Autonomous Data Warehouse . Oracle Autonomous Data Warehouse muab ib qho yooj yim-rau-siv, tag nrho kev ywj pheej database uas ntsuas elastically, xa cov lus nug ceev ceev thiab yuav tsum tsis muaj kev tswj hwm database. Ib qho kev sib koom ua ke tag nrho, khaws cia, network thiab kev pabcuam database rau ib tus neeg xauj tsev nkaus xwb.
Ib yam li ntawd ib tug yuav nug, dab tsi yog cov ntaub ntawv autonomous?
Tag nrho-tswj huab kev pabcuam uas ua rau nws yooj yim heev rau kev muab ib cov ntaub ntawv warehouse, sai thiab yooj yim thauj khoom cov ntaub ntawv thiab nug qhov ntawd cov ntaub ntawv siv built-in web-based cov cuab yeej xws li phau ntawv sau. Oracle qhov tshwj xeeb kev ywj pheej database moj khaum ua kom muaj kev txaus siab thiab kev ruaj ntseg tsis siv neeg - tsis tas yuav tsum tau ua haujlwm ntxiv.
Ib yam li ntawd, huab autonomous yog dab tsi? Ib kev ywj pheej database yog a huab database uas siv tshuab kev kawm kom automate database tuning, kev ruaj ntseg, thaub qab, hloov tshiab, thiab lwm yam kev tswj cov hauj lwm ib txwm ua los ntawm DBAs. Tsis zoo li ib tug pa database, ib kev ywj pheej database ua txhua yam haujlwm no thiab ntau yam tsis muaj kev cuam tshuam tib neeg.
autonomous kev ua lag luam yog dab tsi?
Oracle Autonomous Transaction Processing muab kev tsav tsheb rau tus kheej, kev ruaj ntseg ntawm tus kheej, kho tus kheej cov kev pabcuam uas tuaj yeem ntsuas tam sim kom tau raws li qhov xav tau ntawm ntau yam kev siv: lub hom phiaj tseem ceeb kev ua lag luam , sib xyaw kev lag luam thiab analytics, IoT, JSON cov ntaub ntawv, thiab lwm yam.
Oracle tshuab kev kawm yog dab tsi?
Txog Oracle Machine Learning Oracle Machine Learning yog kev sib koom tes hauv web-based interface uas muab ib puag ncig kev txhim kho los tsim cov ntaub ntawv mining phau ntawv uas koj tuaj yeem ua cov ntaub ntawv txheeb xyuas, tshawb pom cov ntaub ntawv thiab cov ntaub ntawv pom. Tso cai rau kev sib koom tes ntawm cov ntaub ntawv tshawb fawb, cov neeg tsim khoom, cov neeg siv khoom lag luam.

Dab tsi yog qhov sib txawv ntawm pab pawg cov ntaub ntawv thiab cov ntaub ntawv tsis yog pawg?
Ob leeg yog cov ntaub ntawv muaj txiaj ntsig ntawm cov ntaub ntawv tab sis qhov sib txawv ntawm lawv yog cov ntaub ntawv tsis muaj ntaub ntawv yog rawdata. Qhov no txhais tau hais tias nws nyuam qhuav tau sau tab sis tsis txheeb rau hauv ib pawg lossis cov chav kawm. Ntawm qhov tod tes, groupeddata yog cov ntaub ntawv uas tau teeb tsa ua pawg los ntawm cov ntaub ntawv nyoos
Dab tsi yog cov ntaub ntawv hloov pauv hauv cov ntaub ntawv khaws cia?
Cov ntaub ntawv hloov pauv yog cov ntaub ntawv uas tau tsim nyob rau hauv daim ntawv thov kev sib ntsib, uas tsis tau khaws cia hauv cov ntaub ntawv tom qab daim ntawv thov raug txiav
Qhov chaw nyob ntawm lub cev thiab qhov chaw nyob qhov chaw nyob yog dab tsi?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU fora program hu ua Logical Address Space
Vim li cas kem taw qhia cov ntaub ntawv khaws cia ua cov ntaub ntawv nkag ntawm disks sai dua li kab qhia cov ntaub ntawv khaws cia?
Kem oriented databases (aka columnar databases) yog qhov tsim nyog rau kev ntsuas kev ua haujlwm ntau dua vim tias cov ntaub ntawv hom ntawv (kem hom) qiv nws tus kheej kom nrawm dua cov lus nug ua - scans, aggregation thiab lwm yam. Ntawm qhov tod tes, kab oriented databases khaws ib kab (thiab tag nrho nws. kab) contiguously
Kev khaws cia thiab khaws cov ntaub ntawv yog dab tsi?
Cov ntaub ntawv khaws cia thiab khaws cia, cov txheej txheem ntawm kev sau thiab khaws cov ntaub ntawv kom lawv tuaj yeem nyob thiab tso tawm kom pom ntawm kev thov. Document-retrievalsystems khaws tag nrho cov ntaub ntawv, uas feem ntau yog muab los ntawm lub npe lossis los ntawm cov lus tseem ceeb cuam tshuam nrog cov ntaub ntawv
