Ajaxed MySQL Admin: SQL Buddy
SQL Buddy is an open source web-based MySQL administrator with an Ajaxed interface.
It requires no setup and works once the files are uploaded.
SQL Buddy handles logins with the MySQL user tables. Ordering & resizing the columns makes browsing easier.
Although browsing is mostly with Ajax, the application is browser back-forward friendly. And, it enables you to import/export to/from .CSV files.
