Abstract:
The paper presents the designing business systems using data structures specific to economic flows. In the study of the process of designing information systems, the notion of system is essential. A system represents a set of interdependent elements (components) between which a dynamic interaction is established, based on pre-established rules, with the aim of achieving a certain objective. According to systems theory, any economic organism is a system. Depending on how detailed the analysis is, a system has many characteristics, such as, each system accepts a number of inputs, processes the information provided by them, and sends the results to the outputs and from there, to the environment in which the system evolves. The boundaries of the system separate it from the environment in which it manifests itself. Through interfaces, a system communicates with the environment. A system exists only in the environment that contains it and will interact with it through the data and information received. A system is made up of components. These, also called subsystems, between which various relationships are established, can be formed from indivisible component elements or from groups of aggregated elements. For example, the financial-accounting department of a company is formed by the aggregation of people who perform functions of this nature, as is the human resources management department. The design of subsystems is very important because, if the system as a whole no longer functions correctly, its repair should be possible by simply replacing the subsystem that caused the failure. The limitations of the system refer to the constraints imposed by its parameters (for example, storage capacity or speed) according to which the system must function in order to achieve the purpose for which it was created.
