Why Should I Study Information Systems? � Homo Conexus: � You are the most connected generation in history. You practice continuous computing. You are surrounded by a personal, movable information network. Your personal information network is created by constant cooperation between: the digital devices you carry; the wired and wireless networks that you access as you move about; Web-based tools for finding information and communicating and collaborating with other people. You can pull information from the Web and push your ideas back to the Web.

THE INFORMED USER YOU! An informed user is a person knowledgeable about information systems and information technology, IT skills open many doors because IT is so widely used.

WHY BE AN INFORMED USER? � Reasons why you should be an informed user: You will benefit more from your organization’s IT applications because you will understand what is “behind” those applications. You will be in a position to enhance the quality of your organization’s IT applications with your input. Even as a new graduate, you will quickly be in a position to recommend the IT applications that your organization will use. Being an informed user will keep you abreast of both new information technologies and rapid developments in existing technologies. You will understand how using IT can improved your organizations performance and teamwork as well as your own productivity.

Information Systems as a functional area � Other names: � Deals with: ◦ ◦ MIS Department Information Systems Department Information Technology Department Information Services Department “Planning for - and the development, management, and use of - IT tools to help people perform all the tasks related to information processing and management” (p. 12)

Definition of Information System According to Rainer and Cegielski: Information Systems collect, process, store, analyze, and disseminate information for a specific purpose. The purpose of IS: to get the right information to the right people at the right time in the right amount and in the right format to support business process and decision making.

Definition of Information System � IS – a set of interrelated components working together to collect, retrieve, process, store, and distribute information for the purpose of facilitating planning, control, coordination, analysis, and decision making in business organizations

DEFINITIONS Information technology (IT) �Relates to any computer-based tool that people use to work with information and to support the information and informationprocessing needs of an organization.

y. Technology – the means by which data is transformed and organized for business use: ◦ ◦ Hardware Software Database Telecommunication y. People – the users of IS y. Organization -- a collection of functional units working together to achieve a common goal

Goal of Information Systems: “economically process data into information or knowledge” Fig_1 -2

COMPUTER-BASED INFORMATION SYSTEMS � Binary code, the foundation of information and knowledge is the key to making complex decisions. Data Items. Elementary description of things, events, activities and transactions that are recorded, classified and stored but are not organized to convey any specific meaning. Information. Data organized so that they have meaning and value to the recipient. Knowledge. Data and/or information organized and processed to convey understanding, experience, accumulated learning and expertise as they apply to a current problem or activity.

CBIS � � Computer-based information systems are information systems that use computer technology to perform some or all of their intended tasks. The basic components of computerbased information systems are: Hardware is a device such as a processor, monitor, keyboard or printer Software is a program or collection of programs that enable hardware to process data. Database is a collection of related files or tables containing data. Network is a connecting system (wireline or wireless) that permits different computers to share resources. Procedures are the set of instructions about how to combine the above components in order to process information and generate the desired output. People are those individuals who use the hardware and software, interface with it, or uses its output.

TYPES OF INFORMATION SYSTEMS �Transaction processing systems (TPS) � Management information systems (MIS) � Decision support systems (DSS) � Expert systems (ES) � Communications systems � Collaboration systems � Office automation systems

APPLICATION PROGRAMS � An application (or app) is a computer program designed to support a specific task or business process. (A synonymous term is application program. ) The collection of application systems in a single department is usually referred to as a departmental information system (also known as a functional area information system). For example, the collection of application systems in the human resources area is called the human resources information system (HRIS).
