I have a huge ETL script that I am planning to understand. Are there any visual tools that can help me understand it more easily? I am using SQL Server 2005.

            This tool, SQL Enlight, may help you:
For example, see the section "Summarize T-SQL script" of this URL.
Unfortunately, its not a free product, but they do offer a free trial.
