Itafile Ngaba kukho nawuphi na iDatha

Yonke idatha eyenziweyo ilingana neTable. Ukusetyenziswa okulula ukuyisebenzisa kusetyenziswa imoto yedatha ngokukhawuleza ukuba iinkqubo zedatha ezivela kwimithombo eyahlukileyo engaqhelekanga. Akusekho isidingo sokuxininisa malunga nesofthiwe yokubona idatha ekusebenziseni ngombono wakho, kuba iThebula yenza konke.

Ukutshitshisa, ukuBoniswa kwamaTekisi

Mhlawumbi inqaku elikhethiweyo elikhethiweyo I-Tableau inabalandeli abangaphezu kwamandla abo ukudala ukubonakaliswa kwedatha emangalisayo. Dlulela phambili, iThebhile inikezela ukubonakaliswa kwedatha yokubambisana nesebenzisi yesoftware yolwazi.

Ukufanisana kwiiplatifti ezininzi

Ithebhile ishintshe icandelo lophando loshishino ngokwenza ukuqonda kuvuleke ngokukhawuleza kunoma ubani-nokuba ingafowuni yefowuni, inkqubo yewebhu, i-iPad okanye ifowuni.

Itheyibhile yiNkokeli yezoNkampani

Ithebula lizuze iindumiso ezingenakubalwa kuzo zonke i-shishini lolwazi lwezoshishino kwaye lijika ngokukhawuleza kumgangatho wokujonga kwedatha esemgangathweni.

Ithebula liye laphumelela kwiingcali zoshishino zengqondo kwiGartner njengoko isigaba seBI sesigqibo.
