Moving to design,
everybody is so busy with assignment, so am I...that's why this week blog is posted this time
many things have to be considered when designing new system; one is from now on the assumption of the perfect technology is no longer valid so all the possibilities of failure should be considered & the system should be designed in a way that it can be up & running all the time (that's not written anywhere- that's what I'm guessing).
the design phase consists of many parts:
designing application architecture
designing the network
designing the system & user interface
designing the database
again the system can be designed in Traditional & OOA, each has its own diagrams. the most important thing in design phase is application development. the definitions should be clarified by end of this phase.
to avoid coding many times, or to avoid changing code in different places in the system, applications are made in 3 different interrelated but independent layers i.e. view layer, business logic & data layer.

Good guessing, spot on about design.
