Help me choose a database

Hello.

  I am cross-posting this message across all the comp.databases.* newsgroups   iin an attempt to get as much info as possible from people who specialize   or are very familiar with one or more database packages.

  I am in the proccess of designing a real-time system under MS-DOS. I need   a database that will either have a library that can interface with C or   a more 'application generator' type database that will allow interupst to   be recived and handled.

  From the adds I have read, packages like CodeBase 5.0 seem much more   practical then something like FoxPro - simply due to it's flexibilty   and, since it is a library - it won't hog all my resources.

  I hesitate to use the phrase client/server as that isn't quite the case here,   but there is communication between many databases on many machines, with   a main file server.

  I need something that is going to be REALLY fault tolerant, that will be   able to recover from a crash with minimal data loss and no corruption.   It needs to be able to deal with over a 3 million records, and must be   as fast as possible ( obviously :-) ).

  While I am sure y'all must get posts like this a zillion times a month,   I would really appreciate if you could all share some of your experience   with me. In return, I will post back a tabularized version of all the info   I get, so maybe this won't happen too often.

  If you could please reply by e-mail, as I don't read the news often.

                                        Thanks,
                                           Michael
