knoda is one of those cool looking and functionally promising projects. If you are still looking for graphical interface for database management, then try it out.
Its driver concept allows a uniform connection to different database servers (Dbase/Xbase, MS Access/Mdbtools, Mysql , Postgresql , SQLite or ODBC).
Did you notice that MS Access was mentioned? Well, here is a little more for you to know:
New test version knoda 0.7.4-test1 released. With its latest release knoda introduces a driver for MS Access databases (mdb files). Knoda is the first KDE based database frontend reading MS Access databases natively and so it is getting closer to its goal to be a full replacement for MS Access. The driver is based on Mdbtools.
