Before the creation of software to handle storage man has been able to keep records of events, statistics and data in an orderly and systematic approach for easy analysis and reference through use of tools such as books , albums. These records can be said to be database because they hold data specific to a particular scope.

before we can define a database we need to explain what makes up a database to understand what  they are.

For you to be able to manipulated data stored in a computer database you need a database management system

What is a database management system or DBMS?

Database management systems are computer Software applications that interact with the user, other applications, and the database itself to capture and analyze data.

Basically there are just software that hide all the complex functions being performed at the backend and provide the user with an easy understandable front end or interface and they handle all user request from the front and send it to the database and also retrieving this information from the database and prints it out in a user friendly manner. Simply put, it acts as in intermediary between the user and the database

A general-purpose DBMS is designed in such away it allows manipulation of databases. these manipulations include definition, creation, querying, update, and administration of database. examples of well-known Database management softwares include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, Sybase and IBM DB2.

Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language. Sometimes a DBMS is loosely referred to as a ‘database’.
