Thread: difference between all RDBMSs
hello sir,
i m an engineering student and i m looking out for differrences between oracle v/s sybase v/s sql v/s plsql v/s mysql with respect to the following points
1. rdbms
2. data independence
3. support of plsql
4. integrity
5. security
6. use and application
7. support to thirdparty products
8. functionability
9. operatability
10. reliability
please reply me as soon as possible.

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

Obviously on this list you will mostly get info on PostgreSQL. With regard to PostgreSQL, I would highly suggest familiarizing yourself with the online documentation. I won't cover the weaknesses of MySQL here, but will give you a quick overview on how PostgreSQL is different from other RDBMS's so you can refine your search a bit. PostgreSQL is designed to be extremely extensible. This means that one can easily write code to add data types, procedural languages, and more with very little work. Other database managers may allow for data types to be added, but I am not aware of any others that allow you to define your own procedural langauges in any arbitrary way (Even the recent enhancements to MS SQL to give it access to .Net are not this advanced). The PostgreSQL development team has made data integrity and stability (assuming working hardware) a top priority. It is certainly a higher priority than any other open source RDBMS I have ever worked with. If you want to understand other factors that make PostgreSQL different than other RDBMS's you may want to look into differences regarding: ISO compliance (which features of SQL-99 are supported), the trigger vs. rule systems in PostgreSQL (warning MS SQL uses something they call rules but it is something different), and features like inherited tables. Again, read the online documentation. Best Wishes, Chris Travers Metatron Technology Consulting

So there isn't much time left for you to submit your homework/report?
