Today, most IT expenditure in organizations involves enterprise wide systems that support various business functions. This expanding use of information systems has created many challenges for the business community.
What is an Information System?
In a general sense, the term Information System (IS) refers to a system of people, data records and activities that process the data and information in an organization, and it includes the organization’s manual and automated processes.
In a narrow sense, the term information system (or computer-based information system) refers to the specific application software that is used to store data records in a computer system and automates some of the information-processing activities of the organization. Computer-based information systems are in the field of information technology.
The discipline of business process modeling describes the business processes supported by information systems.
There are various types of information systems, for example:
Transaction Processing Systems (TPS), Decision Support Systems (DSS), Knowledge Management Systems, Database Management Systems (DBMS), and Office Information Systems.
Critical to most information systems are information technologies, which are typically designed to enable humans to perform tasks for which the human brain is not well suited, such as: handling large amounts of information, performing complex calculations, and controlling many simultaneous processes.
Information Systems careers:
Information technologies are a very important resource available to executives. Many companies have created a position of Chief Information Officer (CIO) that sits on the executive board with the Chief Executive Officer (CEO), Chief Financial Officer (CFO), Chief Operating Officer (COO) and Chief Technical Officer (CTO).The CTO may also serve as CIO, and vice versa. The Chief Information Security Officer (CISO), who focuses on information security within an organization, normally reports to the CIO.
Someone who studied information systems can works as a:
• Systems analyst
• IT Project manager
• Web developer
• IS Manager
• Systems developer
• Systems tester
The employment in this field is growing very fast, The 2006 Occupational Outlook by the US Bureau of Labor Statistics report states:
“Employment of computer systems analysts is expected to grow much faster than the average for all occupations through the year 2014 as organizations continue to adopt and integrate increasingly sophisticated technologies.”
Studying Information Systems:
Information Systems is a major found in many universities all around the world, studying information systems develops a range of skills, which are used in the stages of analysis, design and implementation for varied information systems. These include the organizational, inter-organizational and technological issues in e-business systems, the development of web-based systems, and the portfolio of information systems needed to support large-scale organizations.
The Bachelor of Computer Information Systems is a bachelor’s degree, similar to the Bachelor of Computer Science, but focused more on practical applications of technology to support organizations while adding value to their offerings. In order to apply technology effectively in this manner, a broad range of subjects are covered, such as communications, business, networking, software design, and mathematics.
Most IS bachelor programs have these subjects in common:
- Principles of Information Systems.
- System Analysis and Design.
- System Design and Implementation.
- Computer subjects such as: (Networking, Database, HCI, Programming…. Etc)
- Business subjects such as: (Management, MIS, Accounting, Marketing….. etc)
