NHibernate and Castle ActiveRecord Tutorial for the Uninitiated

http://davidhayden.com/blog/dave/archive/2008/04/28/NHibernateCastleActiveRecordTutorialUninitiated.aspx

Speaking of O/R Mappers, if you are into the ActiveRecord Design Pattern and want to use an O/R Mapper that uses the ActiveRecord Pattern, don’t forget about Castle ActiveRecord:

”The Castle ActiveRecord project is an implementation of the ActiveRecord pattern for .NET. The ActiveRecord pattern consists on instance properties representing a record in the database, instance methods acting on that specific record and static methods acting on all records. Castle ActiveRecord is built on top of NHibernate, but its attribute-based mapping free the developer of writing XML for database-to-object mapping, which is needed when using NHibernate directly.”

I have talked about ActiveRecord and Castle ActiveRecord quite a bit in the past:

• Castle ActiveRecord – Active Record Pattern Built on NHibernate – ASP.NET C#
• ActiveRecord Pattern and Layer Supertype – Domain Model and Domain-Driven Design
• Active Record Design Pattern – Domain Driven Design and Domain Layer – Object Persistence
• Domain-Driven Design Using Active Record in .NET
• ActiveRecord – Playing More with Hayden.ActiveRecord Framework for .NET
• WCSF and Castle ActiveRecord

If you are interested in Castle ActiveRecord, The NHibernate FAQ has a new tutorial here on getting started with Castle ActiveRecord.

Fluent NHibernate Auto-Mapping Tutorials – O/R Mappers

http://www.pnpguidance.net/post/FluentNHibernateAutoMappingTutorialsORMappers.aspx

I suspect that NHibernate will be gaining in momentum in the .NET Developer Community given that LINQ To SQL is dead and the Entity Framework received a vote of no confidence by the developer community at large. I think this is actually a good thing as most .NET Developers need to increase their exposure to non-Microsoft products.

Fluent-NHibernate – Losing Those Ugly XML Configuration Files

I believe Fluent NHibernate will actually help NHibernate gain momemtum given that it makes NHibernate more palatable for the average .NET Developer. It gets us out of XML Hell and allows us to use conventions over configurations to make it easier to map entities to database tables in NHibernate. I briefly talked about Fluent NHibernate in a few posts:

• Sample Fluent NHibernate T4 Templates for Code Generation via LINQ To SQL
• AutoPersistenceModel in Fluent NHibernate – NHibernate O/R Mapper
• Fluent NHibernate Project – NHibernate Entity Mapping Minus XML

 

James Gregory, who is on the Fluent NHibernate team, has written a number of good tutorials recently on Fluent NHibernate to help you get up to speed on using it to help map business entities to tables in your NHibernate Applications. Here is a link to James’ category on Fluent NHibernate. Check out his tutorials.
