Information Systems



In contemporary information-dependent society business firms, other organizations, and individuals fully rely on computerized information systems to manage their operations and to stay competitive. For instance, modern corporations rely on information systems to process financial accounts and manage human resources; municipal governments rely on information systems to provide basic services to its citizens; and individuals use information systems to study, shop, bank, and invest. As is seen, the term “Information System” bridges business field and computer science field and is defined by the encyclopedia Britannica as “an integrated set of components for collecting, storing, processing, and communicating information with the help of computers”. A well-designed information system rests on a coherent foundation, consisting of computer hardware and software, databases, telecommunications, networks, and of course people. In a broader sense, an information system is any combination of information technologies and people’s activities for supporting a company’s operations, management, and decision-making.

In order to function effectively information systems should be properly overseen by specially trained professionals. This overseeing usually falls into two major domains – Information Systems Management and Information Systems Administration. Information Systems Management involves application of information technology to organizational and managerial needs. It focuses on integrating computer systems with the aims and objectives on an organization. The strength of information systems managers lies in their ability to combine the understanding of business with the knowledge of information systems and technology to help organization compete more successfully or streamline current operations. Information systems managers utilize their business-based backgrounds to specify technology needs that benefit the organization. They analyze, design, develop, codify, implement, and manage state-of-the-art telecommunications, business, web-based and other computer-based information systems. They are also involved in decisionsupport, e-business, database development and data warehousing, development and use of client server systems, development of web-based technologies for electronic commerce and other business applications, and the design and management of telecommunications systems.

System administration encompasses all the essential aspects of computer maintenance and ensures that the computer system is in proper and usable order. Information systems administrators (or just sysadmins) typically have a broad range of responsibilities related to computer maintenance and repair. Sysadmins are on call when a computer system goes down or malfunctions, and must be able to quickly and correctly diagnose what is wrong and how best to fix it. They respond to the staff service calls and might be asked to set up a network, restore a crashed hard drive, configure a web server, or spec out and order desktop computers. They troubleshoota slow mail server, bring up a computer lab after a power outage, or mop up a flooded server room. Sysadmins are most frequently called upon to configure hardware, install and update software, set up and manage useraccounts, troubleshoot problems for users, schedule backups, maintain system security, and optimize system performance.
