Esihlokweni esandulele, ngihlanganise izinto eziyisisekelo ze-DATA VAULT, echaza izakhi zayo eziyinhloko nenjongo yazo. Lesi akusona isiphetho sesihloko seDATHA VAULT; sidinga ukuxoxa ngezigaba ezilandelayo zokuvela kwe-DATA VAULT.
Futhi kulesi sihloko ngizogxila ekuthuthukisweni kwe-DATA VAULT kanye nokushintshela ku-BUUSINESS DATA VAULT noma kumane ku-BUUSINESS VAULT.
Izizathu zokuvela kwe-vault yedatha yebhizinisi
Kufanele kuqashelwe ukuthi i-DATA VAULT, ngenkathi inamandla athile, ayinazo izingqinamba zayo. Enye inkinga enjalo wubunzima bokubhala imibuzo yokuhlaziya. Imibuzo iqukethe inani elibalulekile lokujoyina, okuholela kukhodi ende nenzima. Ngaphezu kwalokho, idatha efakwe ku-DATA VAULT ayikho ngaphansi kwanoma yiziphi izinguquko, ngakho-ke ngokombono webhizinisi, i-DATA VAULT ngendlela yayo emsulwa ayinalo inani eliphelele.
Kwakuwukubhekana nalezi zinkinga lapho indlela ye-DATA VAULT yanwetshwa ngayo ngezinto ezifana nalezi:
- PIT (iphuzu ngesikhathi) amathebula;
- amatafula BRIDGE;
- IZINKULUMO EZICHAZIWE.
Ake sihlolisise inhloso yalezi zakhi.
PIT amatafula
Ngokuvamile, into yebhizinisi elilodwa (HUB) ingaqukatha idatha enezilinganiso ezihlukile zokubuyekeza. Isibonelo, uma sikhuluma ngedatha eveza umuntu, singasho ukuthi ulwazi olumayelana nenombolo yocingo, ikheli, noma i-imeyili inenani lokubuyekeza eliphezulu kunegama eligcwele, imininingwane yepasipoti, isimo somshado, noma ubulili.
Ngakho-ke, lapho unquma amasathelayithi, kubalulekile ukukhumbula ukuvama kwawo kokubuyekezwa. Kungani lokhu kubalulekile?
Ukugcina izibaluli ezinamaza ahlukene okubuyekeza kuthebula elilodwa kudinga ukungeza umugqa kuthebula isikhathi ngasinye lapho isibaluli esishintshwa kakhulu sibuyekezwa. Lokhu kubangela ukwanda kwezidingo zesikhala sediski kanye nezikhathi ezinde zokubuza imibuzo.
Manje njengoba sesihlukanise amasathelayithi ngokubuyekeza imvamisa futhi singalayisha idatha kuwo ngokuzimela, sidinga ukuqinisekisa ukuthi singakwazi ukubuyisa idatha yakamuva. Ngokufanelekile, ngaphandle kokusebenzisa UKUJOYINA okungadingekile.
Ake ngichaze: isibonelo, ake sithi udinga ukubuyisa ulwazi lwakamuva (ngokusekelwe osukwini lokugcina lokubuyekeza) kumasathelayithi anamaza ahlukene okubuyekeza. Lokhu akudingi nje UKUJOYINA kuphela kodwa nemibuzo embalwa esesidlekeni (kwisathelayithi ngayinye equkethe ulwazi) ukukhetha idethi enkulu yokubuyekeza, MAX(UpdateDate). NGEJOYINA entsha ngayinye, le khodi iyakhula futhi iba nzima ukuyiqonda ngokushesha.
Ithebula le-PIT liklanyelwe ukwenza imibuzo enjalo ibe lula. Amathebula e-PIT agcwaliswa kanyekanye nokuqoshwa kwedatha entsha ku-DATA VAULT. Ithebula le-PIT:
Ngakho, sinolwazi mayelana nokufaneleka kwedatha yawo wonke amasathelayithi nganoma yisiphi isikhathi. Ngokusebenzisa amajoyinti kuthebula le-PIT, singasusa ngokuphelele imibuzo esesidlekeni, uma nje, i-PIT igcwaliswa nsuku zonke futhi ngaphandle kwezikhala. Ngisho noma kukhona izikhala ku-PIT, singathola idatha yakamuva sisebenzisa umbuzo owodwa kuphela ofakwe ku-PIT ngokwayo. Umbuzo owodwa ofakwe esidlekeni uzosebenza ngokushesha kunemibuzo efakwe kusidleke kwisathelayithi ngayinye.
