GENERAL: PosgreSQL Inquiry

От

    We are doing a conversion from HP3000 to an Intel based system
    running Unix & will need an RDMBS.  The DB will function as a data
    server for our core of COBOL programs.  I am not a database guy
    but am trying to research this issue & determine whether PostgreSQL
    will satisfy our needs & get at least some idea of how it might work.
    It seems that the best way for COBOL to communicate with the DB
    would be embedded code but it does not appear that PSQL supports this.
    Though this will not be a browser based system, ODBC probably would
    work.  Would this be as fast as embedded code using Oracle, DB2 or???

    Thanks for any insight you may be able to provide.

Can you compile C programs into your COBOL programs? It would be plenty fast.

I refer you to this article from a month or so ago:

http://archives.postgresql.org/pgsql-general/2003-04/msg00059.php

According to him, his flavor of Cobol is converting from embedded SQL to
ODBC automagically.
