What is a Database?

A database is simply stored information, organized in a useful manner. For example, a list of names and phone numbers could make up a database. The names are stored in a manner that associates each name with its respective number so that you can easily look up one by knowing the other.

The contents of a database system are structured into tables with rows and columns that allow for the easy retrieval of information. In the commonly used relational database application, data from multiple tables is associated with a common key such as an account number or name so that various pieces of data can be stored in different tables with minimal duplication.

The computer application used to create the database tables and structure, and to store and retrieve the data is called a database management system (DBMS) and common examples include MySQL and Microsoft SQL Server. Structured Query Language (SQL) is a programming language used to query a relational database to, among other functions, input, extract and update records in a DBMS.
