You'll need to keep in mind that layouts and tables are two different things. You can have any number of different layouts that all display information from the same table.
Open Manage | Database | Tables
How many tables are listed there?
Click the relation ships tab. How many "boxes" (Called table occurrences) are there?
Are they linked? How?
There are 5 tables (products, pictures, drawings, standard, and options). There are 5 table occurrences. This is how they are linked:
product::model# = options::model#
product::model# = standard::model#
product::model# = drawings::model#
product::model# = pictures::model#
What should I do next?
You have various options. You can use a portal to display related records from one table on another layout.
For example, you could place a portal to Pictures on your Product layout and all related pictures for a given product record can be displayed in the portal.
You can also write scripts so that when you move from one layout to another, the records with matching records are "found" and displayed on the other layout. You can attach those scripts to a button.
A simple script to show all drawings for the current record on the product layout:
Set Variable [$Model; Product::model#]
Go To Layout ["Drawings" (Drawings)]
Enter Find Mode
Set Field [drawings::model#; $Model]
Set Error Capture [on]
If [ get ( foundcount ) = 0 /* no drawing records were found */]
Show Custom Dialog ["No drawings were found"]
