What is information system?

An information system is a set of many closely interrelated elements, forming a whole. These elements are extremely diverse, creating a huge data block and constituting a certain area of ​​information systems. Can be mentioned as the university system, the communication system, the transportation system …

The components of an information system in general can be physical elements such as machines, equipment, personnel, departments … At the same time, the information system also includes non-material elements. such as amount of data, processing rules, procedures, information collection process …

In the past, when computer technology was not developed, information systems were mainly collected and stored with pen, paper, documents, and file storage cabinets. Today, almost all data of information systems are updated into hardware or software stored on computers and managed automatically.

What are the characteristics of the information system?

In addition to understanding what the concept of an “Information System” is, you also need to know the features of this system. Specifically:

Information systems are stored on computers

With the strong development of the technology field globally, the information system is built and stored on the basis of modern technology. Such as supercomputer systems with huge memory, hardware and software to manage masses of data …

Information systems are branching

In fact, a large information system consists of many sub-branches, called a branch information system. So what is the ramifications of information systems?

We can understand as follows: Each sub-branch in the system has an intimate relationship, is connected and interacts with each other. Each time the manager updates data on any one sub-branch, it will indirectly affect the data system of the remaining branches, as well as change the general information system data. Also, when performing data access of the information subsystem, the manager needs to pay attention to the mutual relationship between the branch systems.

Information systems subject to change

An information system is a type of system with a “flexible” and flexible structure. The reason to say so is because they are always changing, always evolving day by day, hour by hour, even every second.
