What do you think of Postgres and Firebird Databases?
Firebird-Fyracle supports the major
Oracle-based ERP/CRM application
“Compiere” — with virtually no change
to the Compiere code base. Fyracle has
supported Compiere since version
2.4.2b, which contained over 20,000 lines of PL/SQL. The current release,
2.5.3c, has moved most PL/SQL into stored procedures written in Java,
which is also supported by
Firebird-Fyracle.
