APEX

hi guys,

i have just use oracle apex to create some report generation tools through the web. know that this is what is known as html db in the past.
however, i have not really touch oracle forms and reports before, neither have i really seen how they work.. but soemhow i feel oracle report/forms seems to be more.. then this oracle apex.
it includes integration with web services, java and pl/sql .

but i still cant really figure out what is the actual general main difference ?
is it that for oracle forms there can be some programming logic inside , whereas for apex , it is just using what is available from what oracle provides ..
i am read oracle form white paper, but seriously, i am not a very web guy. it has alot of components that i am not familiar with.

so i hope you guys can just give me a more general rough idea.

regards,
Noob.
