Revision as of 03:48, 15 April 2010
From the FSF High Priority Projects list:
We need a compatible free software replacement for Oracle Forms that works with free SQL databases. This software would allow people currently using the proprietary Oracle DB to more easily migrate to a free software database system, without having to rewrite all of their user-interface applications.

Proposed projects
GNU Enterprise
GNU Enterprise (GNUe) is a meta-project which is part of the overall GNU Project. GNUe's goal is to develop enterprise-class data-aware applications as Free software. GNUe is itself comprised of several subprojects: Developer Tools, ERP Packages and the Community.
Kexi
Kexi is an integrated data management application, designed to fill the gap between spreadsheets and database solutions requiring more sophisticated development. Kexi can be used for designing and implementing databases, data inserting and processing, and performing queries.
The impetus for developing Kexi came from a noticeable lack of applications having the features of Microsoft Access, FoxPro, Oracle Forms or FileMaker while at the same time being powerful, inexpensive, open-standards-driven and sufficiently portable.
Kexi is a part of the KDE project, and runs on GNU/Linux, *BSD, Unix, Mac OS X, Solaris and MS Windows operating systems. It can run with any window manager or desktop (e.g. KDE, GNOME).

Questions
> One question -- does your program actually read forms written in the > Oracle Forms language? That's an important part of what we're looking > for, I think. jstaniek: Such a migration option would be relatively easy (compared to any other tool I have heard about) because Kexi formats are XML-based, operations are client-server or client-middleware-server -oriented, and the GUI framework and abstraction layer is one of the best and based explicitly on Free Software (Qt toolkit, core KDE libraries - no KDE desktop required for operations). That said, Kexi does not share 1-to-1 specs with Oracle Forms, and does not have migration option for these types of forms yet. Regarding Oracle support in Kexi, there is already Oracle driver that enables migrating of data from Oracle to Free Software RDBMS, e.g. PostgreSQL.

I'd even say "80% of the features can take 20% of the time" :) The task is not only with the translation process - we need to add the features that exist in Oracle Forms and not in Kexi (or any other Free Software offerings). As you probably also know from "OpenOffice.org vs MS Office" saga, missing a few percent of features make people stop even considering the switch. But the potential is here, and many Free Software/Open Source supporters do invest in integrated and well extensible tools like Kexi. To be clear, I am unable to push the Oracle Forms migration plugin forward, so we need people dedicated exactly to this task. From my past experience I guess, it would not be too hard to find someone.
