Defining the display column
On the workspace, the name column in author table has a special background color.
This indicates that this column serves as the display column. We can simply click
on the Choose column to display icon, and drag the short message Choose column
to display onto another column—for example, the phone column. This changes the
display column to this column. If we were to drag the message to an existing display
column, we would have removed the definition of this column as the display column
for the table.
Exporting for PDF schema
In Chapter 15, we will see how to produce a PDF schema for a subset of our
database. We can import the coordinates of tables from such a schema into the
Designer 's workspace, and conversely export them to the PDF schema. The Import/
export coordinates icon is available for that purpose.
Benefiting from the defined relations
In this section, we will look at the benefits of the defined relations that we can
currently test. Other benefits will be described in Chapter 12 and Chapter 15 .
Additional benefits of the phpMyAdmin configuration storage will appear in
Chapter 14 , Chapter 16 , and Chapter 18 .
These benefits are available for both internal and foreign key relations.
Foreign key information
Let us browse the book table. We see that the values of the related key ( author_id )
are now links. Moving the cursor over any author_id value reveals the author's name
(as defined by the display column of the author table).
