Hi,

Can anybody tell me what are the storage engines with respect to relational databases ?

+1  A: 

Well, they are the part that actually stores data on the discs. That simple.

Thanks for your reply. But why do they categorized into InnoDB, MyISAM, etc..
Multiplexer
They are not categorized - those are DIFFERENT STORAGE ENGINES that MySQL can use. Same like a VOlkswagen and a Mercedes are different cars - not " cars categorized by mercedes and volkswagen".
TomTom
You could categorize them as "able to support RDBMS integrity" and "not able to support RDBMS integrity" (MyISAM) and "somewhere in-between" (InnoDB)...
