Fusebox 3 Development Methodology : www. fusebox. org The Fusebox Philosophy There are two ways of constructing a software design: • One way is to make it so simple that there are obviously no deficiencies, • and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. C. A. R. Hoare More on Fusebox at www. halhelms. com

Fusebox 3 Development Methodology : www. fusebox. org The map file : fbx_Circuits. cfm Provides a map to the location of each circuit • Each circuit has a unique name • index. cfm? fuseaction=circuit. Name. fuse. Action • Fusebox. Circuits. <circuitname> More on Fusebox at www. halhelms. com
Fusebox 3 Development Methodology : www. fusebox. org The fusebox : fbx_Switch. cfm • Just the <cfswitch> from FB 2’s index. cfm • Every circuit has one • Switches on Fusebox. fuseaction • Includes fuses to perform particular action More on Fusebox at www. halhelms. com
Fusebox 3 Development Methodology : www. fusebox. org The building blocks : Fuses Official • dsp_ : HTML display – coded by HTML coder • act_ : CFML logic – coded by CF coder • qry_ : DB interaction – coded by DBA (Query. Sims) Unofficial • url_ : sometimes used for conditional redirections • lay_ : prefix for layout files. More on Fusebox at www. halhelms. com
