Ngitshele izigaba ezahlukene zomjikelezo wokuphila kwedatha.
1. Izinkomo Ukufakwa kwedatha: Kulesi sigaba, idatha evela kubakhiqizi iyadliwa futhi iqoqwe ukuze isetshenziswe kamuva. 2. Izingelosi Ukucutshungulwa Kwemininingwane: Uma imininingwane isiqoqiwe futhi iqoqiwe, ikakhulukazi ngefomethi eluhlaza, idlula ezinyathelweni ezahlukahlukene zokucubungula. Ingenye yemithwalo yemfanelo eyinhloko yemibhobho yedatha. Lesi sigaba singahlukaniswa sibe izigaba ezincane. 3. Izindaba Ezinhle Ukugcinwa Kwemininingwane: Yonke imininingwane eqoqwe futhi yacutshungulwa igcinwa ngamafomethi ahlukahlukene. Ngokuya ngezidingo ezithile, kungase kusetshenziswe ithuluzi elilodwa noma amaningi noma amapharadigm. 4. Izidakamizwa Ukuhlaziywa kwedatha noma ukubonwa: Kulesi sigaba, idatha ecutshunguliwe ihlaziywa ukuze kutholakale imininingwane enenjongo futhi iningi layo likhona ngendlela ethile ebonakalayo.
