“Data” as an Information System Component (1) Distinct pieces of information, usually formatted in a specialway. All software is divided into two general categories: data and programs. Programs are collections of instructions for manipulatingdata. Data can exist in a variety of forms -- as numbers or text on piecesof paper, as bits and bytes stored in electronic memory, or as factsstored in a person's mind. Data is the plural of datum, a single piece ofinformation.In practice, however, people use data as both the singular and plural form of the word. ITU Management Faculty – MIS
“Data”as an Information System Component (2) The term data is often used to distinguish binarymachine-readable information from textual human-readableinformation. Some applications make a distinction between data files (files that contain binary data) and text files (files that contain ASCII data). (3) In database management systems, data files are the files that store the database information, whereas other files, such as index files and data dictionaries, store administrative information, knownas metadata.

Information System – Definition andPurpose • Aninformation systemconsists of components that support decision making and control, and helpwith analysis, visualization, and product creation. • An information system (IS) collects, processes, stores, analyzes, and disseminates information for a specific purpose “Application”. • Or Collects data, processes it into information then converts information into knowledge for a specific purpose. • A set of interrelated elements or components that collect (input), manipulate (process), and disseminate (output) data and information and provide a feedback mechanism to meet an objective. ITU Management Faculty – MIS
Information Systems Procedures - A combination of technical components - Built and used by people to collect, create, and distribute useful data - Used typically in organizational settings but are evolving for personal use ITU Management Faculty – MIS
What is an Information System? • An information system (IS) collects, processes, stores, analyzes, and disseminates information for a specific purpose. • Like any other system, an information system includes inputs(data, instructions) and outputs (reports, calculations). It processes the inputs by using Information technology and produces outputs that are sent to users or to other systems via electronic networks and a feedback mechanism that controls the operation. Feedback Input Processing Output Model of an information system ITU Management Faculty – MIS
Information System Is A System ITU Management Faculty – MIS
Input, Processing, Output, • Input • The activity of gathering and capturing data • Whatever goes into the computer • Processing • Converting or transforming data into useful outputs • Output • Useful information, usually in the form of documents and/or reports • Anything that comes out of a computer ITU Management Faculty – MIS
Input (n) Whatever goes into the computer. Input can take a variety of forms, from commands you enter on a keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input device. (v) The act of entering data into a computer ITU Management Faculty – MIS
Output (n) Anything that comes out of a computer. Output can be meaningful information or gibberish, and it can appear in a variety of forms -- as binary numbers, as characters, as pictures, and as printed pages. Output devices include display screens, loudspeakers, and printers. (v) To give out. For example, display screens output images, printers output print, and loudspeakers output sounds. ITU Management Faculty – MIS
Feedback • Feedback • Output that is used to make changes to input or processing activities • Feedforward • A proactive approach to feedback • Use for estimating future sales or inventory needs ITU Management Faculty – MIS

Management Information Systems • MIS is an organized collection of ; • People, • Processes, • Hardware - Devices • Software, • Databases, That are used to provide “information” todecision makers in all levels. • The vast majority of information systems are developed for and used by people in functional areas (e.g., manufacturing, human resources, accounting, finance and marketing). • To develop information systems that address the needs of the organization, MIS professionals must possess a solid mix of business and technical knowledge. They must understand; • organizational structures, • objectives, • operations (including processes and the flows of data between processes) • and the financial implications related to these factors. * MIS managers and professionals must stay up-to-date with evolving information technologies and have a solid foundation of technical skills to select appropriate technologies and to implement computer-based information systems.

Business Information Systems • The interactive relationships between the information systems and organizations, both technically and socially, and the business opportunities and challenges brought about by the BIS. • This describes information systems used to support the functional areas of business. “ Since the advent of the mainframe in the 1950s, companies have dreamed of “using computers to manage their businesses”. But early efforts came up short, with technology that was too costly or too clunky. Now, thanks to the Net and dashboards, those dreams are starting to come true. Forrester Research Inc. estimates that 40% of the 2,000 largest companies use the technology.” ITU Management Faculty – MIS

They don’t keep high inventory in their back rooms, saving on storage. When inventory in the store starts running out, the system notifies them to order more stock. Another business process that they use is sales. • They save money with their inventory, faster customer service, using self check, and eliminating baggers saves on labor cost. Technology also helps the cashiering with better computer systems there will be fewer errors. • The Information Systems Division (ISD) supports the world’s largest non-governmental database ITU Management Faculty – MIS
