Kuqheleke zolwazi

Ngokwamaqela idatha efanayo kwi table kungenziwa ngeendlela ezahlukeneyo. Iimpawu nolwalamano kufuneka amaqela ngaqela ngokungqinelana kumgaqo ezinobume, oko kukuthi, kufuneka ukunciphisa ngokupheleleyo phindwa data, ngokunjalo lula inkqubo unyango lwabo kulandele lohlaziyo. Enye yeengxaki eziphambili kunye nokuyila database wenza ngokupheliswa komsebenzi, kwaye kuyafikelelwa yi ukuzinza.

database ukuzinza imele izithintelo izixhobo ezisesikweni ukudala iitheyibhile evumela ukuphelisa phindwa, kunye ulwazi software igcinwe uzinzo efunekayo, ukunciphisa iindleko zabasebenzi ezinxulumene kunye nokugcina kunye nokugcinwa ledatha. ukusebenza ukuzinza sikuko ukwandiswa iitafile zesiseko sedata original zibe lula. Kwinqanaba ngalinye yale nkqubo ngokuyimfuneko itafile enikwe ngendlela eqhelekileyo. isigaba ngasinye luphawulwa kuqheleke ezithile izithintelo, kufuneka athobele zonke iitafile. Ngenxa yoko, ukususwa yenziwa ulwazi itheyibhile non-ezingundoqo, nto leyo ezingasafunekiyo.

Kuqheleke edatha isekelwe ingqikelelo yokuxhomekeka esebenza phakathi iimpawu. Kucingwa ukuba Imfanelo lixhomekeke kwelinye icala, ukuba ixesha ngalinye ixabiso ethile lesiphumo yesibini ingqamana akukho ngaphezu kwesinye ixabiso lokuqala.

Kuqheleke zolwazi - igama jikelele, nangona kunjalo, oku kwahlulwa ibe ngeendlela eziliqela oluqhelekileyo, nto leyo eza kuxoxwa kamva.

A into data kucingwa efanelekileyo kwifom yokuqala eqhelekileyo xa ixabiso lemfanelo ngalinye kwayo. Ukuba phawu othile ixabiso nempinda, mayingabi sakhululwa ingqalelo into besive kwifom yokuqala eqhelekileyo. Kubonakala ukuba ungenza i kusekho naziphi na kwiqumrhu na into data.

A into idatha ithathwa kwakucingwa ukuba ifomu yesibini oluqhelekileyo xa sele ekwimo yokuqala oluqhelekileyo, kodwa ngamnye iimpawu zayo, hayi owakhiwa ngendlela isakhono, elizimeleyo ngokupheleleyo ngokwemigqaliselo ezisebenzayo ngalinye okunamandla izitshixo.

A into data kucingwa ukuba lilungu kwendlela yesithathu eqhelekileyo, ukuba sele ingohlobo yesibini oluqhelekileyo, kodwa akuzange kube izixhomekeki Isixando izinto ezingezizo ezibalulekileyo izitshixo. Phantsi ukuxhomekeka Isixando lidla kuqondwa unxulumano ocacileyo phakathi emasimini.

Ukuzinza database ubeka umphuhlisi njongo ephambili ukuba zazise bonke ubuhlobo kwendlela yesithathu eqhelekileyo. Kuphela ngale ndlela kwixesha elizayo kuya kuba lula ukwenza i inkqubo yolwazi esebenzayo.

Kuqheleke zolwazi: imithetho esisiseko

Kufuneka kuqulunqa uluhlu lwemithetho ekufuneka ilandelwe emsebenzini ukuzinza. Olokuqala ngaphandle amaqela abaphinda. Kuyimfuneko ukwenza itheyibhile eyahlukileyo ukugcina iseti ngamnye lweempawu ezinxulumene, nto leyo idala isitshixo esahlukileyo. Okulandelayo, qiniseka ukuba ukuphelisa data ezingasafunekiyo. Kwiimeko apho ubudlelwane lesiphumo waphawula kuphela inxalenye iqhosha, ngoko ke kufuneka abekwe etafileni eyahlukileyo. Umthetho wesithathu inyanzelekile ngaphandle kwimiqolo loo nto ixhomekeke isitshixo. Iimpawu kufuneka ibekwe kwetafise ekwanti, ukuba awunayo yifuna kwi isitshixo. Qiniseka ukuba ikheswa ubudlelwane ezizimeleyo ezininzi. Kule meko sithetha ngento kungabonwa uxhulumaniso eziphathekayo kunxulumano phakathi ezininzi. Okokugqibela, kubalulekile ukuba ikheswa ubudlelwane ezininzi ezinxulumene semantically. Kule ukuzinza ledatha igqityiwe, kulandelwa yinkqubo yophuhliso.
