Note that if you're new to NHibernate, the remainder of this article may provide an easier way to learn to understand NHibernate.
Working with object-oriented software and a relational database can be cumbersome
and time consuming in today's enterprise environments. NHibernate is an object/relational
mapping tool for .NET environments. The term object/relational mapping (ORM) refers to
the technique of mapping a data representation from an object model to a relational
data model with a SQL-based schema.
NHibernate not only takes care of the mapping from .NET classes to
database tables (and from .NET data types to SQL data types), but also provides data
query and retrieval facilities and can significantly reduce development time otherwise
spent with manual data handling in SQL and ADO.NET.
NHibernate's goal is to relieve the developer from 95 percent of common data persistence
related programming tasks. NHibernate may not be the best solution for data-centric
applications that only use stored-procedures to implement the business logic in the
database, it is most useful with object-oriented domain models and business logic in
the .NET-based middle-tier. However, NHibernate can certainly help you to remove or
encapsulate vendor-specific SQL code and will help with the common task of result set
translation from a tabular representation to a graph of objects.
