Computers, Computer Science The description of the current physical environment, after all references to physical and contingent factors have been removed. The aim is to understand the business logic underlying the current practices, rather than simply to model the procedures in place, regardless of their validity. Typically, references to constraints caused by geographical considerations, machine-related procedures (e.g., photocopying, data prep.), office politics, or office procedures are removed from the Current Physical DFD, leaving just the business logic. This takes place in Step 150.
Ríomhairí, Ríomheolaíocht Tuairisc ar an timpeallacht fhisiciúil reatha, tar éis gach tagairt d'fhachtóirí fisiciúla agus teagmhasacha a bhaint. Is í an aidhm atá leis ná an loighic gnó atá mar bhunús do chleachtais reatha a thuiscint, seachas samhail shimplí de na gnásanna atá i bhfeidhm a sholáthar, is cuma cé chomh bailí is atá siad. Go tipiciúil, baintear tagairtí do shriantachtaí a tharlaíonn de thoradh cúrsaí geografacha, gnásanna a bhaineann le meaisíní (e.g., fótachóipeáil, ullmhú sonraí), polaitíocht na hoifige, nó gnásanna oifige ón DFD Fisiciúil Reatha, agus ní fhágtar ann ach an loighic ghnó. Tarlaíonn sé seo ag Céim 150.
