General concepts of Access DBMS

Modern civilization desperately needs constant processing and preservation of large volumes of various data. Also, there is a constant need to monitor the impact of their changes on other information arrays. It is most convenient to organize all these processes in the form of a database. A popular tool for such an organization can be a popular Access DBMS program.

What is DBMS

Various data are accepted to be presented and stored in the form of tables. It often happens that in several tables there is information that is related to each other in some way. The totality of such interdependent tables is a database.

In order to be able to fully operate on the data from the database, you must also execute queries. And in order to facilitate the filling of the database with the initial information, customized forms are usually used. To automate the process, in some cases you have to additionally apply macros. The combination of the database and additional tools forms a system called DBMS, a database management system. An example can be Foxpro, Oracle, Microsoft Access.

Main functions of the DBMS

DBMS Access performs the following important functions:

- implementation of necessary actions with data and formulas;

- establishing links between tables and data sets;

- Ability to add requests.

The entire set of tools, which is available in the MS Access database, is intended for full-fledged servicing of the two main directions during the operation of the information system. This is the organization of designing and modifying the structure of the database and various necessary manipulations with the data.

Main differences of Access database

From many other control systems, which are used by programmers to automate the work with databases, the Access database is easy to learn. Since this platform is Russified, and also has a standard interface for all programs of MS Office interface, even inexperienced users will not feel any inconvenience during its development.

At the same time, Access is a full-fledged program for managing data arrays with all the necessary attributes. The created system can be used not only on a separate computer, but also in a branched local network.

Access Features

This program makes it possible to create source objects in the form of tables with fields of various types, for example, numerical, text, graphic, even OLE fields.

Moreover, communication between the tables is provided, while cascading data updating and cascading deletion, if necessary, are supported.

All basic data operations are performed, such as entering, browsing, storing, updating, sorting, filtering, sampling. Also indexing on the selected fields is performed, control of the entered information.

When fields are filled, calculations using various formulas can be used.

DBMS Access is a convenient and understandable program that has all the capabilities of such professional applications.
