the data is ready to be used in the SI. This input in the form of energy that is captured and received by using the Hardware, Software and Brainware accordance with certain forms of energy are included, this energy is data that has been prepared in such a way in a database system.
2. Models, the activity to form or process data that has been entered through a process of logical, mathematical and algorithmic. This model in the form of data processing by using the Hardware, Software and certain Brainware expected based on shape model, and this model is the processing that has been prepared in such a way in a programming or existing applications.
3. Outputs, activities relating to the presentation of the results of the energy that has been processed in such a manner modeled as expected, the shape is often known as Information. The output of this new form of energy generated by using the Hardware, Software and Brainware accordance with certain desirable forms of new energy, new energy there that can be used and nothing is wasted, while that may be utilized in the form of reports are arranged in a file system (archieval system).
4. Database, which activities that regulate, coordinate and manage the data to be processed, is being processed or has been processed, can be used either directly or that still can not be used this database is set up with the hardware, software and certain brain ware that is generated in the form of a hierarchical database technology, Network , Relationship, Object Oriented, Multimedia, web and data warehouse. Besides, it also generated a database architecture in the form of a personal database, the central database (sentralisir) and the distribution database (desentralisir).
5. Technology, engineering activities that help in entering, processing, presenting, storing, and controlling the entire processing of data in information systems.
6. Control, to control the activity of the entire process that goes against errors, constraints, disaster (destruction, theft, viruses), etc., good control of the totality (organization, documents, software, and physical security of data and communications) and specific control (input, processing and output).

Management System (Management System), includes:
a. Functional Management, personnel involved in the management functions such as marketing, production, finance and human resources known as 4 (four) pillars of the company.
b. Level Management, personnel involved in the decision-making levels of management consisting of top-level charge of planning strategies, Middle level in charge of management control and the Low level in charge of operational management.
