Design
Bayani Gaba-gaba
Once the analyst knows what the new system must do, the next stage is to design it on paper before anyone builds it. Design is where the shape of the data, the look of the screens and printouts, and the rules that keep bad data out are all decided in detail. A good design saves enormous amounts of wasted effort later, because mistakes are far cheaper to fix on a design sheet than in finished software.
In this lesson you will learn how to design file and data structures, choosing field names, lengths and data types and using codes to save space. You will design data capture forms, screen layouts and report layouts, and you will master the six validation routines (range, character, length, type, format, presence) plus the check digit, knowing exactly what each one does and when to use it.
