DFD's!

today, what we'd learnt in class is about how to do DFD(data-flows-diagrams)

at first, it was something hard to do because we don't understand what the DFD actually,

but after do some exercise. now we know how to do the DFD.

basically DFD have 2 definitions :-

1) Context diagram

2) Level-O diagram

the differences between context diagram and level-O diagram are,

level-O diagram has more details in process rather than context diagram..

thanks to our lecturer for commenting what we had done :)
