Top down analysis is a problem solving mechanism whereby a given problem is successively broken down into smaller and smaller sub-problems or operations until a set of easily solvable (by computer) subproblems is arrived at.Each level is numbered commencing with the top (first) level followed by the second level and so on.The designer ends up with very large tree structures.
