How would you distinguish data and information? Information and Knowledge? To distinguish between data and information you need to know what each one means. Data is the raw material for processing and refers to unprocessed information. Information is processed data. Information is that which informs that from which data can be derived. Information is conveyed either as the content of a message or through direct or indirect observation of some thing. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message. Information can be encoded into various forms for transmission and interpretation. Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning. Knowledge can refer to a theoretical or practical understanding of a subject. 3. Enumerate...

... Exercise 1 What is a Decision Support System? A decision support system is a processor information technique that assists with the company’s managerial endeavors. Decision support systems operate administration, business procedures, and product development of a company and assist to formulate conclusions, within a changing environment. Some of the responsibilities of a decision support system include the following: planning and organizing organization activities, provide data, conduct training programs, evaluate computer products, and provide support. Organizations depend on decision support systems to assist them with answering all business related questions and concerns. Decision support systems rely heavily on information, as the operations management technique uses the information to evaluate and examine. The Problem According to Watson and Carr (1987), “There are a number of organization structure alternatives for supporting decision support systems, and each alternative has its advantages and disadvantages” (p.84). Each organization has to be able to support the efforts of the decision support system, which consist of assisting clients to assess the computer products, supply access to information, and partake in product development. The issue of the “Organizing for Decision Support System Support: The End-User Services Alternative” article argues which division within a company is responsible for the decision support system. This determination has a considerable...

...Decision support systems are a lesson of computer-based information systems plus knowledge based systems which support decision making activities. Since there are numerous methods for decision-making, moreover, because of the wide range of dominions in which decisions are made, thus, the concept of decision support system (DSS) is very wide-ranging. A DSS may take several different formulae. In general, we can assure that a DSS is a computer system in order to aid for making decisions. A decision is an optimal among alternatives based on estimations, valuation and of the standard of those substitutes. However, supporting a decision means assisting employee working alone, or in a group gathers intelligence as teamwork and the best and appropriate for the organization. In addition, supporting the optimal making process involves backup, the appraisal and/or the comparison of alternatives. In practice, references of DSS are commonly references to computer applications that perform by means of supporting role. The decision support system has been well-defined in various ways by different scholars and managers. On contrary, others define a DSS rather mainly is "a computer-based system that aids the process of decision making." For instance, Turban expresses exactly as "an interactive, flexible, and adaptable computer-based information system, specially developed for supporting the solution of a non-structured management problem for improved decision making. It utilizes data, provides...

...TYPES OF INFORMATION SYSTEMS An information system is a collection of hardware, software, data, people and procedures that are designed to generate information that supports the day-to-day, short-range, and long-range activities of users in an organization. Information systems generally are classified into five categories: office information systems, transaction processing systems, management information systems, decision support systems, and expert systems. The following sections present each of these information systems. 1. Office Information Systems An office information system, or OIS (pronounced oh-eye-ess), is an information system that uses hardware, software and networks to enhance work flow and facilitate communications among employees. Win an office information system, also described as office automation; employees perform tasks electronically using computers and other electronic devices, instead of manually. With an office information system, for example, a registration department might post the class schedule on the Internet and e-mail students when the schedule is updated. In a manual system, the registration department would photocopy the schedule and mail it to each student’s house. An office information system supports a range of business office activities such as creating and distributing graphics and/or documents, sending messages, scheduling, and accounting. All levels of users from executive management to nonmanagement employees utilize...

...Evolution of Information Systems (Relevant to AAT Examination Paper 8: Principles of Auditing and Management Information Systems) David Chow FCCA, FCPA, CPA (Practising) This article discusses the evolution of information systems, levels of management decision-making and information systems that enhance the value of information. Students are encouraged to understand the reasons for the development of an information system and its replacement; these will help you identify the benefits and limitations of each type of information system. From EDP to MIS Until the 1960s, the role of most information systems was simple. They were mainly used for electronic data processing (EDP),purposes such as transactions processing, record-keeping and accounting. EDP is often defined as the use of computers in recording, classifying, manipulating, and summarizing data. It is also called transaction processing systems (TPS), automatic data processing, or information processing. Transaction processing systems – these process data resulting from business transactions, update operational databases, and produce business documents. Examples: sales and inventory processing and accounting systems. In the 1960s, another role was added to the use of computers: the processing of data into useful informative reports. The concept of management information systems (MIS) was born. This new role focused on developing business applications that provided managerial end users with predefined management reports that...
