In thi article we preent a complete ti about oftware ifferent metho a: SPE, EBAE, SAM, LQN, ARGUSI, ALMA, ATAM, SAAM introuce a proper categorizati to compare the oftware architecture eigning ti. Thi format preen by the purpoe of imilaritie ifference icovery between architecture eigning ti metho. refore in thi article we ecie to te feature rela to oftware tructure eigning ti metho mentie above preent a framework to categorize compare them. Key term: oftware architecture, ti oftware engineering,requirement 1 INTRODUCTION: In recent year reearche about oftware architecture ha change to e of the import iue in oftware engineering. Becaue oftware architecture effect the ytem quality feature a, maintenance other iue, therefore taken ecii uring architecting ha influential effect the ytem reult. Toay oftware architecture a a oluti i ciere for high level eigning. Architecture i mae bae a collecti of inquire which houl be obvia. Thi inquiry gathere from beneficiarie like ytem applic eveloper. Any attempt to preent complete framework for categorizati oftware ti metho compari nee pat reearcher' tuie reearch reult. We try to te all oftware architecture ti metho. neceary to ay that unfortunately mot of publihe article in thi fiel ha preen a clear format about metho compari motly thee metho are publihe to upport an ti metho evelopment. oftware engineering ociety ha preen ifferent metho ofoftware architecture ti but few work ha been preen about metho compari in ytematic way icovery of imilaritie ifference exit in thee metho. One of the ie performe in thi fiel i preentati of a framework in which it ha trie to compare architecturalti metho which bae thi framework 8 ample format from oftware architecture ti metho the bai of ti technique, quality feature oftware architecture ecripti, the beneficiarie involvement in ti proce, the metho ie the capability to reue preent knowlege tati applicati valiity aement of compari metho have been. Regarle of thi fact thi tak ha it own prom for example writer have preen any precie ecripti about their format element

2 Bhu.J.RNR. Vol 3; 5, : 2015 electi i eclare their reaing clearly. We believe that an ti metho houl preent more feature, 1. In preen framework[2], writer ly 3 metho in aiti to compari framework they 't inclue ome import feature a architecture efiniti, architecture ecripti, upporting tool etc., that an ti metho houl be capa to cover thee feature. In performe ti in 3 a metho for oftware architecture tiwith ciering to tology ha been preen. proucti linemakenew inquirie for architecture ti metho which i reflec in the compari framework. main aim of ti in 4 i to preent for an import ti metho to compare ti metho thee are; realizati of target, citi ccentrati uner ting feature from analyi to eterminati of reult ti. In 5 more comple compari framework for icovery of imilaritie ifference in 11 ample of oftware architecture ti metho ugge which inclue more feature, unfortunately it i capa to upport mot of oftware architecture ti metho ly in thi framework the architectural ti metho were analyze bae the ting cenario. 2 architecture architecture preent a high level abtracti about oftware ytem to element form, cnecti couregrainproceor their cfigurati. Actually oftware architecture cnect the oftware ytem organizati by the ue of relati in a ytem ecribe ata between cnecti. main ccentrati in oftware architecture ito improve the oftware evelopment becaue architectural moel coul realize the tructural, behavioral complica apect of oftware preent them officially, thereforepreentthe precie reaing about the total feature,but in aiti to unerting total feature whoe target i to realize the architectural oluti i an engineering metho for moel theorie for the ctinuou iue oluti. e moel theorie lea to eiti of ucceful experience that coul be performe for imilar prom olving. Now the oftware architecture i the combinati of architectural external feature internal cnecti between them. Next point that exit in oftware realizati i the categorizati of it mean that they make a levele tructure of relati but it might that we preent ome ifferent tructure for example in great cale project, ifferent are ivie between ifferent team. Imagine that for uch y we ivie the ytem cally between the team for aher time we ivie it a ata forother team, therefore we will have ifferent tructure for a ytem ecripti. Finally the tructure architecture are inen in a ytem that thee tructure are the architectural ly will be between their external behavior feature of each element external relati. row Ta 1: a framework for oftware architecture efiniti Each architectur architectur architectur al tructure al feature al relati behavior Logic for electi 186

We trie in thi article to preent a framework for the imilaritie ifference between the ti metho that inclue feature which are uppor by many ting metho. We ue other reource like wie tuie in the fiel of oftware architecture, previou compari framework, oftware engineer' icoverie analyi to elect our framework. Before ecripti of each framework element we preent a efiniti about e of the mot import ccept in oftware architecture quality feature. Decribing the term architecture i a imple tak, maybe it i the proof that there are many efiniti which are preen in thi fiel, although many efiniti have comm feature, till there i no agreement a tar efiniti. We ue the efiniti preen by BEY coworker" oftware architecture for a program or a calculati ytem i that ytem tructure that incluethe oftware vii pecificati of each element their relati." quality feature, a oftware unneceary inquirie like inurance capability,, the capability to ue etc. accoring to the oftware quality it preent a quality that how the feature quality which i the proof of oftware pecial feature proper combinati. quality inquire that houl be provie by the oftware architecture uually are ivie in to 191

We 't proclaim to prepare a complete lit of feature that acompari framework houl have, rather we expect that thi framework i repaire in future evelope. Briefly we can name below iue a future purpoe, increae of reearche oftware ti metho which coul cier ome quality feature, increae of invetigati ti metho which are applie frequently by reearcher cfirme. Preentati of a comprehenive compari framework coul upport mot of oftware architectural ti. 195
