Ndezvipi Data dzokuchengetera magadzirirwo mapatani
Context:Kugadzirwa kubva pasi kuenda kumusoro In Bottom-up nzira, Data Marts vari kutanga akasika kupa nhau uye analytical nezvaanogona kuti dzakananga mabhizimisi pezvakaitwa. Idzi data marts dzinogona ipapo kubatanidzwa kuti dzigadzire nzvimbo yakazara yedata. The date yokuchengetera zvinhu bhazi mapurani iri zvikurukuru Implementation of "bhazi", muunganidzwa conformed miganhu uye conformed chokwadi, izvo zviyero kuti anogoveranwa (mu imwe nzira) pakati chokwadi muna maviri kana kupfuura mashoko marts.  Kugadzirwa kwepamusoro-pasi Nzira yokumusoro-pasi yakagadzirirwa uchishandisa muenzaniso wezvinyorwa zvebhizimisi. "Mashoko e"atomu", ndiko kuti, mashoko ari padanho rakakura zvikurusa roudzame, anochengeterwa mudura roruzivo. Dimensional data marts ine data inodikanwa kune mamwe maitiro ebhizinesi kana madhipatimendi chaiwo anogadzirwa kubva mudura reruzivo.  Magadzirirwo eHybrid Data dzokuchengetera (DW) kazhinji kufanana nomusimboti uye anotaura mapurani. Zvirongwa zvekare zvinodyisa imba yekuchengetera zvinhu zvinowanzobatanidza kutarisira ukama hwevatengi uye kuronga zviwanikwa zvebhizimisi, zvichiita kuti pave nemashoko akawanda. Kuti vasimbise izvi zvakasiyana-siyana mashoko yokutevedzera, uye kufambisa bvisa kushandura mutoro muitiro, mashoko dzokuchengetera kazhinji kushandisa operative mashoko chitoro, mashoko kubva iyo parsed kupinda chaiko DW. Kuti kuderedze redundancy yedata, hurongwa hukuru kazhinji hunochengeta dhata nenzira yakajairika. Data marts nokuda kwemishumo chaiyo inogona kuvakwa pamusoro peimba yekuchengetera.  A hybrid DW Database inochengetwa yechitatu dzose chimiro kubvisa mashoko redundancy. Zvisinei, dhatabhesi yenguva dzose haishandi zvakanaka pamishumo yezvemabhizimisi apo kuenzanisa kwemaviri kunowanikwa. Zvitoro zviduku zvemashoko zvinogona kutenga mashoko kubva mudura rakasimbiswa uye kushandisa dheta rakasvinwa, rakasiyana nokuda kwematafura echokwadi uye zviyero zvinodiwa. Iyo DW inopa imwe chete tsime reruzivo kubva iyo data marts inogona kuverenga, ichipa huwandu hwakawanda hweruzivo rwebhizinesi. Iyo hybrid architecture inobvumira DW kutsiviwa ne master data management repository uko kushanda (kwete static) ruzivo runogona kugara.  Zvikamu zvekuenzanisa zveimba yedata zvinotevera hub uye spokes architecture. Iyi nzira yokuita nayo mifananidzo ndeyokugadzira zvinhu zvakasiyana-siyana, inosanganisira nzira dzakanakisisa dzokushandisa dzokuita zvinhu zvakasiyana-siyana. Data vault modhi haisi yechokwadi yechitatu fomu yakajairika, uye inoputsa mimwe yemitemo yayo, asi iri top-pasi dhizaini ine dhizaini yekumusoro. Muenzaniso wedzimba dzokuchengetera mashoko wakagadzirirwa kuva nzvimbo yokuchengetera mashoko bedzi. Hazvina kugadzirirwa kuti vashandisi vekupedzisira vawane, iyo, kana yavakwa, ichiri kuda kushandiswa kwedata mart kana nyeredzi schema-yakavakirwa nzvimbo yekuburitsa yezvinangwa zvebhizinesi.
