The Ajax-based Designer feature appeared in phpMyAdmin 2.10. It offers a mouse-driven way of managing relations—both internal and InnoDB-based—and of defining the display field for each table. It can also act as:
A menu to access the structure of existing tables and to access the table creation page.
A PDF schema manager, if we want a PDF schema encompassing all our tables.
On the Designer workspace, we can work on the relations for all tables on the same panel, whereas the Relation view shows the relations for a single table at a time.
We access this feature from the Database view by clicking the Designer menu tab.
