1. Information Systems

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).

It includes a diversity of disciplines such as: (1) the analysis and design of systems, (2) computer networking, (3) information security, (4) database management and (5) decision support systems. (Archibald, J.A., 1975).

• •

  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)
