Do you intend to use standard SQL and nothing else? Very few do that. If you do they are both claiming to support the same standard level. Otherwise Informix is with their new Universal Server very far in front. So far that there is realy little comparison. :- Replication and syncronization capabilities to remote sites See other discussion in this thread. The conclusion seems to me to be that Informix has a much simpler and cleaner design that should lead to much less maintenance problems and the same or better performance. :- Level of difficulty in maintainig and supporting the Oracle server vs. :Informix server Traditionally Informix have been significantly simpler on this account. It probably still is. :- Learning curve associated with the above products for DBA and sql :users See above. :- the kind of support to expect from their support staff or do we have :to depend : on the net to answer most of our questions The support from Informix is simple outstanding. Some may tell you otherwise, but this is our experience, and I think it can be duplicated by anyone if you understand how their support organisation works. If you have any problems your support call can easily be escalated, and you are the one to do that - not Informix (although they can of course also). :- How often do we run into bugs in their software Probably not very different. :Please excuse my ignorance and if possible please spare the flames. :Also please send all responses directly to my e-mail: iac@frc.com :Thanks a lot. All positive feedback is appreciated and if requested will :summarize :and post it to the requested newsgroups. For a technical comparison with some errors in Informix's disfavor (particularly when considdering their latest releases - OnLine DSA 7.21 and Universal Server) you might want to look at: http://www.dbms.mfi.com/9611d52.html One point from this comparison: It says Oracle have only forward type cursors while Informix have (and has allways had) true scrolling cursors. If this is true I would have had significant problems if I used Oracle. Of course you can allways implement scrolling "cursors" at the application level, but it isn't quite the same thing. If the comparison had included the Informix Universal Server it would have looked quite different.
