What Is Information System
Information systems, such as a coffee vending machine , a manufactured goods factory, a vehicle, a document file, our spine, etc. In the case of coffee or beverage machines, we can analyze their operation to better understand the system concept. The coins enter the system, its value is compared with that of the selected beverage (objective of the system) and if both values are equal, the beverage is issued.
The Concept of The Information System
With regard to the systems themselves there is a broad consensus as to the characteristics they must have and ways of acting, however the same does not happen with the concept of information system , of which there are many definitions, nuances and schools. Anyway, speaking in general terms, we can say that an information system is a set of components that interact with each other to achieve a specific purpose, which is to meet the information needs of that organisation. These components can be people, data, activities or material resources in general, which process the information and distribute it properly, seeking to meet the needs of the organisation .
The primary objective of an information system is to support decision making and control everything that happens in it. It is important to note that there are two types of information system, formal and informal; the former use solid structures such as computers as a means, the
latter are more artisan and use older media such as paper and pencil or word of mouth. The study of information systems emerged as a sub discipline of computer science, with the objective of streamlining the administration of technology within organisations. The field of study was progressing to become part of the higher studies within the administration.
Information Systems Can Be Classified in Various Ways
From a business point of view, information systems can be classified in various ways. There are, for example, management information systems (in order to resolve conflicts in companies), transaction processing systems (which are responsible for handling information in the context of commercial exchanges), executive information systems (for managers ), decision support systems (analyze the different factors that make the business to decide what direction to take), office automation systems (applications that help in administrative work) and expert systems (which emulate the behaviour of a specialist in a specific domain).
According to the authors Landon and Landon, professors of Business Administration, an information system is an organism that collects, processes, stores and distributes information. They are essential to help managers keep their company tidy, analyze everything that happens through it and create new products that put the organisation in a good place. This definition is one of the only ones that expresses the requirement that an information system has components , although it does not specify what they should be, possibly because it tries to encompass all possible variants of this concept.
It should be noted that the concept of information system is usually used as a synonym for computer information system , although they are not the same. The latter belongs to the field of study of information technology and can be part of an information system as a material resource. In any case, it is said that information systems deal with the development and administration of an organisation’s technological infrastructure.
