Re: Difference Between DBMS/RDBMS

[Alexandre Gorbatchev]

OK. First were pre-relational DBMS. Like fms, network, hierarchical; programmatic & pragmatic. Different types. Some are still useful. Than Codd came with his 12 rules (12?) I believe INGRES was the fist one based on his research. Than (80's) came Oracle, Sybase, DB2, Informix. btw, I believe Oracle was not relational until version... mmm 6 or 7? was 6 relational? Than came post-relational dbms with extended semantic, rule-based, etc. 90's - object oriented DB, spatial, distributed db, multi-dimensional, data warehouses and data mining, AI. about 2000 came XML   They all seem to be DMBS, but not all are RDBMS. In fact, can anybody name pure relational dbms?   What did I forget, missed or make wrong? ----- Original Message ----- From: Santosh Varma To: Multiple recipients of list ORACLE-L Sent: Tuesday, June 25, 2002 2:18 PM Subject: RE: Difference Between DBMS/RDBMS full form i also knew. and also that all dbms have the features of rdbms also then, what is the difference ??   santosh -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Marcello Savino Sent: Tuesday, June 25, 2002 4:58 PM To: Multiple recipients of list ORACLE-L Subject: R: Difference Between DBMS/RDBMS DBMS =Data Base Management System RDBMS=Relational Data Base Management System But actually i do not know any dbms that's not an rdbms.
