Modern civilization urgently needs constant processing and preservation of large volumes of various data. Also constantly there is a need to track 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 convenient tool for such an organization can be a popular Access DBMS program.
What is a DBMS?
Various data are usually presented and stored in the form of tables. It often happens that several tables contain information that is somehow related. The collection of such interdependent tables is a database.
In order to be able to fully operate with data from the database, it is also necessary to fulfill requests. And in order to facilitate the filling of the base with initial information, specially designed forms are usually used. To automate the process in some cases, you have to additionally use macros. The combination of the database and additional tools forms a system called a DBMS - a database management system. An example would be Foxpro, Oracle, Microsoft Access DBMS .
DBMS main functions
Access DBMS performs the following important functions:
- implementation of the necessary actions with data and formulas;
- establishing relationships between tables and data arrays;
- the ability to add queries.
The entire set of tools available in the arsenal of the MS Access DBMS is intended for the full-fledged servicing of two main areas during the functioning of the information system. This is the organization of the design and modification of the database structure and various necessary data manipulations.
Key Features of Access DBMS
From many other control systems that are used by programmers to automate working with databases, Access DBMS is easy to learn. Since this platform is Russified, and also has a standard interface for all MS Office programs, even inexperienced users will not feel any inconvenience during its development.
At the same time, Access is a complete 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 an extensive 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, numeric, text, graphic, even OLE fields.
Moreover, communication between tables is provided, while cascading data updates and cascading deletions are supported if necessary.
All basic data operations are performed, such as entering, viewing, storing, updating, sorting, filtering, retrieving samples. Also, indexing by selected fields, control of the entered information is carried out.
When filling in the fields, calculations using various formulas can be used.
Access DBMS is a convenient and intuitive program that has all the capabilities of such professional applications.
