List All MySQL Structures
"List All MySQL Structures" software was created with developers in mind (including this programmer). The tool may come in handy even if you are not a developer.
With the click of one button, the software will display the structure of each table of each database accessible by a username/password combination. No more twiddling with phpMyAdmin to try to figure out how a table is constructed.
