Uma usebenza ngamanani akhulayo edatha, lesi sifundo se-Tableau 2019 esakho. U-Andre Meyer, umdali nombhali wezincwadi zobuhlakani bebhizinisi, uzokusiza ukuthi udale amadeshibhodi asebenzayo naguqukayo nezethulo. Ukuhlanganiswa kwedatha kusetshenziswa izinsiza ze-Excel kuzombozwa. Sizophinde sihlanganise nokudala amashadi ahlukahlukene, okuhlanganisa amathebula namagridi. Okulandelayo, uzofunda ukuthi ungawakha kanjani amadeshibhodi asebenzisanayo usebenzisa amashadi. Ekupheleni kwesifundo, uzokwazi ukukhohlisa idatha futhi udale imibiko.
Ithebula liyini?
I-Tableau, umkhiqizo wenkampani ezinze e-Seattle, yasungulwa ngo-2003. Isofthiwe yabo ngokushesha yaba elinye lamathuluzi angcono kakhulu okuhlaziya idatha emakethe. I-Tableau isethi ephelele yamathuluzi ashintshashintsha njalo. Kuyi-software engasetshenziswa abantu abaningi abahlukene. Eqinisweni, kulula ukuyisebenzisa kangangokuthi ungakha ishadi elilula ngemizuzwana. Ngeshwa, kuthatha iminyaka yesipiliyoni ukusebenzisa ngokugcwele leli thuluzi nezici zalo ezithuthukile.
Kungani ukhetha i-Tableau kunezinye izixazululo ze-BI ezifana ne-MyReport, i-Qlik Sense noma i-Power BI?
- ukwenziwa lula kokuqoqwa nokuhlaziywa kwedatha
Idatha ingaqoqwa, ihlanzwe futhi ihlaziywe ngendlela enembile, ngaphandle kokudinga ulwazi lokuhlela. Lokhu kuvumela abahlaziyi bedatha nabasebenzisi bebhizinisi ukuthi bahlaziye amasethi edatha amakhulu nayinkimbinkimbi.
- amadeshibhodi asebenzisanayo futhi anembile.
I-Tableau ayibizwa ngokuthi i-Tableau mahhala: Amadeshibhodi e-Tableau aziwa ngokusebenziseka kalula kwawo, ukuguquguquka okubonakalayo, kanye namandla. Kuyindlela enhle yokwelula ukusetshenziswa kwamadeshibhodi enhlanganweni yakho.
- idatha kuzindaba ezizuzisa kakhudlwana kusetshenziswa i-Dataviz kanye Nezindaba Zedatha.
I-Tableau inikezela ngeqoqo lamathuluzi e-Dataviz (amashadi, amamephu, izibalo, njll.) akuvumela ukuthi utshele abasebenzisi izindaba ezingcono mayelana nedatha yakho. Umgomo wokuxoxa indaba uwukwenza idatha iqondakale ngokuyethula ngendlela yendaba. Le ndaba kufanele ikhulume nezithameli ezithile futhi iqondakale. Lokhu kusiza ukusatshalaliswa kolwazi ngaphakathi kwenhlangano.
