Since this book is about SQL Server 2005 Integration Services, you will get more out of it if you have the developer edition of SQL Server 2005 installed, including the sample applications and the tools. This book has been written for SQL Server 2005 with SP2 installed (which was released in February 2007). If you do not have a licensed copy of SQL Server 2005, you can download a 120-day trial from the Microsoft download site at http://download.microsoft.com.
