A full comparison of the various databases would be a long report, and is the sort of thing you pay thousands of pounds for. Also, this being a PostgreSQL group, you'd expect more knowledge of that platform and even some bias towards it. You also don't mention what platform/application types/budget you are looking at. > 1. rdbms They all are, for some definition of "RDBMS" - see http://www.dbdebunk.com for why some people think the term is horribly abused. > 2. data independence In what sense? > 3. support of plsql This is an Oracle language. PostgreSQL has something similar plpgsql. > 4. integrity Apart from some of "MySQL's gotchas" (google for the term), they should all be equivalent, assuming you mean what I think you mean. > 5. security Depends what you mean. > 6. use and application Not sure what you mean here. > 7. support to thirdparty products Depends what products you are interested in. > 8. functionability Not sure what you mean here. > 9. operatability Not sure what you mean here. > 10. reliability You'd hope all would be reliable on good hardware. Sorry if this isn't as much help as you'd like, but you'll need to give more detail if you want a more detailed answer. -- Richard Huxton Archonet Ltd
