Understanding Information Systems
Information system is a collection of hardware, software, brainware, procedures and or rules that are integrally organized to process data into useful information to solve problems and make decisions.
The information system is an integrated and complementary processed data unit that produces output in the form of images, sounds and text.
An information system is a group of components forming a system that has a link between one component and other components aimed at producing information in a particular field.
In information systems the classification of information flows is needed, this is due to the diversity of information needs by information users. The criteria of the information system, among others, are flexible, effective and efficient.
Information system is a collection of related sub-systems that form a component which includes input-process-output related to information management (data that has been obtained so it is more useful for the user).
An information system (SI) or information system (IS) is an arrangement of people, data, processes, and interfaces that interact to support and improve some of the daily operations in a business, including supporting problem solving and management decision-making needs. and users who are experienced in their fields.
An information system is a collection or set of components that relate and support the functions of gathering, processing, storing and distributing information.
The results of this process are used by management as a basis for organizational decision making. In addition, a good information system can also help in terms of analyzing and visualizing problems in the creation of new products.
Basic Concepts of the System
The basic concept of the system there are two approaches namely the emphasis on the procedure and emphasis on its components.
The system definition that emphasizes procedure is: a network of interrelated procedures, gathered together to carry out an activity or to accomplish a certain goal.
A procedure is: a sequence of clerical operations, usually involving several people in one or more departments, which is implemented to ensure uniform handling of business transactions that occur.
Other definitions of the procedure are: the exact sequence of stages of the instruction that explains what needs to be done, who does it, when to do it and how to do it.
The system definition that emphasizes more on the components / elements are: a collection of elements that interact to achieve a certain goal.
System characteristics, namely: have components, system boundaries, the environment outside the system, connectors, input, output, processor / process, and goals or objectives.
Classification of the system from several points of view as follows:
The system as a natural system and man-made system.
System as an abstract system and a physical system.
The system as a particular system (deterministic) and an uncertain system (probabilistic)
The system as a closed system and open system.
Basic Concepts of Information
Within the organization is very important in managing key resources such as labor and raw materials, but now information is also an important resource that must be managed.
Decision makers understand that information is not just a byproduct of an ongoing business, but also as a filler for business and a critical factor in determining the success or failure of a business.
Information is like blood flowing in the body of an organization. So that information is one of the main forms of resources in an organization that is used by managers to control the company in achieving its goals.
The definition of information is: data that is processed into a form that is more useful and more meaningful for those who receive it.
Data is: reality that describes a real event and unity. Or data are: real-world representations representing objects such as humans (employees, students, customers), animals, events, concepts, circumstances etc., which are recorded in the form of numbers, letters, symbols, text, images, sounds or combinations thereof.

Information cycle: Data that is still raw material must be processed to produce information through a model. The model used to process the data is called the data processing model or known as the data processing cycle (information cycle).
