HLD - High Level Design
HLD is nothing but, heirarchy of all possible functionality
as module in the application.
eg. flograph, flochart, data structure.
LLD - Low Level Design
LLD is nothing but, static logic bet. every sub module.
eg. ER Diagram, Algorithm

Am specifying my answer
with an example
suppose any one goes on
gmail and put there id n
password ..when you entered
in home page it's called hld..
LLD-
when you have enter in gmail and
there is lots of internal links i.e
called low level..because when u open urs orkut account
thru gmail so when u logout yours gmail orkut will b
automatically off but when you login saperalty orkut and
saparetly gmail then ....not in this case so the
combination of hld+lld=cdd cdd stands for comprehensive
design document..
