Developers can make notes or comments on a database diagram, by adding text annotations. When developers working with SQL Server “Denali”, MS SQL Server 2008 R2 and MS SQL Server 2005 want to add text annotations to diagrams, they should follow the next steps:
1. Open the diagram to which they want to add an annotation.
2. Right-click in the empty space of the Diagram window.
3. From the shortcut menu click New Text Annotation.
4. Type their note into the text field that appears.
