# Viewing table references and extensions

View table relationships in a visual manner using the schema map.

The schema map displays the details of tables and their relationships visually, allowing administrators to view and easily access different parts of the database schema.

The schema map can also be printed directly from a browser.

|Relationship type|Color used|
|-----------------|----------|
|Referenced by|Red|
|Referencing|Orange|
|Extended by|Green|
|Extending|Blue|

By default, each type of relationship is displayed. However, you can view or hide each type as needed.
