Sharding yog ib txoj hauv kev los faib cov ntaub ntawv hla ntau lub tshuab. MongoDB siv sharding los txhawb kev xa tawm nrog cov ntaub ntawv loj heev thiab kev ua haujlwm siab dhau los. Database cov tshuab nrog cov ntaub ntawv loj lossis cov ntawv thov nkag siab tuaj yeem sib tw lub peev xwm ntawm ib tus neeg rau zaub mov.
Ib yam li ntawd, tib neeg nug, MongoDB puas yog cov khoom taw qhia cov ntaub ntawv?
MongoDB yog ib khoom - taw qhia , yooj yim, dynamic, thiab scalable NoSQL database . Nws yog raws li NoSQL cov ntaub ntawv khw qauv. Cov ntaub ntawv khoom tau muab khaws cia raws li cov ntaub ntawv sib cais hauv ib qho kev sau - es tsis txhob khaws cov ntaub ntawv rau hauv kab thiab kab ntawm ib txwm muaj kev sib raug zoo database.
Qhov thib ob, kev siv MongoDB database yog dab tsi? MongoDB yog cov ntaub ntawv-oriented database uas khaws cov ntaub ntawv hauv JSON-zoo li cov ntaub ntawv nrog dynamic schema. Nws txhais tau tias koj tuaj yeem khaws koj cov ntaub ntawv yam tsis muaj kev txhawj xeeb txog cov ntaub ntawv cov qauv xws li cov lej ntawm cov teb lossis hom teb los khaws cov nqi. MongoDB cov ntaub ntawv zoo ib yam li JSON cov khoom.
Ib yam li ntawd, MongoDB puas zoo rau kev lag luam database?
Hauv nws qhov tseem ceeb, MongoDB yog ib daim ntawv database thiab - yuav luag los ntawm lub neej ntawd - cov hom no databases tsis ua raws li ACID, tshwj xeeb tshaj yog thaum nws los txog rau ntau cov ntaub ntawv kev lag luam (ntawm cov ntaub ntawv qib, MongoDB twb txhawb ACID kev lag luam ).
Cov ntaub ntawv khaws cia nyob qhov twg hauv MongoDB?
Los ntawm lub neej ntawd, MongoDB mloog rau kev sib txuas los ntawm cov neeg siv khoom ntawm chaw nres nkoj 27017, thiab khw muag khoom cov ntaub ntawv hauv / cov ntaub ntawv /db directory. Yog koj xav mongod khaws cia cov ntaub ntawv cov ntaub ntawv ntawm txoj kev uas tsis yog / cov ntaub ntawv / db koj tuaj yeem qhia qhov dbPath. Lub dbPath yuav tsum muaj ua ntej koj pib mongod.

Puas yog TIFF cov ntaub ntawv yog cov ntaub ntawv vector?
TIF - (los yog TIFF) sawv cev rau Tagged Image File Format thiab yog cov ntaub ntawv loj loj. Cov ntaub ntawv TIF feem ntau yog siv rau cov duab hauv kev luam ntawv vim tias cov ntaub ntawv tsis poob cov ntaub ntawv lossis zoo li JPEG ua. Nws yog cov ntaub ntawv vector uas tuaj yeem muaj cov ntawv nyeem nrog rau cov duab thiab cov duab kos
Dab tsi yog cov txheej txheem kev faib tawm hauv cov ntaub ntawv mining?
Cov ntaub ntawv mining suav nrog rau 6 chav kawm ua haujlwm. Anomaly detection, Association txoj cai kawm, Clustering, Classification, Regression, Summarization. Kev faib tawm yog cov txheej txheem loj hauv cov ntaub ntawv tsuas thiab siv dav hauv ntau yam
Thaum cov lus tau hla tawm cov ntaub ntawv kuaj xyuas feem ntau nthuav tawm cov ntawv sau thawj nrog kev pab ntawm dab tsi?
Infrared luminescence yog siv rau: Qhia tawm cov ntawv sau uas tau muab tshem tawm THIAB kuaj pom yog tias ob tus lej sib txawv tau siv rau hauv kev sau ntawv. Cov kws tshuaj xyuas cov ntaub ntawv feem ntau nthuav tawm cov ntawv sau thawj ntawm cov lus uas tau hla nrog kev pab ntawm: Infrared tawg
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
Dab tsi yog kev siv lub sij hawm teev cov txheej txheem hauv cov ntaub ntawv faib tawm?
Timestamp-based Protocols Lub timestamp-based algorithm siv lub sijhawm sau npe los ua kom tiav qhov kev ua tiav ntawm kev sib pauv hloov pauv. Cov txheej txheem no ua kom ntseeg tau tias txhua qhov kev nyeem ntawv tsis sib haum xeeb thiab sau ntawv ua haujlwm raug ua raws li lub sijhawm teev tseg. Cov txheej txheem siv lub Sijhawm Sijhawm lossis Lub Sijhawm Logical suav nrog Timestamp
