The Relational System - Mastering phpMyAdmin 2.8 for Effective MySQL Management - page 159

It is now time to adjust all the relational-features related parameters in config.inc.
php . Here we use the default values mentioned in the comments inside the file; these
database and table names are the ones that have just been created:

$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
$cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';
$cfg['Servers'][$i]['relation'] = 'pma_relation';
$cfg['Servers'][$i]['table_info'] = 'pma_table_info';
$cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';
$cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';
$cfg['Servers'][$i]['column_info'] = 'pma_column_info';
$cfg['Servers'][$i]['history'] = 'pma_history';

As table names are case sensitive, we must use the same
names as the tables created by the installation script. We
are free to change the table names (see the right-hand part
of the configuration directives listed) provided we change
them accordingly in the database.

Each table has a specific function:

pmadb : Defines in which database all the tables are located.
bookmarktable : Contains the bookmarks (explained in Chapter 14).
relation : Defines inter-table relations, as used in many of phpMyAdmin's
features.
table_info : Contains the display field (explained later in this chapter).
