Databases

A database is a large collection of related (and often structured) data. A database captures an abstract representation of the domain of an application - the (1) records, and (2) relationships between records.

Database management systems (DBMS) are systems for creating, manipulating, accessing a database. The goal of a DBMS is to simplify storing and accessing of data.
