kexi
KEXI is considered as a long awaited Open Source competitor for MS Access, Filemaker and Oracle Forms. Its development is motivated by the lack of Rapid Application Development (RAD) tools for database systems that are sufficiently powerful, inexpensive, open standards driven and portable across many operating systems and hardware platforms.

Kexi development has come along nicely. Much more functionality in recent versions. I'm using 3.1. Definitely worth trying now. Really appreciate the ease of developing forms for custom data entry. Seems to have very active development.
good ideas. be cautios with the sql button when opening queries (at least if the database type is "file"). there are two features missing to create a productive database user interface: listboxes (or a datagrid) and subforms
Greatly improved in recent incantations. More stable, more features. You really need to build a later version than offered here. I use it all day, every day, from a postgresql server. Good development team actively working on it fixing bugs, adding new features, etc.
Faster than Base, but OMG so difficult to use. Lacks a lot of common-sense features. Claims to be an MS Access alternative but fails miserably. Do yourself a favor - install MySQL instead.
