You can select any individual table to automatically highlight its relationships to other tables, and you can expand the keys section of the table to see detailed information. When you select any table, its connecting lines are color-coded:

• Blue connecting lines signify references to other tables
• Orange connecting lines signify references from other tables
• Green connecting lines identify table self-references

You can insert sticky notes anywhere in your entity relationship diagram to record special comments to explain design decisions or modifications, or otherwise enhance the documentation value of your table relationship diagram.

You can also select any connecting line in your ER diagram to automatically identify and highlight the related tables.
