Ubuchwepheshe bedatha buhluke kanjani kwisayensi yedatha?
Ubunjiniyela bedatha buqala ngaphambi kwesayensi yedatha kumjikelezo wokuphila kwedatha. Imininingwane ingakhiqizwa emithonjeni ehlukahlukene futhi le mininingwane eluhlaza ingaba eyakhiwe, eyakhiwe kancane noma engahlelekile. Ukuze le datha ibe nengqondo, idatha kumelwe idliwe futhi iguqulwe. Yilapho ubunjiniyela bemininingwane buba khona. Ubunjiniyela bedatha buhlanganisa inqubo yokukhipha idatha eluhlaza, ukufaka idatha ohlelweni olufana nedatha echibini, ukuguqula idatha ngezidingo zebhizinisi futhi ekugcineni uyilayishe etafuleni. Lokhu ngokuvamile kwaziwa ngokuthi i-ELT (Extract-Load-Transform). I-ETL (Extract-Transform-Load) nayo ingenzeka lapho ukuguqulwa kwenzeka ngaphambi kwesigaba sokulayisha. I-Data Science and Analytics iyisinyathelo esilandelayo emjikelezweni wokuphila kwedatha. Lapho idatha edingekayo ngezidingo ezithile zebhizinisi isitholakala, ososayensi bedatha basebenzisa le datha ukuqhuba amamodeli wokufunda ngomshini ukuthola imodeli enembile kakhulu. Le mininingwane itholakala kososayensi bemininingwane ngendlela yamatafula. Abahlaziyi bemininingwane basebenzisa le mininingwane ukwenza ukuhlaziywa okuhlola nokwakha amadeshibhodi. Ngokuyisisekelo, umjikelezo wokuphila kwedatha uzobukeka kanje: Idatha eluhlaza evela emithonjeni ehlukene -> Idatha Engineering -> Data Science and Analytics
