Database Systems

Database systems store and support efficient processing of data. A database system may contain multiple databases. Within a database, data is often stored in tables. Users and administrators can interact with a database system using Structured Query Language (SQL). SQL provides commands to create tables, insert data into tables, delete or update information, query the database and display information from tables. Examples of database systems are: MySQL, SQL Server, DB2 and Oracle.
