The structure of an information system is represented by the totality of its individual parts, which are called subsystems. The latter are functional and providing. The functional part consists of a number of subsystems that solve specific tasks of planning, control, analysis, accounting and management of objects. To ensure the normal operation of the main part of the information system, it must include a supporting subsystem.
The general structure of an information system is a complex of subsystems, the purpose of which may be different. So, providing are:
- informational;
- technical;
- mathematical and software;
- organizational;
- legal.
Information Support Subsystem
The IO subsystem is a unified system of classification and coding of information, a unified documentation system, a scheme of information flows that circulate in organizations and a methodology for organizing databases.
The structure of the information system provides this element to ensure the timely formation and issuance of reliable information for management decisions.
In order to correctly organize information support, you need the following:
- clearly present the goals, objectives, and functions of the entire information system;
- accurately determine the movement of information and present it in the form of a scheme of information flows;
- improve the workflow process;
- use the current classification and coding system;
- own a methodology for creating information-logical models of relationships;
- create arrays of information on data carriers.
Technical Subsystem
Technical support is a set of technical means for ensuring the operability of an information system and documentation for them.
Hardware is represented by computers of any models; devices for the collection, accumulation of information, as well as its processing, transmission and organization of output; data transfer devices; office equipment and devices for automatic reading of information; operational materials, etc.
The subsystem of mathematical and software IP
The structure of the information system provides for the existence of a subsystem of mathematical and software, which is a combination of mathematical methods, algorithms, and programs for fulfilling the goals and objectives of functioning.
Software tools include tools for modeling management processes, mathematical programming, etc.
Software is developed software products with technical documentation for them.
Organizational support
This subsystem is a combination of methods and means aimed at regulating the use of technical means and the interaction of workers among themselves during the development and industrial operation of IP.
The functions of the subsystem are to analyze the current type of control and identify tasks that require automation; setting tasks for execution on a computer, justification of their effectiveness; the development of managerial decisions to the structure of the organization, methodologies for solving problems that increase the effectiveness of the management system.
Legal Support Subsystem
It represents the legal norms that determine the creation of an information system, its legal status. The main objective of legal support is the strengthening of the legitimacy of the system, so it is composed of laws, decrees, instructions, decrees, etc.
The architecture of an information system is defined by a concept that defines the model, structure, functions and relationships of components.
The concept of "information system" includes that of traditional architectures. This file-server, client-server, transition to a three-layer and three-layer architecture.
