Iyini indawo yokugcina idatha futhi isetshenziswa kanjani?
Context:E-computing, indawo yokugcina idatha (i-DW noma i-DWH), eyaziwa nangokuthi indawo yokugcina idatha yebhizinisi (i-EDW), uhlelo olusetshenziselwa ukubika nokuhlaziya idatha futhi lubhekwa njengengxenye eyinhloko yobuhlakani bebhizinisi. Ama-DW ayindawo yokugcina imininingwane ehlanganisiwe evela emthonjeni owodwa noma eminingi ehlukene. Zigcina idatha yamanje neyomlando endaweni eyodwa esetshenziselwa ukudala imibiko yokuhlaziya yabasebenzi kuyo yonke ibhizinisi. Lokhu kunenzuzo ezinkampanini njengoba kuzenza zikwazi ukubuza futhi zithole ukuqonda kwedatha yazo futhi zenze izinqumo.  Idatha egcinwe endaweni yokugcina impahla ilayishwa kusuka ezinhlelweni zokusebenza (njengokumaketha noma ukuthengisa). Imininingwane ingadlula endaweni yokugcina idatha yokusebenza futhi ingadinga ukuhlanzwa kwedatha ukuze kwenziwe imisebenzi eyengeziwe ukuqinisekisa ikhwalithi yedatha ngaphambi kokuba isetshenziswe ku-DW yokubika.  Ukukhipha, ukuguqula, ukulayisha (i-ETL) nokukhipha, ukulayisha, ukuguqula (i-ELT) yizindlela ezimbili eziyinhloko ezisetshenziselwa ukwakha uhlelo lokugcina idatha.
Izindawo zokugcina idatha ziyizinhlelo ezigcina ulwazi lwamanje nolwedlule endaweni eyodwa futhi zenzelwe ukwenza imibiko nokuhlaziywa kwedatha. Kunezinhlobo ezimbili eziyinhloko zokucubungula idatha endaweni yokugcina idatha: Khipha, uguqule, ulayishe (i-ETL) bese ukhipha ukulayisha nokuguqula (i-ELT)
