Or two of code.NHibernate uses mapping files to guide its translation from the database to business objects and back again. As an alternative, you can use attributes on classes and properties, instead of mapping files. To keep things as simple as possible, we're going to use mapping files in this article, rather than attributes. In addition, mapping files make for a cleaner separation between business logic and persistence code.So, one need only add a few lines of code to an application and create a simple mapping file for each persistent class, and NHibernate takes care of all database operations. It is amazing how much development time is saved by using NHibernate.Note that NHibernate is not the only ORM framework in the .NET universe. There are literally dozens of commercial and open source products that provide the same services. NHibernate is among the most popular, probably because of its heritage as a descendant of Hibernate, a popular ORM Framework in the Java universe. In addition, Microsoft has promised an 'Entity Framework' for ADO.NET, to provide ORM services. However, the product has been delayed, and it may not be released for some time.Installing NHibernateThe first step in using NHibernate is to download NHibernate and Log4Net, an open-source logging application that NHibernate can use to record errors and warnings. NHibernate contains the most recent Log4Net binary, or you can download the entire Log4Net install package. Here are the download locations:NHibernateLog4Net Log4Net is not strictly required to use NHibernate, but its automatic logging can be very useful when debugging. Getting StartedIn this article, I am going to use a very simple demo application (the demo app) that does no real work, other than demonstrating data access with NHibernate. It is a console application, which simplifies things by eliminating UI code. The application creates some

Download demo project - 1,162.6 KB IntroductionThis article grew out of my frustration trying to get started with NHibernate. It seemed that all the introductory material I found was either very vague or so detailed that I got overwhelmed before getting to first base. What I was looking for was a simple, straightforward tutorial that would get me up to speed on the fundamentals of NHibernate as quickly as possible. I never found it. Hopefully, this article will serve those needs for other people.This article is going to be rather lengthy, but I encourage you to work your way through it. NHibernate is a complex piece of software, with a steep learning curve. This article will flatten the curve from a matter of days or weeks to a matter of a few hours.The ProblemNHibernate addresses the well-known problem that object persistence code is a pain in the neck to develop. Various articles estimate that from one-quarter to one-third of application code in an n-tier application is dedicated to the "persistence tier"—reading business object data from a database and writing it back again. The code is repetitive, time-consuming, and a chore to write.Various solutions to this problem are available. Code generators can create data access code in seconds. But if the business model changes, the code has to be re-generated. "Object-relational managers" (ORMs) like NHibernate take a different approach. They manage data access transparently, exposing a relatively simple API that can load or save an entire object graph with a line or two of code.Introducing NHibernate Hibernate is a persistence engine in the form of a Framework. It loads business objects from a database and saves changes from those objects back to the database. As we mentioned above, it can load or save an entire object graph with just a line

Is initialized, and use that SessionFactory to create session objects as needed. The demo project initializes a PersistenceManager object as part of the application initialization. The PersistenceManager configures a SessionFactory, which becomes a member variable of the PersistenceManager. The application can call PersistenceManager.SessionFactory to create sessions as needed.Configuring NHibernate – Configuration DataThere are two elements to configuring NHibernate:Configuration dataConfiguration codeConfiguration data can be placed either in a separate configuration file in the application root directory, or in the App.config file for the application. To keep things simple, the demo app places the data in the App.config file. It means one less file to get lost or separated from the rest of the application.At the beginning of this article, we suggested downloading Log4Net along with NHibernate. Log4Net has its own configuration data, which we will place in the App.config folder as well. The Log4Net configuration data is straightforward, so we will not cover it here. Note that both NHibernate and Log4Net need tags in App.config's section.NHibernate's configuration data is reasonably clear. The data is used by NHibernate to create a SessionFactory. Here are the SessionFactory properties that are set from the data:Connection provider: The IConnectionProvider that NHibernate should use. The demo app uses the default provider.Dialect: Which database dialect to use. The demo app specifies the SQL Server 2005 dialect.Connection driver: Which ADO.NET driver to use. The demo app specifies the SQL Server client driver.Connection string: The connection string to use in connecting with the database. The connection string is a standard ADO.NET connection string; you do not need to modify a valid connection string to use it with NHibernate.Note that the connection string in the demo app is valid for the author's development environment. You will need to change the connection string to match your database setup.Configuring NHibernate – Configuring.

