Mario, do you know
what is SDLC?
That is easy,
the system development life cycle is a
series of recommended steps or phases
designed as a guideline as to what you
should be doing and when you should be
doing. This system is quite flexible and
some organizations simplify the system
development life cycle by combining
some of the phases.
I dont know, try ask that
genie.
