Abstract

In this recent technological world, it is necessary that we get accustomed to all types of advanced technological techniques. In the process, we are becoming more aware about database and information system. But what is database system information? The Database Management System which works through the storing of data can be used any time. The importance of database and information Systems in modern business is inevitable. In this chapter, we define Information Systems by its categories of Information System, type and the usefulness for efficient Information System. Then, we will proceed to explaining the management of information systems by taking a short look at its history and list some of its domains of application. After that, we define the relation between Information Systems and database. Finally, we will explore the problem of storage and some issues related to information systems and databases.

The information System (IS) provides additional network hardware and software it is used by people and organizations to assemble, filter, process, create and distribute data. (Jessup and al., 2008).

  • Information Management: Finds theoretical and practical solutions for the collection of data (Denning & Peter, 1999) and the analysis of information in an area of business. This function including the application (Coy & Wolfgang, 2004) and implementing programming tools productivity of the business, data mining, and decision support (Hoganson & Ken, 2001).

  • Communications and Networking: Deals with telecommunication technologies (Davis, and al., 2004).To study various business models and related algorithmic processes within a computer science discipline Information Systems bridges business and computer science using the theoretical foundations of information (Hoganson & Ken, 2001) and computation (Khazanchi and al, 2000).

An information system is a work system whose activities are devoted to processing information. It’s a special kind of work system; in which humans and/or machines perform work (processes and activities) using resources to produce specific products and/or services for customers (Alter, 2003)

It inter-relates with data systems on one hand and activity systems on the other. It can be considered a semi-formal language which supports human decision making and action. Information systems are the primary application that incites the study for managerial informatics. (Beynon-Davies, 2009)
