Ngati mungatsegule zitsimikiziro zolowera popanda kupanga akaunti yoyamba, ndiye kuti sititha kulumikizana ndi ntchito ya mongodb. Mu chitsanzo chotsatira, timapanga akaunti ndi akaunti my_account ndichinsinsi my_password, ndikuvomereza ngati woyang'anira nkhokwe.

            use admin;

Fayilo yosungira nkhokwe ya mongodb ndi mafayilo angapo omwe amasungidwa m'ndandanda, ndipo zosunga zobwezeretsera zamtundu wachinsinsi zomwe timakonda kugwiritsa ntchito ndimafayilo odziyimira pawokha. Chifukwa chake, zosunga zobwezeretsera zikamalizidwa, nthawi zambiri timafunikira kuti tizipondereze kukhala fayilo yapadera yokhala ndi chida chopondereza kenako ndikutsitsa ndikusamutsa. Chotsatira ndi chitsanzo chothandizira ndikubwezeretsanso nkhokweyo.
