DATABASES

Nowadays, computers are used everywhere and some uses are like in offices,schools,hospitals,etc.

We often need to store huge amount of records in the places listed above.

For this we require various softwares which are called DBMS(Database Management System).A DBMS is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.
Some DBMS examples include MySQL, PostgreSQL, Microsoft Access, SQL Server, FileMaker, Oracle, RDBMS, dBASE, Clipper, and FoxPro.

There are four structural types of database management systems:

• Hierarchical databases.
• Network databases.
• Relational databases.
• Object-oriented databases.
