Injini yogcino-lwazi isebenza njengondoqo weenkqubo zolawulo lwedatha, inoxanduva lokulawula nokulawula ukufikelela kwidatha, kunye nokuqinisekisa ukuhambelana kwayo nokungaguquguquki. Ngobuchule bokuphucula kunye ne-algorithms ephezulu, iinjini zedatha zivumela imibuzo enzima ukuba yenziwe ngokufanelekileyo, ukonga ixesha kunye nezixhobo.

Kubalulekile ukuqaphela ukuba kukho iintlobo ezahlukeneyo zeenjini zedatha, nganye yenzelwe ukuhlangabezana neemfuno ezithile. Ukusuka kwiinjini zobudlelwane bemveli ukuya kwezona njini zanamhlanje zeNoSQL, nganye ibonelela ngezinto eziluncedo nezingeloncedo ngokuxhomekeke kumxholo kunye neemfuno zeprojekthi.

Ngamafutshane, i-injini yedatha yinxalenye esisiseko kwiziseko zophuhliso lwetekhnoloji yangoku. Ukukwazi kwayo ukulawula umthamo omkhulu wolwazi kunye nokubonelela ngeempendulo ezikhawulezayo kwimibuzo kwenza kube sisixhobo esiyimfuneko kuwo nawuphi na umbutho okanye inkampani efuna ukwandisa ulawulo lwayo lwedatha ngokufanelekileyo nangempumelelo.
