Model
Jurusan Teknik ElektroSemester Genap Tahun Ajaran 2014/2015
Make understanding complex systems easier (simplifies)
Can be used to design – make models of new systems so can refine them
Makes communication about systems easier (e.g. a picture can communicate a thousand words)
Why do we need models?

Information System
Jurusan Teknik ElektroSemester Genap Tahun Ajaran 2014/2015
Data:Raw facts
Information:Collection of facts
organized in such a way
that they have value
beyond the facts
themselves
Data or Information
