Spreadsheet with Python scripting and database interface?

[Wolfgang Keller]

Hello,

I'm looking for a spreadsheet application (MacOS X prefered, but
Windows, Linux ar available as well) with support for Python scripting
(third-party "plug-ins" are ok) and a database interface.

Applications that I know of (that they exist) are:

MS Excel
Quattro
Lotus
OO Calc
Gnumeric
Kspread

Which ones have I forgotten?

Which ones have support for Python scripting?

Excel: I know of a module that allows to script Excel in Python from
outside (COM scripting on Windows and Applescript on MacOS are know as
well), but I don't know of any possibility to do Python scripting with
Excel itself?

OO Calc: I know that PyUNO exists, but I know nothing about what it can
actually do?

Kspread: Koffice seems to have Python scripting support, but I have no
clue what you can actually do with it?

The database interface should ideally allow to:

- map database tables, views, query results to tables/lists (with as
little programming as possible)
- allow editing of records within those tables/lists (and write back
the results)
- supply possibilities to handle relationships (via foreign keys)
between records in different tables in a user-friendly way (I have
something like hyperlinks in mind)

The database software to interface with is Postgres.

The application "should" also provide good support for naming of
cells/columns/rows/regions (including namespaces for files, sheets) and
user-defined formats.

TIA,

Sincerely,

Wolfgang Keller
