Introduction

Information technology - a very broad definition, which falls under a number of selected technical means and methods of working with information. But as a rule, in the process of information people have to deal with well-defined sequence of interactions associated with different means. Depending on the scale of time (up to long-term operational and strategic objectives) and the scale of operations (from one job to the whole company) can be detected are different and sequence, and to manage them need different methods. Methods vary in the degree algorithms and rationalization. The most efficient set of algorithmic methods and tools to work with information is information system. Information system is an interconnected set of tools, methods and personnel used for storage, processing and delivery of information. Information systems are a different purpose and scope. Also, information systems differ in the extent of the coverage areas of the company (whether they take into account only the accounts and also the storage, finance, manufacturing, etc.) (O'Brien, p. 41-43). However, all information systems have a number of properties that are common to them:

IP designed to collect, store and process information. Thus, the basis of any information system is the means of storage and data access.

IP designed for the end user who is not a specialist in the field of computer technology. From this it follows that the EC should include the client-side applications that provide an intuitive interface (O'Brien, p. 41-43).

Information systems are factual and documentary. The former include IP, designed to find a clear answer to a request for a unique solution of tasks. Conventionally, factual IP divided in turn into information-reference systems, information retrieval systems and operational data . System operational data processing tasks such as production management, accounting and t.p.Po scale IP can be divided into:

Board.

Network.

IP enterprise (O'Brien, p. 41-43).

Documentary information systems designed to solve problems that do not provide an unambiguous answer to the question. Some systems are a mixed type of factual and documentary IP. In most cases when you need a comprehensive system for storing, processing and retrieval of information, the procedure implementation is very time-consuming and laborious (O'Brien, p. 41-43). Despite the fact that the process of developing an enterprise of such innovations as the EC is very complicated, if the process is completed and then spent the resources are always compensated by the fact that:

EC automates the application of mathematical methods to solve management problems.

IP is at least partially exempt employees from routine work.

IP minimizes the likelihood of errors during transmission, or processing information.

EC reduces the volume of documents on paper.

IP enhances workflow.

EC reduces the cost of production of goods and services (O'Brien, p. 41-43).

In the narrow sense of the information system referred to only a subset of the components of the IP in the broadest sense, including databases, database and specialized software applications. IP in the narrow sense, considered as a hardware-software system designed to automate the end-user focused activities, which provides, in accordance with the logic inherent in her treatment, the possibility of ...
