Difference between Top down and bottom up approaches for a
given project ?

Answer Posted / reejusri

These are two design approaches, which can be explained as:
You can imagine a tree like structure , in which when you
are following top-down appoarch you move from root node to
leaf node and when you follow bottom-up apprach you follow
leaf node to root node.

Top-down approach:
In this an overview of the system is first formulated,
specifying but not detailing any first-level subsystems.
Each subsystem is then refined in yet greater detail,
sometimes in many additional subsystem levels, until the
entire specification is reduced to base elements.

Bottom-up approach:
In this approach the individual base elements of the system
are first specified in great detail. These elements are
then linked together to form larger subsystems, which then
in turn are linked, sometimes in many levels, until a
complete top-level system is formed.
