High Level Design, means precisely that. A high level
design discusses an overall view of how something should
work and the top level components that will comprise the
proposed solution. It should have very little detail on
implementation, i.e. no explicit class definitions, and in
some cases not even details such as database type
(relational or object) and programming language and
platform.
A low level design has nuts and bolts type detail in it
which must come after high level design has been signed off
by the users, as the high level design is much easier to
change than the low level design.
