Buzzword Buster – Cross-Cutting Concern

Def­i­n­i­tion: A Cross-Cut­t­ing Con­cern is a con­cern your appli­ca­tion needs to address that is unre­lat­ed to your application’s prob­lem domain, and ‘cuts across’ oth­er con­cerns. Typ­i­cal exam­ples include: log­ging per­sis­tence secu­ri­ty error han­dling They are usu­al­ly dif­fi­cult to decom­pose from the rest of the sys­tem and result in tan­gled code. Address­ing these cross-cut­t­ing con­cerns will …

Buzzword Buster — DSL

Def­i­n­i­tion: A Domain Specif­ic Lan­guage (DSL) is a pro­gram­ming lan­guage that’s ded­i­cat­ed to a par­tic­u­lar prob­lem domain. DSLs are often used to sup­port domain-dri­ve design and mod­el­ling. It’s the oppo­site of gen­er­al pur­pose pro­gram­ming lan­guages such as C# or Java. Advan­tages: Code looks like domain prose. Eas­i­er to under­stand by every­one. Eas­i­er to align with …

Buzzword Buster — Dependency Inversion Principle

Def­i­n­i­tion: Depen­den­cy Inver­sion Prin­ci­ple refers to a spe­cif­ic form of decou­pling aimed at rend­ing high-lev­­el mod­ules inde­pen­dent of the low-lev­­el mod­ules’ imple­men­ta­tion details. Its prin­ci­ple states: High-lev­­el mod­ules should not depend on low-lev­­el mod­ules, both should depend on abstrac­tions. Abstrac­tions should not depend upon details. Details should depend upon abstrac­tions. Depen­den­cy Inver­sion Prin­ci­ple is often …

Buzzword Buster — Spaghetti Code

Def­i­n­i­tion: You have Spaghet­ti code when the flow in your appli­ca­tion becomes so com­plex and tan­gled it resem­bles a bowl of spaghet­ti where the dif­fer­ent exe­cu­tion paths are twist­ed and inter­twined it’s hard to make out where they start and end. In soft­ware design, this is usu­al­ly a dan­ger asso­ci­at­ed with pro­ce­dur­al pro­gram­ming or fre­quent, …

Buzzword Buster – Macaroni Code

Def­i­n­i­tion: You have Mac­a­roni code when your appli­ca­tion is chopped up into many lit­tle pieces and it’s dif­fi­cult to see the big pic­ture which may exist only in your (or some­one else’s!) head. In soft­ware design, you can often end up with Mac­a­roni code when you overuse/misuse/abuse abstrac­tions, and it’s one of the main dan­gers …

Buzzword Buster — IoC

Def­i­n­i­tion: Inver­sion of Con­trol (IoC) refers to the inver­sion of the flow of con­trol (the order in which indi­vid­ual state­ments, func­tion calls, etc. are exe­cut­ed) in a soft­ware. You’ll often hear the term Hol­ly­wood prin­ci­ple being men­tioned in the same breath as IoC, it sim­ply states “Don’t call us, we’ll call you” which more or …

Buzzword Buster — Forewords

For many of us, buzz­words and jar­gons have become part of every­day life, and us I.T (yet anoth­er for­mer buzz­word..) pro­fes­sion­als nev­er seem to shy away from the chance to invent new buzzwords/abbreviations to add to our ever-expand­ing vocab­u­lary of tech­ni­cal terms used in I.T talks which con­fus­es those not in the know to no …
