Field information system (IS) is a combination of processes, hardware, trained personnel, software, infrastructure and standards designed to create, modify, store, manage and distribute information to suggest new business strategies and new products. It leads to efficient working practices and effective communication to make better decisions in an organization. In recent decades there has been a significant evolution in the function of the information system. It is changing day by day. It includes data processing, management reporting, decision support, executive support, knowledge management and e-business. Ultimately, IS (information system) is evolving drastically in different fields. Many companies use different perspectives to make their work easier and now IS (information system) has improved the systems into artificial intelligence computing systems which can also be used to predict business performance.

Get an Original Essay Evolution of Information Systems: In the 1950s the role of IS was primarily to perform tasks such as transaction processing, record keeping, and accounting. IS has been mainly used for electronic data processing (EDP). EDP ​​is described as the use of computers to record, classify, manipulate and summarize data. It is also called information processing or automatic data processing. Transaction Processing System (TPS) was the first computerized system developed to process business data. TPS collects, stores, modifies, and retrieves an organization's daily transactions. Typically, TPS computerizes or automates an existing manual process to enable faster processing. Examples of TPS outputs are cash deposits, automatic teller machines (ATMs), payment orders, and accounting systems. Later, this was moved to MIS (Management Information Systems). Basically, MIS provides reports that typically confirm transaction processing activities and the information establishes the data in a format that an individual can quickly review. In DSS (Decision Support Systems) In this personal era computers were introduced with the introduction of PCs the distribution of computers is easily accessible. This new role for information systems in providing ad hoc interactive decision-making support to managers and other business professionals is called Decision Support Systems (DSS). He later moved to ERP (enterprise resource planning), a specific form of strategic information system that incorporates all components of an organization including manufacturing, sales, resource management, human resource planning, and marketing. Current trends in information systems: Now the development has moved towards the application of artificial intelligence (AI) techniques to enterprise information systems. Expert systems (ES) and knowledge management systems (KMS) interconnected with each other. Expert systems (ES) are a computer system that mimics the decision-making ability of human experts. For example, systems that make financial forecasts, diagnose human diseases, and plan routes for delivery vehicles. Knowledge management system (KMS) is an IT system that stores and retrieves knowledge to support the creation, organization and dissemination of corporate knowledge within the enterprise. ES uses data from knowledge management systems to generate desirable information system output, e.g..