Download Smart Code Setup, include source code (External Site) Overview As described in the part one of this series, SmartCode uses a template engine to transform some kind of "model" into compilable code. In this second part of the series, I will teach how to build a template to generate stored procedures, and finally how to use the new Open Source Implementation of a CodeSmith-Style Code Generation Engine (TahoGen). Also you can jump to the third part of the serie, to play with NHibernate and Smart Code. Now Smart Code offer a new set of Templates to generate code for NHibernate + ASPX, the code is based on the NHibernate Best Practices with ASP.NET article. More info about these templates in the article named NHibernate Templates for Smart Code Generator. Introduction Most of the real-world code generators, both commercial and open source releases, use script based templates and template engines to transform data from a format to another. In the .NET Framework, usually code generators templates are written in ASP.NET style syntax. And using .NET class, associated to an specific data model to transform this input, in an formatted output, specified by the template SmartCode is a very flexible, powerful and open source code generator. The most new features of SmartCode is an alternative to tipical ASP.NET code styles. The Templates are created in C# or VB.NET (or theoretically in any .NET language in which a dynamic-link library (DLL) may be created) and compiled as dlls. This is a very powerful paradigm, to allow you using Visual Studio to create, compile and debug the templates. Template Libraries Code-generation templates are organized in dlls. For a DLL to be considered an SmartCode library, it has to expose a certain interface, which will be specified in detail in the next section. To

Business objects, uses NHibernate to persist them, and then reads them back from the database. You will need to do several things to run the demo app on your machine:Replace references to NHibernate and Log4NetAttach the NhibernateSimpleDemo databaseModify the connection stringThe demo app contains references to NHibernate and Log4Net. The references should be valid on your PC, so long as NHibernate and Log4Net are installed in their default locations. If the references aren't valid, you will need to replace them with references to NHibernate (NHibernate.dll) and Log4Net (log4net.dll) as they are installed on your PC. The DLLs can be found in the NHibernate installation folder on your development PC. The demo app is configured to use SQL Server Express 2005. The database files (NhibernateSimpleDemo.mdf and NhibernateSimpleDemo.ldf) are packaged with the demo app. You will need to attach the database to SQL Server on your machine.Finally, the connection string in the App.config file assumes that you are running a named instance of SQL Server Express 2005, and that the instance is named 'SQLEXPRESS'. If your PC is running a different configuration of SQL Server 2005, you will need to modify the connection string in the App.config file. Note that the database will not work with older versions of SQL Server.The Business ModelThere are two ways to develop an application with NHibernate. The first is a "data-centric" approach, which starts with a data model and creates business objects from the database. The second is an "object-centric" approach, which starts with a business model and creates a database to persist the model. The demo app uses the object-centric approach.Here is the business model for the demo app:The model represents the skeleton of an order system. The model is not complete—there are just enough classes to demonstrate object persistence with NHibernate. And there is

Date that NHibernate uses is contained in separate XML files. This approach loosens the coupling between business classes and data-access classes, resulting in a more flexible, easier-to-maintain business tier. The only requirement that NHibernate imposes is that collections be typed to interfaces, rather than concrete types. That's a practice that is generally recommended for all OO programming, and it does not bind business classes to NHibernate in any way.The DatabaseHere is the database that the demo app uses to persist the model:Note that the database and the object model do not match perfectly. The object model has an Address class that has no corresponding table in the database, and the database has an OrderItems table that has no corresponding class. This mismatch is intentional. One of the aspects of NHibernate that we want to show is that there need not be a one-to-one correspondence between classes and database tables.Here are the reasons for the mismatch:The Address class does not represent an entity in the business model. Instead, it represents a value held in an entity, in this case, the Customer.Address property. We encapsulated the address in a separate class so that we can demonstrate what NHibernate calls "component mapping".The OrderItems table is a link table in a many-to-many relationship between Orders and Products. As such, it does not represent an entity from the business model.The Customers table contains a skeleton of the usual customer information, including the customer's address. Best practice would call for the address in a separate table, contrary to what we have done here. We included address information in the Customers table so we could demonstrate how to persist what NHibernate calls 'components'—classes that do not have their own tables. We will discuss components in more detail below.The Orders table has a bare minimum of information; only.
