NHibernate provides a robust Object-Relational Mapping solution for .NET applications, simplifying database interactions with efficiency and ease of use.

NHibernate is an open-source object-relational mapping (ORM) solution for the .NET framework. Created by the JBoss community, a division of Red Hat, NHibernate aims to simplify data access layer coding by reducing the amount of repetitive boilerplate code needed.

With NHibernate, developers can map their domain-specific classes to database tables and perform CRUD (Create, Read, Update, Delete) operations without directly writing SQL queries. The library supports a variety of database systems, including Microsoft SQL Server, Oracle, and MySQL.

NHibernate also provides support for caching and lazy loading, which can help improve application performance. Additionally, developers can customize how NHibernate translates their domain-specific objects to database queries by creating custom mapping classes or by using attributes to configure the mapping.

How does NHibernate handle transactions?

NHibernate provides support for managing transactions using either explicit transaction demarcation (using BeginTransaction/Commit/Rollback methods) or implicitly through various configuration options.

Can NHibernate be used in ASP.NET applications?

Yes, NHibernate can be used in ASP.NET applications. It can provide persistence and data access layer functionality for web applications built using ASP.NET MVC, Web Forms, or other frameworks.
