APS AGENDA PERKULIAHAN • Pemodelan perancangan terstruktur
T E K N I K I N F O R M AT I K A F I L K O M U B SEMESTER GENAP 2015/2016
APS 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.

APS FUNCTIONAL DESIGN APPROACHES • Transform Mapping - langkah perancangan untuk tipe DFD 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 • Transaction Mapping - langkah perancangan untuk tipe DFD 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
