Description
Inlessthanadecadeofexistence,theWebhasreachedatrulystaggeringstage, demonstratedbythescope,thereach,andthesizeofWeb-basedapplications andactivities. Concentratinginitiallyoninformationdissemination,thescopeof theapplicationsisnowlimitedonlybyourimagination. Thereachisconstantly expandingandsoarethenumberandsizeoftheapplications,alongwiththe underlyingcomplexity,rangeofpurposes,andthetimeneededtodevelopand maintainthem. Atthesametime,thedevelopmentandmaintenanceprocesses ofWebapplicationshavenotprogressedatasu?cientlyrapidpacetomeetthese challengesanddemands. Consequently,thelikelihoodisthatWebapplication developmentwillgetintoacrisisanditisnothardtoimaginethatthiswould dwarfthe'softwarecrisis'identi?edlongagointhe1960s. WebEngineeringaimstoavertthispotentialcrisisbygeneratingaproactive approachtothesuccessfuldevelopmentofWeb-basedsystemsandapplications. WebEngineeringinvolvestheuseofscienti?c,engineering,andmanagement principlesandsystematicapproacheswiththeaimofsuccessfullydeveloping, deploying,andmaintaininghighqualityWeb-basedsystemsandapplications. WebEngineering,initscurrentform,isanearlyattempttoidentifythes- ni?cantissuesandproblems,andtheirsolutions,indevelopingWeb-basedapp- cations.
