ORACLE installation - instance - database

Can anybody please tell me the relationship between installations, instances
and databases?


Is it 1 to 1 to 1?


Or can multiple databases be created from a single installation or instance?
Is an instance the same as an installation?
Is a database the same as an instance?


What defines them?



ORACLE talk about a 'database system' comprising more than one database. Do
they mean


databases that have been created on the same node from different
installations?



Thanks in advance
