A '''Data access layer''' is a [[modulelayer (object-oriented design)|layer]] of a [[computer programming]] [[logicprogram]] which provides simplified [[access]] to [[data]] stored in [[persistent storage]] of some kind, such as an [[entity-relational database]].

This Data Access Layer is used in turn by other program modules to access and manipulate the data within the data store without having to deal with the complexities inherent in this access.