IBHULA
Amathebula e-BRIDGE nawo asetshenziselwa ukwenza imibuzo yokuhlaziya ibe lula. Kodwa-ke, ahlukile ku-PIT ngoba enza lula futhi asheshise imibuzo phakathi kwamahabhu ahlukene, izixhumanisi, namasathelayithi awo.
Ithebula liqukethe bonke okhiye abadingekayo bawo wonke amasathelayithi asetshenziswa njalo emibuzweni. Ngaphezu kwalokho, okhiye bebhizinisi abasheshi bangangezwa ngokhiye bemibhalo engenalutho uma amagama abalulekile edingeka ukuze kuhlaziywe.
Iphuzu liwukuthi ngaphandle kokusebenzisa i-BRIDGE, ohlelweni lokuthola idatha etholakala kumasathelayithi asezindaweni ezihlukene, kuzodingeka UKUJOYINA hhayi amasathelayithi ngokwawo kuphela, kodwa futhi nezixhumanisi ezixhumanisa amahabhu.
Ukuba khona noma ukungabikho kwe-BRIDGE kunqunywa ukumiswa kwesitoreji kanye nesidingo sokuthuthukisa ukusebenza kombuzo. Kunzima ukuqhamuka nesibonelo samazwe ngamazwe se-BRIDGE.
I-Predefinet Derivations
Olunye uhlobo lwento olusisondeza ku-BUUSINESS DATA VAULT amathebula aqukethe amamethrikhi abalwe ngaphambilini. Lawa mathebula abaluleke ngempela ebhizinisini; aqukethe ulwazi oluhlanganisiwe ngokwemithetho ethile futhi avumela ukufinyelela okulula.
Ngokwezakhiwo, UKUDUMISA OKUQINISEKILE akuyona into engaphezu kwenye isathelayithi yehabhu elithile. Njengesathelayithi evamile, iqukethe ukhiye webhizinisi kanye nosuku irekhodi eladalwa ngalo kusathelayithi. Nokho, kulapho ukufana kuphela khona. Izibaluli ezilandelayo zale sathelayithi "ekhethekile" zinqunywa abasebenzisi bebhizinisi ngokusekelwe kumamethrikhi asetshenziswa kakhulu, abalwe ngaphambilini.
Isibonelo, ihabhu eliqukethe ulwazi mayelana nomsebenzi lingabandakanya isathelayithi enezinkomba ezifana nalezi:
- Iholo elincane;
- Iholo eliphezulu;
- Iholo elimaphakathi;
- Isamba esiqoqiwe samaholo anqwabelene, njll.
Kunengqondo ukufaka OKUNQUNYELWE OKUQUKETHWE kuthebula le-PIT lehabhu efanayo, bese ungathola kalula izingcezu zedatha yesisebenzi ngedethi ethile ekhethiwe.
IMIPHUMELA
Njengoba umkhuba ubonisa, ukusetshenziswa kweDATHA VAULT ngabasebenzisi bebhizinisi kunzima ngandlela thile ngezizathu ezimbalwa:
- Ikhodi yombuzo iyinkimbinkimbi futhi inzima;
- Ubuningi be-JOIN buthinta ukusebenza kwemibuzo;
- Ukubhala imibuzo yokuhlaziya kudinga ulwazi oluvelele lwesakhiwo se-warehouse.
Ukuze kube lula ukufinyelela kudatha, i-DATHA VAULT inwetshwa ngezinto ezengeziwe:
- PIT (iphuzu ngesikhathi) amathebula;
- amatafula BRIDGE;
- IZINKULUMO EZICHAZIWE.
Olandelayo Ngihlela ukwabelana ngalokho engikholelwa ukuthi kuwulwazi oluthakazelisa kakhulu kulabo abasebenza ne-BI. Ngizokwethula izindlela zokudala amathebula eqiniso namathebula obukhulu asuselwa ku-DATA VAULT.
Izinto zokwakha ze-athikili zisekelwe kulokhu:
- In I-Kenta Graziano, okuyinto, ngaphezu kwencazelo eningiliziwe, iqukethe imidwebo yamamodeli;
- Incwadi: “Ukwakha Indawo Yokugcina Yedatha E-Scalable Nge-DATA VAULT 2.0”;
- Isihloko .
