A Database Management System or DBMS is a set of non-visible programs that manage the information contained in a database.
A Database Management System or DBMS is the Software that controls the installation of Database (database understood as the engine, not a specific database). In simple terms, it is a database installation on a specific server. This Database Management System can be various brands (SQL Server, Oracle, MySQL, MariaDB, etc.) and within each brand there are different versions or editions (Express, Standard, Enterprise for SQL server for example).

Characteristics:
This Software must compile with all the Specifications defined by the Codd Rules. In general, it must have the following characteristics:
- Redundancy
- Consistency
- Integrity
- Security
The database management system acts as the interface between the end users and the database itself. Thus, ensuring that other applications and users can access the data constantly. A DBMS consists of three main components, the database schema responsible for defining the logical structure of the database. The database engine that facilitates access to the data and the data itself. There are several types of database management systems. From small ones that run on PCs to large ones that run on data servers. Common examples include: Microsoft Access, MySQL and Oracle.

The key functions of a DBMS
Many of the functions of a database manager are contained in the brief definition made. As we have pointed out, a DBMS allows us to define the data, as well as manipulate it. Apply security and integrity measures and recover / restore them after a possible failure.
There are number of advantages when it comes to building and defining the database for different applications. As it make easy processes and also their maintenance. Among other functions, it helps to carry out such important actions as the definition of the data, the maintenance of its integrity, its manipulation and the control of its security and privacy.
By assuming a separate point with respect to the file management system, it’s development is due to the fundamental objective of correcting the difficult of the latter. By providing efficiency and security when extracting or storing information in the databases.
Among its main functions are seven:
- Contribute to the creation of more effective and consistent databases.
- Determine the storage structures of the system.
- Facilitate data searches for business users.
- Help preserve the integrity of the informational assets of the company.
- Introduce changes in the data, when it is required.
- Simplify the consultation processes.
- Control the movements observed in the database.
A data manager, In short, provides a series of services and languages for the Creation, Configuration and Manipulation of the Database. As well as backup mechanisms. It also allows you to store a description of these languages in a data dictionary. As well as their maintenance, providing controlled access to it.
Some important advantages of DBMS are:
- DBMS satisfies current and future application needs of an organization
- It allows only authorized persons to have access to the data stored in database.
- DBMS makes data modification simple with change in hardware additionally.
- It provides data security and integrity
