Ithebula: Ithuluzi Elibalulekile Ledeshibhodi Esebenzayo
Emhlabeni wokubukwa kwedatha, i-Tableau izimise njengomholi ongenambangi. Ikhono layo lokuguqula idatha engahluziwe ibe ukuboniswa okusebenzisanayo nokuqondakalayo alinakuqhathaniswa. Ukuqeqeshwa kokuthi “Dala ideshibhodi nge-Tableau” ku-OpenClassrooms kukuqondisa ezinyathelweni ezibalulekile ukuze ube yingcweti yaleli thuluzi elinamandla.
Enye yezinzuzo ezinkulu ze-Tableau kulula ukuyisebenzisa. Ngisho nangaphandle kokuhlela kwangaphambilini noma isipiliyoni sokuklama, abasebenzisi bangakha amadeshibhodi ahlaba umxhwele. Lokhu kwenziwa ngenxa ye-interface enembile ekuvumela ukuthi uhudule futhi ulahle izinto ukuze wakhe ukubonwa.
Kodwa ungalenzi iphutha, naphezu kokubonakala kwayo kulula, i-Tableau inamandla kakhulu. Ingakwazi ukuxhuma emithonjeni eminingi yedatha, kusukela kumaspredishithi e-Excel alula kuye kusizindalwazi esiyinkimbinkimbi. Uma usuxhunyiwe, idatha ingashintshwa, ihlungwe futhi iguqulwe ukuze ihlangabezane nezidingo ezithile.
Okunye amandla e-Tableau yikhono layo lokwenza amadeshibhodi asebenzisane. Abasebenzisi bangachofoza, basondeza noma bahlunge idatha ngokuqondile ukusuka kudeshibhodi, banikeze ulwazi olunzulu ngomsebenzisi.
Ngamafuphi, i-Tableau ayilona nje ithuluzi lokubonisa idatha, iyinkundla ephelele yokuhlaziya idatha. Inhlanganisela yayo eyingqayizivele yobulula namandla ikwenza kube ukukhetha okuncanyelwayo kubahlaziyi bedatha namabhizinisi emhlabeni jikelele.
Ukudlula ukubuka ngeso okulula: Ukuhlanganiswa nezilimi zokuhlela
Amandla e-Tableau awekho nje emandleni ayo okudala ukubukeka okumangalisayo. Amandla ayo eqiniso ayavezwa uma ehlanganiswa nezilimi zohlelo lwewebhu. Lokhu kusebenzisana kwenza kube nokwenzeka ukwakha amadeshibhodi omuntu siqu, ajwayelane nezidingo ezithile zephrojekthi ngayinye.
Ukuhlanganiswa kwe-Tableau nezilimi ezifana ne-HTML, i-JavaScript (okuhlanganisa nelabhulali ye-D3.js), kanye nohlaka lwe-Python Flask luvula umhlaba wamathuba. Cabanga nje ukwazi ukuhlanganisa amandla okubona e-Tableau nokuguquguquka nokwenza ngendlela oyifisayo okunikezwa yilezi zilimi. Lokhu kukuvumela ukuthi udale amadeshibhodi adlulela ngalé kokumelelwa okulula kwesithombe sedatha.
Isibonelo, ngeFlask, i-Python micro-framework, kungenzeka ukudala iseva yewebhu ephakela ideshibhodi yakho ngesikhathi sangempela. Idatha ingabuyekezwa khona manjalo, inikeze umbono osesikhathini samanje wesimo.
Ngaphezu kwalokho, ukusetshenziswa kwe-JavaScript, ikakhulukazi i-D3.js, kwenza kube nokwenzeka ukwengeza izithombe ezinyakazayo, ukusebenzisana kanye nemiphumela ebonakalayo eyenza ideshibhodi ihehe nakakhulu kumsebenzisi.
Ngokuhlanganisa lobu buchwepheshe, amadeshibhodi aba izinhlelo zokusebenza zewebhu zangempela, ahlinzeka ngolwazi olunzulu ngomsebenzisi olucebile. Awaselona nje amathuluzi okubona ngeso lengqondo, kodwa aba amathuluzi anamandla okwenza izinqumo, ukuhlaziya kanye namasu.
Ngamafuphi, inhlanganisela ye-Tableau nezilimi zokuhlela zewebhu ithatha ukubonwa kwedatha ezingeni elilandelayo, iguqula amadeshibhodi abe amathuluzi ashukumisayo nasebenzisanayo wamabhizinisi esimanje.
