Summer of NHibernate Session 14: Migrating to NHibernate 2.0 and Further Exploration

Sun, 05 Oct 2008 11:54:14 GMT

In this final installment of the series we migrate our data-access-layer and related unit tests to support NHibernate 2.0 and in the process uncover some understanding of breaking changes. We also take a quick 10,000-foot view of several other OSS frameworks and libraries that can enrich and complement your use of NHibernate in your applications.

Summer of NHibernate Session 13 (corrected) screencast is now available

Somehow Camtasia silently truncated the final 5 minutes or so of the initial post of this installement so here it is again (corrected). Sorry for any trouble this may have caused anyone~!

Summer of NHibernate Session 13: Managing Session Lifecycle in a Stateless Web Application

Mon, 29 Sep 2008 00:43:54 GMT

In this installment we dig into the patterns for managing ISession lifecycle in ASP.NET web applications and spend some time understanding the pros of and cons of the various strategies that can be employed to work with an ISession instance across multiple page request/response actions.

Summer of NHibernate Session 12: Detached Objects, Detached Criteria, and Working Without A Session

Thu, 04 Sep 2008 11:15:20 GMT

In this installment we investigate ISession lifecycle, understand how to detach and reattach objects to and from an ISession instance, and explore the flexibility that Detached Criteria gives us to refactor our data-access-code into much more resuable elements.

Summer of NHibernate Session 11: Modeling Inheritance in the Database

Sat, 30 Aug 2008 03:36:47 GMT

In this session, we explore NHibernate's various techniques for modeling OO inheritance in the database, explore the meaning and power of polymorphic queries (try THAT with the Entity Framework~!), and understand how inheritance modeling choices affect the SQL that is sent to the database.

Summer of NHibernate Session 10

Thu, 21 Aug 2008 16:01:53 GMT

In this session we explore some miscellaneous topics including digging into NHibernate's support for working with stored procedures, our ability to react to events on the Session object through the use of Interceptors, and also take a quick look at the NHibernate Query Analyzer tool.

Summer of NHibernate Session 09

Mon, 18 Aug 2008 15:48:25 GMT

In this installment we explore the capabilities of the NHibernate SchemaExport class and discover how it can be used to completely slave our database schema to our object model in order to better support some of the tenets of Domain Driven Design.

Summer of NHibernate Session 08

Sun, 10 Aug 2008 14:13:02 GMT

In this latest installment of the series, we dig into techniques for using code-generation tools to completely slave the design of our Data Transfer Objects and their related .hbm.xml mapping files to the content of our database schema to support a database-first style of approach to designing your application.

Session 07: Exploring m:n Relationships, Views, and Components

Mon, 04 Aug 2008 10:43:50 GMT

In this session we explore NHibernate's support for many-to-many relationships, investigate techniques for interacting with VIEWS in our database, and enrich our bare-bones object model by introducing a 'Name' Component to our 'Customer' class.

Session 06: Advanced Querying of Child Collections

Sun, 27 Jul 2008 23:44:22 GMT

In this session we further refactor our NHibernateDataProvider class to improve its session management, investigate querying child collections using both HQL and the Criteria API, and dig into the messy details of returning distinct object from queries.

Session 05: Modeling Foreign-Key Relationships in NHibernate

Sat, 19 Jul 2008 13:20:50 GMT

In this session we introduce the concepts behind NHibernate's support for modeling FK relations using collections of objects, extend our mapping files to reflect relationships between our objects, dig into the concepts of Lazy Loading, and explore NHibernate's options for collection mappings.

Session 04: Introducing Transactions and Concurrency

Sat, 12 Jul 2008 16:44:09 GMT

In this session we dig into managing Commit() and Rollback() of transactions using NHibernate, explore handling row-versioning and concurrency, refactor our data-access-class to squash a bug, and introduce liberal use of the using(...) statement to help keep our Garbage properly Collected

Session 03: Exploring INSERT, UPDATE, and DELETE Semantics

Mon, 07 Jul 2008 23:52:37 GMT

In this session we do some housekeeping to support our data-dependent unit test needs and then dive into asking NHibernate to perform UPDATEs, INSERTs, and DELETEs on our database.

Session 01: Setup and Basic Usage Pattern

Wed, 18 Jun 2008 1:31:00 GMT

In this session we setup the VS IDE to leverage the NHibernate mapping and config schema files, wite our first Nhibernate-enabled class and its accompanying XML mapping file, and get our first data out of the database.

Session 02a: Exploring Query Methods and Syntaxes (con't)

Thu, 26 Jun 2008 3:11 GMT

In this session we look at GROUP BY and ORDER BY predicates in queries as well as returning custom objects from the database.

Session 02: Exploring Query Methods and Syntaxes

Thu, 19 Jun 2008 8:16 GMT

In this session we explore basic quering syntax in NHibernate using HQL and the Criteria API to begin to interact with our database.
