The .NET Persistence API, also referred to as NPA, is a persistence and object-relational mapping (ORM) specification for the .NET framework.〔(NPersistence | JPA for the .NET platform )〕 NPA is based on the Java Persistence API (JPA), which is the standard persistence API in the Java world. NPA follows JPA by providing a complete persistence API and a rich set of ORM features.〔(FAQ | NPersistence )〕〔(c# - What is the equivalent of JPA in .NET? - Stack Overflow )〕 == Motivation == The main purposes of the .NET Persistence API (NPA) are:〔 * To provide a vendor-free persistence API for .NET, making switching from one persistence provider to another easier (avoiding vendor lock-in). * To provide a cross-language persistence API by extending the popular Java Persistence API (JPA) to all the .NET programming languages. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「.NET Persistence API」の詳細全文を読む スポンサード リンク
