Information systems and technologies are important components of successful enterprises and organizations Information systems refer to the sharing of common functions under the same direct management control.
Information systems and their trends. Information systems are people, data, processes, data presentations, and arrangements that support the information technology we need on a day-to-day basis. The system consists of hardware, software, information, data, applications, communications and people. It is in fact a technically implemented medium for recording, storing and communicating language expressions and drawing conclusions from such expressions. Information technology
Types of information systems
Information systems can be divided into two basic forms
1. Operational Support
It is further subdivided into
o Process Control Systems
o Transaction Management Systems (TPS)
o Enterprise Collaboration Systems
o Decision support systems
o Execution support systems (ESS)
o Management information systems (MIS)
Information Systems Development Tools
The steps involved in the development of information systems are:
Analysis, Feasibility Studies, System Design, Testing, Implementation, Documentation
Information Systems Trends :
It is generally accepted that information is an important commodity for today's successful organization. Today, modern business organizations are using computerized information systems to get the information they need. However, with the rapid development of technology, the main problem is how to effectively use such information systems, and its management may sometimes be unpredictable in order to effectively help improve the entire organizational structure and make the most of it.
It seems obvious that information systems have played an important link before the advent of the Internet. Thus, for example, the possibilities offered by information systems strongly influence the way managers can exercise control and thus constitute an important factor in large enterprise organizations and their geographic extension. This is also true of the Government and its statistical agencies. The recent integration of computer networks and electronic data interchange has facilitated the establishment of common databases and policies between governments and accelerated earlier development. It also creates new possibilities for enterprises, such as enabling organizations to develop new organizational practices (eg, in a timely manner).
However, the role of information systems in the organization is turning to supporting business processes rather than individual functions. The focus is on the customer, not the inbound program. Businesses are changing faster and faster
This poses a challenge to existing information systems, which are often inappropriate and can not meet these needs.
To ensure that information systems provide services when they are needed, and their failures do not cause catastrophic disasters, their reliability efficiency becomes paramount. Imagine what happens when the banking system fails due to some critical failure in the system, or when the health care information system provides the wrong advice to the patient.
Not to mention that our lives are already under the control of computer systems, but their reliability and efficiency have become very important
Implemented in the Present World Of the application of information systems. For example,
1. Sales analysis, production performance and cost trends
2. Product pricing, earnings forecasts and risk
3. Sales and Inventory Handling and Accounting Systems
4. Geographic Information System
5. Medical Information System
6. Petroleum Information Systems
Petroleum Refining Systems
8. Power Generation Systems
Iron and Steel Production Systems
