Qhov Tseem Ceeb Qhov txawv - NoSQL vs MongoDB
Txoj kev tswj hwm cov ntaub ntawv sib txuas (RDBMS) yog siv los ntawm ntau lub koom haum. Structured Query Language (SQL) yog siv los khaws, khaws thiab hloov kho cov ntaub ntawv hauv cov ntaub ntawv sib txheeb. Lawv tsis ua haujlwm zoo hauv kev khaws cia ntau yam ntawm cov ntaub ntawv, thiab nws nyuaj rau ua kab rov tav scaling. Yog li ntawd, NoSQL tau qhia. NoSQL sawv cev rau "Tsis yog SQL nkaus xwb" lossis "Tsis muaj SQL." Muaj ntau hom NoSQL databases xws li cov ntaub ntawv, tus nqi tseem ceeb, daim duab, thiab lwm yam MongoDB yog hom NoSQL. Nws yog ib qho yooj yim siv, qhib qhov software sau hauv C ++ uas yog ceev thiab hloov tau. Qhov sib txawv tseem ceeb ntawm NoSQL thiab MongoDB yog NoSQL yog ib lub tswv yim los khaws thiab khaws cov ntaub ntawv hauv cov ntaub ntawv tsis muaj feem cuam tshuam thiab MongoDB yog cov ntaub ntawv-taw qhia cov ntaub ntawv uas belongs rau NoSQL.
NoSQL yog dab tsi?
Muaj ntau cov databases xws li MySQL, Oracle, thiab lwm yam. Cov databases no hu ua Relational Databases. Cov ntaub ntawv sib raug zoo muaj cov rooj, thiab lawv muaj feem cuam tshuam nrog kev txwv xws li Primary Key, Foreign Key. Relational databases tsis zoo hauv kev khaws cov ntaub ntawv loj / Cov ntaub ntawv loj. Cov ntaub ntawv loj yog cov ntaub ntawv loj uas nyuaj rau khaws cia siv cov khoom siv ib txwm siv lossis cov ntaub ntawv sib raug zoo.
NoSQL sawv cev rau cov ntaub ntawv tsis muaj feem cuam tshuam thiab tuaj yeem ua cov ntaub ntawv loj. Tsis tas li, nws yooj yim los tswj cov NoSQL databases. Cov ntaub ntawv tuaj yeem scaled tawm los yog pawg rau hauv cov tshuab. Clustering txo tus nqi ntawm kev tswj cov ntaub ntawv. Muaj ntau hom NoSQL databases. Cov ntaub ntawv databases siv rau cov ntaub ntawv dynamic. Cov ntaub ntawv zoo li no yog MongoDB thiab Couch DB. Hauv cov ntaub ntawv no, cov ntaub ntawv khaws cia hauv daim ntawv ntawm JavaScript Object Notation (JSON) hom.
Lwm hom yog Kem databases. Ib qho piv txwv yuav yog Apache Cassandra. Hauv kev sib raug zoo databases, cov ntaub ntawv yog nyeem thiab sau kab vise. Tab sis nyob rau hauv kem databases, cov ntaub ntawv nyeem thiab sau ntawv yog ua ke kem-wise. Qhov no muaj txiaj ntsig zoo rau kev txheeb xyuas cov ntaub ntawv.
Daim duab - NoSQL databases
Ib hom NoSQL database yooj yim yog Qhov Tseem Ceeb-Value khaws cia databases zoo li Couchbase Sever, Redis. Lawv yog ceev tab sis tsis heev customizable. Cache databases tuaj yeem khaws cov ntaub ntawv rau hauv disk lossis cache. Ib qho piv txwv ntawm lub cache database yog Memcache. Graph databases muaj cov nodes thiab kev sib raug zoo yog tsim los ntawm cov npoo. Neo4J thiab Oracle NoSQL yog ib co ntawm cov duab databases.
MongoDB yog dab tsi?
MongoDB yog cov ntaub ntawv qhia txog cov ntaub ntawv. Nws yog qhib qhov software. Cov ntaub ntawv sib raug zoo muaj cov ntxhuav, thiab cov ntxhuav muaj kab thiab kab. Ib yam li ntawd, MongoDB muaj cov ntawv sau thiab cov ntaub ntawv. Ib daim ntawv yog cov ntaub ntawv hauv MongoDB sau. Kev sau yog ib txheej ntawm MongoDB cov ntaub ntawv. Feem ntau, txhua cov ntaub ntawv muaj lub hom phiaj zoo sib xws. Ib tus neeg rau zaub mov MongoDB muaj ntau lub databases. 'mongod.exe' yog lub database server thiab 'mongo.exe' yog lub plhaub sib tham.
Tus programmer sau cov ntaub ntawv hauv JSON hom. MongoDB sab hauv hloov JSON cov khoom raug hloov mus rau BSON. BSON yog binary khoom thiab muaj cov lus hais hauv ob qho tseem ceeb thiab tus nqi. MongoDB yog qhov muaj txiaj ntsig yog agile raws li software txhim kho vim nws tuaj yeem hloov mus rau ntau cov ntaub ntawv. Nws yog ib qho yooj yim los hloov cov ntaub ntawv los ntawm kev yooj yim ntxiv thiab tshem tawm cov uas twb muaj lawm. MongoDB tuaj yeem khaws cov ntaub ntawv sib txawv xws li txoj hlua, tus lej, hnub tim, array, Booleans, thiab lwm yam. Nws kuj muaj cov ntaub ntawv tsis sib xws rau khaws cia video, duab, thiab suab. Cov ntaub ntawv sib xyaw tuaj yeem sib xyaw cov ntaub ntawv sib txawv. MongoDB muaj cov syntax yooj yim, yog li nws yooj yim los sau cov lus nug. Nws tseem tuaj yeem muab cov phiaj xwm txo qis hauv kev faib khoom vaj tsev.
Dab tsi yog qhov zoo sib xws ntawm NoSQL thiab MongoDB?
- Ob leeg tuaj yeem ua Cov Ntaub Ntawv Loj.
- Txhawb kab rov tav scalability yam tsis muaj khoom kim heev.
- Txhawb kev faib khoom architecture.
- Ob leeg tsis txhawb koom.
- Ob leeg tsis tuaj yeem ua haujlwm nyuaj.
- Tus schema yog dynamic.
- Yooj yim thiab siv tau yooj yim.
Qhov txawv ntawm NoSQL thiab MongoDB yog dab tsi?

Summary – NoSQL vs MongoDB
NoSQL databases muaj cov qauv faib thiab tuaj yeem ua kom cov ntaub ntawv sib xws. MongoDB yog qhov qhib NoSQL database. Nws muab scalability thiab kev ua haujlwm siab. Hauv kev txhim kho agile, cov kev xav tau tuaj yeem hloov pauv, thiab MongoDB tso cai rau hloov cov schema. Qhov txawv ntawm NoSQL thiab MongoDB yog tias NoSQL yog ib lub tswv yim los khaws thiab khaws cov ntaub ntawv hauv cov ntaub ntawv tsis muaj feem cuam tshuam thiab MongoDB yog cov ntaub ntawv-oriented database uas belongs rau NoSQL.
