Thawj qhov kev tshaj tawm pej xeem ntawm MangoDB qhov project yog muaj, muab ib txheej nrog kev siv ntawm MongoDB cov ntaub ntawv-oriented DBMS raws tu qauv khiav rau saum PostgreSQL DBMS. Qhov project aims los muab lub peev xwm mus tsiv teb tsaws daim ntaub ntawv siv MongoDB DBMS rau PostgreSQL thiab ib tug kiag li qhib software pawg. Cov cai tau sau rau hauv Go thiab faib raws li Apache 2.0 daim ntawv tso cai.
Qhov kev zov me nyuam ua haujlwm ua tus neeg txhais lus hu rau MangoDB rau hauv SQL queries rau PostgreSQL, siv PostgreSQL raws li qhov tseeb cia. Qhov project yog sib xws nrog cov tsav tsheb rau MongoDB, tab sis tseem nyob rau theem qauv thiab tsis txhawb nqa cov yam ntxwv siab ntawm MongoDB raws tu qauv, txawm hais tias nws twb tsim nyog rau kev txhais cov ntawv yooj yim.
Qhov xav tau kom tsis txhob siv MongoDB DBMS tuaj yeem tshwm sim vim qhov kev hloov pauv ntawm txoj haujlwm mus rau qhov tsis pub dawb SSPL daim ntawv tso cai, uas yog raws li daim ntawv tso cai AGPLv3, tab sis tsis qhib, vim nws muaj kev ntxub ntxaug rau kev muab raws li daim ntawv tso cai SSPL. tsis tsuas yog daim ntawv thov code nws tus kheej, tab sis kuj yog cov cai ntawm txhua qhov chaw koom nrog hauv kev muab kev pabcuam huab.
Nco qab tias MongoDB tuav lub niche ntawm ceev thiab scalable systems uas ua hauj lwm ntawm cov ntaub ntawv nyob rau hauv cov ntaub ntawv tseem ceeb / tus nqi hom, thiab kev sib raug zoo DBMS, haumxeeb thiab yooj yim nyob rau hauv tsim queries. MongoDB txhawb nqa cov ntaub ntawv khaws cia hauv JSON-zoo li hom lus, muaj cov lus hloov tau yooj yim rau kev tsim cov lus nug, tuaj yeem tsim cov indexes rau ntau yam khaws cia, muaj txiaj ntsig zoo muab khaws cia ntawm cov khoom loj binary, txhawb kev txiav cov haujlwm los hloov thiab ntxiv cov ntaub ntawv rau hauv cov ntaub ntawv, tuaj yeem ua haujlwm raws li daim ntawv qhia paradigm / Txo, txhawb kev rov ua dua thiab tsim cov teeb tsa tsis raug cai.
