Relational databases yog cov chunks ntawm cov ntaub ntawv cuam tshuam feem ntau nkag mus ua ke. Kev piav qhia: Cov ntaub ntawv sib raug zoo yog ib hom database uas peb tuaj yeem nkag mus rau cov ntaub ntawv uas cuam tshuam. Kev sib raug zoo database yog raws li tus qauv kev sib raug zoo uas yog cov ntaub ntawv tsim nyog.
Cov ntaub ntawv luam tawm hauv NoSQL yog dab tsi?
Replication: Replication luam cov ntaub ntawv hla ntau lub servers, yog li txhua cov ntaub ntawv tuaj yeem pom nyob rau ntau qhov chaw. Replication tuaj nyob rau hauv ob daim ntawv, Master-slave replication ua rau ib tug ntawm daim ntawv tso cai daim ntawv uas lis sau thaum qhev synchronize nrog tus tswv thiab yuav lis nyeem.
Qhov twg columnar database uas khiav ntawm pawg Hadoop?
HBase yog ib kab-oriented non-relational database management system uas khiav saum Hadoop Distributed File System (HDFS).
Dab tsi yog piv txwv ntawm hom tseem ceeb ntawm NoSQL Datastore?
Key-Value khw muag khoom yog qhov tseem ceeb tshaj plaws thiab thawj cov khw muag khoom yuav tsum tau tsim. Cov piv txwv ntawm cov khw muag khoom tseem ceeb yog: Amazon dynamo, memcachedb, voldemort, redis thiab riakQib plaub ntawm NoSQL datastores yog Graph Oriented cov khw muag khoom. Cov no yog cov chaw khaws ntaub ntawv tshiab tshaj plaws.
NoSQL yog dab tsi thiab nws hom?
NoSQL yog lub ntsiab lus rau pib lwm txoj hauv kev rau cov tsoos SQL databases NoSQL databases yog txhua yam txawv ntawm SQL databases. Lawv txhua tus siv cov qauv ntaub ntawv uas muaj cov qauv sib txawv dua li cov qauv kab-thiab-kab kab lus siv nrog kev sib raug zoo database tswj systems (RDBMSs).
