Home -> Community -> Mailing Lists -> Oracle-L -> Re: Difference Between DBMS/RDBMS
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?
full form i also knew.
and also that all dbms have the features of rdbms also
then, what is the difference ??
