IT 1105 Information Systems and Technology Enterprise systems Transaction Processing Systems (TPS) - is an organized collection of people, procedures, software, database and devices used to perform and record business transactions. Enterprise Resource Planning (ERP) - is a set of integrated programs that manages the vital business operations for an entire multisite, global organization.
IT 1105 Information Systems and Technology Information and decision support systems Management Information Systems (MIS) - is an organized collection of people, procedures, software, database and devices that provide routine information to managers and decision makers. It focuses on operational proficiency and MIS typically provide standard reports. It was developed to produce managerial reports periodically. Decision support system (DSS) - is an organized collection of people, procedures, software, database and devices that support problem specific decision making. The focus of DSS is on making effective decisions.
IT 1105 Information Systems and Technology Decision support system (DSS) A DSS can include • a collection of models used to support a decision maker or user (model base) • a collection of facts and information to assist in decision making (database) and • systems and procedures (user interface or dialogue manager) Also Software called the database management systems (DBMS) is used to manage the database and software called model management system (MMS) to manage the model base.
IT 1105 Information Systems and Technology Other Systems use the DSS approach A group support system includes the DSS elements just described as well as software called groupware to help groups make effective decisions. An executive support system also called executive information system helps top level managers make better decisions. An executive support system can assist with strategic planning, top level organizing and staffing, strategic control and crisis management.
IT 1105 Information Systems and Technology Specialized Business Information Systems Knowledge management systems (KMSs) - an organized collection of people, procedures, software, database and devices, to create, store, share and use the organization’s knowledge and experience. Artificial Intelligence - Robotics is an area of artificial intelligence in which machines take over complex, dangerous, routine, or boring tasks. Expert systems - give the computer the ability to make suggestions and functions like an expert in a particular field, helping enhance the performance of the novice users. The expert system allow organisations to capture and use the wisdom of the experts and specialists.
IT 1105 Information Systems and Technology Virtual Reality and Multimedia Virtual reality - is the simulation of a real or imagined environment that can experienced visually in three dimensions. Multimedia - is a natural extension of virtual reality. It can include photos, images, the manipulation of sound and special 3 D effects.
