NHibernate is a port of Hibernate Core for Java to the .NET Framework. It handles persisting plain .NET objects to and from an underlying relational database. Given an XML description of your entities and relationships, NHibernate automatically generates SQL for loading and storing the objects. Optionally, you can describe your mapping metadata with attributes in your source code.NHibernate uses the following ways to retrieve objects from the database:- Hibernate Query Language (HQL)
- Query By Criteria (QBC) and Query BY Example (QBE) using Criteria API
- Native SQL queries
