Lub hom phiaj ntawm kev siv a NoSQL database yog rau faib cov ntaub ntawv khaws cia nrog humongous data storage xav tau. NoSQL database stands rau "Tsis yog SQL" lossis "Tsis yog SQL." Txawm hais tias lub sijhawm zoo dua yuav NoREL NoSQL ntes tau.
Tsis tas li ntawd, NoSQL database piv txwv yog dab tsi?
Cov ntaub ntawv raws li database khaws cov ntaub ntawv ua los ntawm cov khoom tagged. Piv txwv : MongoDB, CouchDB, OrientDB, thiab RavenDB. Txhua qhov thaiv cia muaj cov ntaub ntawv los ntawm ib kab xwb, Piv txwv : BigTable, Cassandra, Hbase, thiab Hypertable. Ib tug graph-based database yog lub network database uas siv nodes sawv cev thiab khaws cov ntaub ntawv.
Qhov thib ob, NoSQL database zoo rau dab tsi? NoSQL databases yog lub hom phiaj tsim rau cov qauv ntaub ntawv tshwj xeeb thiab muaj cov qauv siv tau yooj yim rau kev tsim cov ntawv thov niaj hnub. NoSQL databases tau dav lees paub rau lawv qhov yooj yim ntawm kev txhim kho, kev ua haujlwm, thiab kev ua haujlwm ntawm qhov ntsuas. Lawv siv ntau yam qauv ntawm cov ntaub ntawv, nrog rau cov ntaub ntawv, daim duab, thiab tus nqi tseem ceeb.
Tom qab, lo lus nug yog, NoSQL database txhais li cas?
A NoSQL (Keeb kwm hais txog "tsis yog SQL" lossis "tsis muaj kev sib raug zoo") database muab ib tug mechanism rau cia thiab retrieval cov ntaub ntawv uas yog ua qauv hauv txhais tau tias lwm yam tsis yog kev sib raug zoo tabular siv hauv kev sib raug zoo databases . NoSQL databases yog nce siv nyob rau hauv cov ntaub ntawv loj thiab cov ntawv thov lub vev xaib tiag tiag.
Dab tsi yog qhov sib txawv ntawm NoSQL databases?
Muaj plaub loj NoSQL hom : key-value store, document store, kem-oriented database , thiab graph database . Txhua hom daws qhov teeb meem uas daws tsis tau nrog kev sib raug zoo databases . Kev siv tiag tiag feem ntau yog kev sib txuas ntawm cov no. OrientDB, piv txwv li, yog ntau hom database , kev sib txuas NoSQL hom.
