Kuyini Ukuhlaziywa Kwemininingwane?
Ukwakhiwa kwephrofayili yedatha kungenye yezimiso zokuphathwa kwedatha. Ukwenza amaphrofayili kwedatha kuwumsebenzi wokuthola amaphethini kudatha. Ukwakhiwa kwephrofayili yedatha kwenziwa amaqembu anokufinyelela kwamanye amasethi wedatha ezimweni zokusetshenziswa ezahlukahlukene njengokuthola amaphethini wedatha, ukuhlaziywa kwezinga eliphakeme, ukuphatha okuhlukile kwedatha kwe-ETL njll. Ukwakhiwa kwephrofayili yedatha kuyingxenye yokuqala yomjikelezo wokuphila wekhwalithi yedatha ngaphakathi kwendlela yokuphathwa kwedatha. Ukuqopha idatha kumaqoqo wedatha kungaphendula imibuzo elula efana nokuthi mangaki ama-nulls kudathasethi, yiziphi izindlela ezahlukahlukene zamadethi kudathasethi njll. Ukuqopha idatha kuvame ukwenziwa kusethi engaphansi kwedatha. Amathuluzi anemikhawulo enanini lomugqa kusethi yedatha angakwazi ukuyikhomba. La mathuluzi angakha futhi ukubonwa kwemiphumela yokuprofetha ukuze kuqondwe kalula amaphethini.
