Information systems or ICT systems are important in every company. They support the business processes or parts thereof. Information systems can be divided into a number of groups: administrative and production information systems, integrated information systems, administrative information systems, documentary information systems.
What is an information system
An information system is a system that processes information, which is done through workers, resources and actions. So an information system is made up of different elements, and these are the data (input data, stored data from previous periods and output data), people, resources, actions and the process itself. Most information systems have been developed to support business processes or parts thereof. To guide these processes, the data must be well structured. There is a wide choice of these types of systems for every terrain. These information systems can be divided into a number of groups;
Administrative and production information systems
An administrative information system supports the administrative activities in a company such as invoicing, accounts receivable, payroll processing, etc. Administrative information systems often contain a lot of similar data on which the same operations must always be performed. In short, it is routine work. Routine work is relatively easy to record in computer programs. That is why automation in the administrative field has taken off enormously.
Integrated information systems
The disadvantage of using various information systems is that data storage is spread across different systems. Data exchange from one system to another is a major problem. Customer data maintained on different systems often differs from each other if both do not use the same data store. Increasingly, the information systems written for various activities are being combined into a massive package that supports as many business processes as possible. Also known as an integrated information system.
Administrative information systems
An administrative information system serves to support the management and control of business activities. The data for these types of systems largely comes from a company’s administrative information systems. In order to manage and manage the activities, you have to make decisions and answer questions such as: should staff be hired? Does the minimum stock of a certain item need to be adjusted?
Documentary information systems
A documentary information system is increasingly used in business processes with an intensive document flow, such as insurance companies and government institutions. A documentary information system supports the management and maintenance of documents, books, magazines, articles, images and sound. A documentary system helps the user search for the desired information in a quick manner, including through the use of keywords. Such systems are therefore used in companies that process many documents. You need a lot of storage space for storage, a documentary system takes up much less space since everything is stored digitally. Data that is found relevant in relation to the company is entered into the information system. Entering data into an information system creates a positive core response that benefits the company. By entering data, information is added, information provides further knowledge and knowledge leads to action in the company. This may involve identifying and confirming a working employee so that he or she can function in the company up to the same employee’s salary.
The cycle when the information systems are applied correctly
Data that you receive from the information systems can also help you manage your company, because through the processed data you can, for example, determine the standard of production. The following figure clearly shows what kind of cycle follows if the information systems are applied correctly.
The ICT possibilities in the field of communication and information are expanding, becoming increasingly accessible and nowadays it is indispensable. Nowadays (and certainly in the future), ICT is part of communicating and providing/disseminating information. Why is it that ICT has come to play an increasingly important role in the field of communication and information? This is due to the fact that communication and information through ICT (technologies and software) is faster, more efficient and simply much easier.
Examples of ICT in the field of Communication
You can send e-mail (digital letters) anywhere in the world where you have an internet connection on a computer. And after a few seconds it has already arrived in the other person’s digital mailbox.
You can call landlines and mobiles anywhere in the Netherlands without a wire or socket because your mobile phone connects via satellites and draws energy from the portable (disconnecting) battery. Calling to or from abroad is also possible.
Examples of ICT in the field of Information
ICT in the field of information improves the quality of the service that a company provides. An information system improves the speed of data retrieval by entering some keywords. Because searching for data becomes much faster, the company’s service improves, which causes customers to stay with that company, which gives that company a better competitive position.
ICT in the field of information saves space. Spaces that were once used as repositories of paper data on employees, production, profits, etc. can now be stored on a computer that takes up little space. The remaining spaces can be filled by productive processes.
