What database front end do you use? What database front end do you use?
It should let you manage databases, tables, indexes and ideally even data records.
And it should ideally be free so we can all use it too.

Databases that it could work with:


MySQL
MS SQL
Oracle
SQLite


One answer per frontend, to let voting do its trick.
I use HeidiSQL, its free and open source. 

Only for MySQL, and only on Windows.

Its fast, and supports multiple servers, multiple databases, and lets you edit:


Users
Tables, columns, indexes
Views, procedures, triggers, events
Data


It also has good data management features:


Filtering, searching
Export to SQL
Export/import XLS


And it looks nice!
