A database is a collection of data organized in tables that can be queried and manipulated. A database management system (DBMS) allows users to add, insert, retrieve, change, and delete data from the database. The relational model represents data in tables with rows and columns and allows queries using SQL. The Perl DBI provides a standardized interface to connect to and interact with different database systems from Perl code.
