Information systems and technologies have become a vital component of successful companies and organizations.

Information system means an interconnected set of information resources under the same direct management control that share common functionality. A system typically includes hardware, software, information, data, applications, communications, and people, while an information system is the arrangement of people, data, processes, data presentation, and information technology that supports our daily needs. Actually, it is a technologically implemented means to record, store and disseminate linguistic expressions, as well as to draw conclusions from said expressions. Computer technology is used to implement information systems.

TYPES OF AN INFORMATION SYSTEM

The information system can be divided into two basic forms

1. SUPPORT OPERATIONS

SYSTEMS

It is further subdivided into
monitoring

o Transaction Processing System (TPS)

o Business collaboration system

o Process Control System

2. MANAGEMENT SUPPORT

SYSTEM

It is further subdivided into the following

o Management Information System (MIS)

o Decision Support System (DSS)

o Executive Support System (ESS)

TOOLS FOR THE DEVELOPMENT OF AN INFORMATION SYSTEM

The steps involved in the development of an Information System are:

Analysis, Feasibility Study, System Design, Testing, Implementation, Documentation.

TRENDS IN THE INFORMATION SYSTEM:

It is generally accepted that information is a vital asset for the successful operation of today’s organizations. Today, modern business organizations use computerized information systems to obtain the desired information. However, as technology advances rapidly, the main problem is how an organization can effectively use such an information system, the management of which can sometimes be unpredictable, to effectively help the entire structure of the organization. organization to improve and make the most of it.

It seems quite obvious that information systems have played an important linking role even before the advent of the Internet. Thus, for example, the possibilities offered by Information Systems have strongly influenced the way in which managers could exercise control and therefore constituted an important factor in the organization of large companies and their geographical extension. The same is true for governments and their statistical apparatus. The recent integration of computer networks and electronic data exchange facilitated the creation of common databases and policies among governments, accelerating developments that had begun earlier. It also created new possibilities for business, for example by allowing companies to develop new organizational practices (eg just-in-time).

However, the role of information systems in the organization is changing to support business processes rather than individual functions. The focus is outward, toward customers, rather than inward, toward procedures. Companies are changing faster and faster.

This poses a challenge to existing information systems, which are often inappropriately structured to meet these needs. It also presents a challenge to the people who design, build, and use these systems, as they may have outdated assumptions.

To guarantee the services provided by information systems when needed and that their failure does not cause a catastrophic disaster, their reliability and efficiency become extremely important. Imagine what would happen when a banking system malfunctions due to some critical system failure or when a health care information system gives incorrect advice to patients.
It is not even an exaggeration to say that our lives are already under the control of computer systems, but their reliability and efficiency have become extremely important.

INFORMATION SYSTEM APPLICATIONS:

There is a wide range of information system applications being implemented in today’s world. To name a few like

1. Analysis of sales, production performance and cost trend.
reporting system

2. Product pricing, forecast return and risk
analysis system

3. Sales and inventory processing and accounting system

4. Geographic Information Systems

5. Health care information systems

6. Bank Information System

7. Oil Refining System

8. Power generation system

9.Steel production system
