Kev rov ua dua ntawm tus tswv thiab qhev muaj qhov sib txawv hauv cov oplogs, ua rau cov qhev tsis muaj cov ntaub ntawv uas tus tswv muaj. Yog, tsis muaj checksum, thiab yog, cov xwm txheej replication muaj cov qhev tam sim no.
Tom qab, lo lus nug yog, MongoDB yog NoSQL?

Hauv kev xyaum ua lag luam feem ntau siv cov txheej txheem nruj nruj ob theem xauv (SS2PL) rau kev tswj hwm kev sib raug zoo, uas ua kom lub ntiaj teb serializability, yog tias tag nrho cov ntaub ntawv koom nrog siv nws
Dab tsi yog qhov sib txawv ntawm kev faib cov txheej txheem hauv database?
Siv cov txheej txheem kev faib cov ntaub ntawv no, databasetables tau muab faib ua ob txoj hauv kev: ib leeg-theem partitioning thiab composite partitioning. Cov txheej txheem yog: Hash Partitioning. Range Partitioning. List Partitioning
