Imeko ulwazi kukho izinto kunye nezinto ezifuna ukugcinwa kweenkcukacha engabo. Ngoko, kwaye baqalisa ukusebenzisa kwemodeli data ezivumela, ukongeza kumsebenzi esisiseko, ukwenza lo msebenzi nge link. Kuyimfuneko ukuba ukudala naliphi na iziko ledatha. Umbutho ngokwayo Kungaba ngokomzimba okanye enengqiqo. Kwimeko yokuqala inika yokugcina kwinqanaba umatshini. Kulungile, kukho intsebenziswano ngqo kunye umsebenzisi kwi ucwangciso olufanelekileyo, apho impembelelo software ezithile. Namhlanje umsindo yemifanekiso data kakhulu esisiseko: oluneqela elinegunya, ezinobume kunye nothungelwano.
Xa imodeli data oluneqela iseti yonke lweziqalelo inobudlelwane lisekwa imithetho ethile. Izinto angamelwa njenge umthi omfusa, leyo iqulathe iindawo kwinqanaba elinye okanye omnye, zinonxibelelwano omnye komnye. A Lendawo i iseti iimpawu echaza into. umthi oluneqela iye enekona enye kuphela ilele phezu komhlaba. Loo imodeli ayikho ngaphandle olungabuy ebonakalayo kwawo sohlobo oluthile ubudlelwane, kunye nokufikelela kade kumanqanaba asezantsi enkqubo oluneqela elinegunya.
Enye kunjalo xa usebenzisa imodeli data ezinobume, esibonakala yi isakhiwo elula kakhulu. Oku kuphunyezwa njenge tafile onamacala amabini ezixhasa ubuhlobo ethile. Indlela zonxulumelwano kwithuba elide wahlala ngaphandle ingqalelo eyiyo, njengoko wabuza kwezibonelelo computer kakhulu. Nangona kunjalo, nokufika imeko computer yakho itshintshile. Kunye nemodeli enjalo ukuba aququzelele data phantse indawo nezinye iinkqubo. UMdali incarnation yale mbono banika ihlabathi sisixhobo umsebenzi ngempumelelo kunye nobudlelwane.
Le Uthungelwano data imodeli naliphi na ilungu unokuba uxhulumaniso ngqo kunye nenye into. Kukho ezinye ezifanayo kunye nenkqubo oluneqela elinegunya, kodwa umahluko amanga neqiniso ukuba nokunyamezela yoqhagamashelo amaninzi inxalenye zibekwe kwinqanaba eliphezulu. Oku ulandelele ngoko ngokucacileyo ulwalathiso amakhonkco, ngoko ke kufuneka zicaciswe xa inkcazo ledatha. Ububi le modeli iquka ukungabikho ukhuseleko ulwazi, kodwa ingxaki kusonjululwa kwixesha langoku esebenzayo kakhulu.
Naziphi na iinkcukacha wadala ngokusekelwe kwezi modeli. Umahluko phakathi kwabo ngcembe shwaka ngenxa kusungulo into ebomini information technology. imodeli ngamnye uneempawu ezithile, ezivumela ukufezekisa kangangoko ngezicelo ezithile. Ngokungafaniyo zolwazi zonxulumelwano kwezinye oontanga oko banako ukutshintsha isakhiwo emva entry data. Noko ke, database enkulu ekubeni nesakhiwo invariable kunye intsebenziswano rhoqo kunye izicelo ibe nemveliso kakhulu ngokubhekiselele isantya ukufikelela.
