Nowadays, the level of information and knowledge management is not fully controlled in most companies. Information systems create support for business processes in order to optimise them, based on experience from the processes within similar businesses. Today's information systems are used in data management or information management. Only a few of them manage information processing in the field of tactical and strategic planning, and almost none manage processing in the field of gathering, distributing, and sharing knowledge in a company. It can be said that investments in IT do not guarantee a successful way of managing information and knowledge in a company. The main task of management support applications is to analyse current data and, based on their analysis from different perspectives, give managers the opportunity to identify nonstandard situations in a company. The process of obtaining data, information, and knowledge from large files is not only a technological problem but also a managerial problem. Therefore, the set technologies are being used as tools to fulfil the needs of information. From a managerial point of view, the goal of the process is to obtain as much relevant information and knowledge as possible to be able to solve the problem.
