NHibernate 2 Beginner's Guide

By: Aaron Cure

Overview of this book

<p>NHibernate is an open source object-relational mapper, or simply put, a way to retrieve data from your database into standard .NET objects. Quite often we spend hours designing the database, only to go back and re-design a mechanism to access that data and then optimize that mechanism. This book will save you time on your project, providing all the information along with concrete examples about the use and optimization of NHibernate.<br /><br />This book is an approachable, detailed introduction to the NHibernate object-relational mapper and how to integrate it with your .NET projects. If you're tired of writing stored procedures or maintaining inline SQL, this is the book for you.<br /><br />Connecting to a database to retrieve data is a major part of nearly every project, from websites to desktop applications to distributed applications. Using the techniques presented in this book, you can access data in your own database with little or no code.<br /><br />This book covers the use of NHibernate from a first glance at retrieving data and developing access layers to more advanced topics such as optimization and Security and Membership providers. It will show you how to connect to multiple databases and speed up your web applications using strong caching tools. We also discuss the use of third-party tools for code generation and other tricks to make your development smoother, quicker, and more effective.</p>

Can I get help using NHibernate?


There is a great community site for NHibernate on the Web called the NHibernate Forge. It is located at http://www.nhforge.org/, and it provides a wealth of resources for the new and veteran NHibernate user.

Have a go hero – looking at some sample files

A basic NHibernate project is composed of three major parts. You will need a mapping file to tell NHibernate how the database is or should be (see the Mapping our types section in Chapter 4) constructed, some data access methods to tell NHibernate what data you want to retrieve or store into the database, and a POCO to allow you to interact with the data. While XML mapping files are commonly used in NHibernate projects, they are not the only way to map data to POCOs (more in Chapter 4).

Take a look at some sample files, but don't get too hung up on them. We'll go into more detail in the later chapters.
