The '''.NET Persistence API''', also referred to as '''NPA''', is a persistence and [[Object-Relational_Mapping|Object Relational Mapping (ORM)]] specification for the [[.NET_Framework|.NET framework]]. <ref>http://www.npersistence.org/</ref>

NPA is based on the [[Java_Persistence_API|Java Persistence API (JPA)]], which is the standard persistence API in the [[Java (programming language)|Java]] world. NPA follows JPA by providing a complete persistence API and a rich set of ORM features.<ref>http://www.npersistence.org/faq</ref>

==Motivation==

The main purposes of the .NET Persistence API (NPA) are:<ref>http://www.npersistence.org/faq</ref>

* To provide a vendor free persistence API for .NET, making switching from one persistence provider to another easier (avoiding [[Vendor_lock-in|vendor lock-in]]).

* To provide a cross language persistence API by extending the popular [[Java_Persistence_API|Java Persistence API (JPA)]] to all the .NET programming languages.
