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>

Time for action – creating an ordering system database


So we want to build a simple ordering system. We are going to need to store the orders, the order items, the products they represent, the contact that placed the order, and the billing and shipping addresses. Let's get started!

  1. If you haven't already, install the Microsoft SQL Server Express with Tools, or install Microsoft SQL Server Express and Microsoft SQL Server Management Studio Express (SSMS). If you don't have the .NET Framework 3.5 installed already, then you will need to install that before you will be able to install SSMS, as well as Windows PowerShell. We will use SSMS to design our database.

  2. Open SSMS (Start | All Programs | Microsoft SQL Server (version) | SQL Server Management Studio Express).

  3. When you open SSMS, you will be prompted for login credentials for the database. Generally, you can enter either the hostname\SQLEXPRESS or (local)\SQLEXPRESS.

    Note

    If you changed the name of the SQL Server instance when you installed...
