INTRODUCTION

The basis for accounting, control and planning are all sorts of file cabinets, registers, lists, etc. They gradually accumulate and updated. With a large amount of information search and compilation of necessary information, is done by hand, it is rather time-consuming process.
With the advent of computers and the use of their data processing became possible to automate the solution of many information - reference and settlement problems.
Initially, for the accumulation and storage of information on computer use local arrays (or files), with each of the key functional tasks to create their own original files and Scoring information. This led to a significant duplication of data, updating complicated, complicates the problem of related tasks.
Gradually, with the development of computer software came the idea of \u200b\u200ba control system that allows you to collect, store, and update related data on a range of tasks, such as the automation of accounting at the company. These ideas were embodied in the database management system (DBMS). DBMS does not interact with local and interconnected arrays of information, called data bases. With the advent of personal computers are the most popular database processing means tabular information. They are a tool of design of banks when processing large amounts of information.
Software for working with databases used in personal computers for quite some time. Unfortunately, these programs were either elementary storage controllers and did not have application development tools, or were so complex and difficult that even well-versed in computers, people avoided working with them as long as it gets full, user-centric applications.
Microsoft Access - is a functionally complete relational database management system. It contains all the tools you need for defining and processing data, and to manage them when working with large volumes of information. As for ease of use, Microsoft Access has made a real revolution here, and many to create their own databases and applications are turning to him.
A database management system provides you with the ability to control the structure and the job descriptions of their data and work with them and the collective use of this information. DBMS also significantly increases the capabilities and facilitates the cataloging and management of large volumes of stored data in multiple tables. Database includes three main types of functions: definition (structure and job description), data processing and data management. All these features are fully implemented in Microsoft Access. In practice, as a rule, you must solve the problem with using spreadsheets and word processors. For example, after counting or analysis of data necessary to present them in the form of a specific shape or pattern. As a result, the user has to combine the software to achieve the desired result. In this sense, all significantly simplify the possibilities offered by Microsoft Access. It is proposed to consider these possibilities.
