Glom library (a database designer and user interface) - library

 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.
 The design is loosely based on FileMaker Pro, with the added advantage of
 separation between interface and data. Its simple framework should be enough
 to implement most database applications. Without Glom these systems normally
 consist of lots of repetitive, unmaintainable code.
 .
 This is the library package.
