PLAN IS EXECUTABLE AND PACKAGE IS NOT EXECUTABLE . THEN WHAT IS THE USE OF PACKAGE?..

See there is not doubt that PLAN is an executable form of
DBRM and package is not the executable form.
Basically a DBRM can be linked to PLAN directly or a DBRM
can be linked to Package and that package can further linked
to the PLAN
Now if we directly link the DBRM with the plan then every
time we recompile the program(DBRM) we have to regenerate
the plan.
Whereas if we link the DBRM via package then every time we
recompile the program(DBRM) we only require to recompile the
Package.
Hence Binding through package prevents regeneration of plan.

1 more line I want to add just for knowledge.
If we regenerate the PLAN every time then all the other
Programs(DBRMs) which are attached to that same PLAN
required to be rebind thus take waste time.

Hope this answers your query...
