With Glom you can design table definitions and the relationships between them, plus arrange the fields on the screen. You can edit and search the data in those tables, and specify field values in terms of other fields. It's as easy as it should be.

Glom 1.1/1.2 adds some new features and minor UI changes and includes bugfixes from the Glom 1.0.x branch.
