METODE PEMODELAN PERANCANGAN TERSTRUKTUR

• Functional Design
• Berorientasi pada fungsi
• Structured Design (Constantin & Yourdon, 1979), Step wise

  Refinement (Wirth, 1971, 1976), Jackson Structured

  Programming (Jackson, 1975), dll.

FUNCTIONAL DESIGN APPROACHES

• langkah perancangan untuk tipe DFD
• Transform Mapping

  transform flow

• Incoming flow : aliran/jalur informasi eksternal masuk ke sistem untuk ditransformasikan menjadi informasi internal
• Transform center : pusat transformasi di dalam sistem yang akan mentriger informasi keluar dari system
• Outgoing flow : aliran/jalur informasi internal keluar dari sistem menjadi informasi eksternal
• langkah perancangan untuk tipe DFD
• Transaction Mapping

  transaction flow

• Transaction : data tunggal yang mentriger satu atau beberapa aliran data
• Transaction center : penghubung antara aliran-aliran data hasil pentrigeran dengan data trigernya
• Action path : aliran/jalur informasi hasil triger

TRANSFORM MAPPING

• Langkah-langkah Transform Mapping
• Incoming flow : aliran/jalur informasi eksternal masuk ke

• Review dan refine DFD sampai ke level paling bawah

• Tentukan apakah DFD tsb. memiliki karakteristik tipe

  transform flow atau transaction flow
• Tentukan batas antara incoming flow, transform center dan outgoing flow
• Bangun first level factoring
• Bangun second level factoring
• Refine first iteration
• Contoh Transform Mapping : SafeHome Security Software
