Hi all... How detailed should be the sequence diagrams ?? Should we show the Bussiness tier patterns, presentation tier patterns in the sequence diagrams.. becoz I know that we need to identify the objects first, draw the sequence diagrams and draw the class diagrams from the sequence diagrams... we need to show the patterns in the class diag... so should we show the Value objects, facade, DAo and stuff in sequence diag also... if yes then the seq diag will be very detailed... Stuck on this !!!
