Zitholele amandla emininingwane nge-SQL
Ezweni lanamuhla ledijithali, idatha isenhliziyweni cishe yazo zonke izinqumo. Ukuthi uhlaziya ukuziphatha kwabasebenzisi, ukuthuthukisa ukusebenza kwebhizinisi, noma ukubikezela amathrendi azayo, ikhono lokubuza nokuqonda imininingwane yolwazi libalulekile. Kulapho i-SQL, noma Ulimi Oluhlelekile Lombuzo, ingena khona.
Isifundo “Buza isizindalwazi nge-SQL” ku-OpenClassrooms inikeza ukungena okujulile emhlabeni we-SQL. Kusukela ekuqaleni, abafundi bethulwa ekumodeleni okuhlobene, okubavumela ukuthi baqonde ukuthi idatha yakheka kanjani futhi ixhumeke kanjani. Ngalesi sisekelo esiqinile, isifundo sibe sesiqondisa abasebenzisi ekwakhiweni kwemibuzo elula ye-SQL, ibanikeze amathuluzi okukhipha ulwazi olunembile kusizindalwazi.
Kodwa ukufunda akugcini lapho. Isifundo siqhubekela phambili ngokuhlola izici ezithuthukile ze-SQL, njengokuhlanganisa idatha, ukuhlunga, nokuhlela. Lawa makhono athuthukisiwe avumela abasebenzisi ukuthi basebenzise futhi bahlaziye idatha ngezindlela eziyinkimbinkimbi, evula umnyango wokuhlaziya okujulile kanye nemininingwane eminingi.
Sekukonke, kunoma ubani ofisa ukuba yingcweti kwezokuphatha idatha, lesi sifundo siyimfuneko. Inikeza ukuqeqeshwa okuphelele, kusukela emiqondweni eyisisekelo kuya kumasu athuthukile, okuqinisekisa ukuthi abafundi bahlonyiselwe kahle ukwazi umhlaba ocebile noyinkimbinkimbi wolwazi.
Ukunyuka kwe-SQL ku-Today Technology Landscape
Ezweni lapho idatha iyinkosi, ukwazi ukuthi iphathwa kanjani sekuyimpahla enkulu. I-SQL, isifinyezo se-Structured Query Language, iwulimi olukhethwayo lokusebenzelana nezizindalwazi. Kodwa kungani uthando olungaka lwe-SQL endaweni yamanje yezobuchwepheshe?
Okokuqala, i-SQL iyindawo yonke. Iningi lezinhlelo zokuphatha isizindalwazi, noma ngabe zendabuko noma zesimanje, zisekela i-SQL. Lokhu kutholakala emhlabeni wonke kusho ukuthi amakhono atholwe kulo mkhakha ayadluliswa, kungakhathaliseki ukuthi ibuphi ubuchwepheshe obukhona.
Okwesibili, amandla e-SQL alele ekululameni kwayo. Ngemiyalo embalwa ekhethwe kahle, umuntu angakhipha, alungise, asuse noma engeze idatha. Lokhu kuvumelana nezimo kuvumela izinkampani ukuthi zizivumelanise nezimo ngokushesha, zihlaziye idatha yazo ngesikhathi sangempela futhi zenze izinqumo ezinolwazi.
Futhi, enkathini lapho ukwenza kube ngokwakho kubalulekile, i-SQL isiza ukuletha ukuzizwisa okuhambisanayo. Ukuthi uncoma umkhiqizo kuklayenti noma amathrendi alindelwe emakethe, i-SQL iyithuluzi lokuzikhethela lokuhlaziya idatha kanye nokukhiqiza imininingwane efanele.
Ekugcineni, ukuqeqeshwa kwe-OpenClassrooms SQL akufundisi nje ithiyori. Ikugxilisa ezimweni ezingokoqobo, ikulungiselela ukubhekana nezinselele zangempela zomhlaba wochwepheshe.
Ngakho-ke, ukwenza kahle i-SQL kusho ukuba nekhono elibalulekile, ipasipoti yeqiniso emhlabeni wedatha.
Zibeke phambili ekuguquleleni idatha
Iminyaka yedijithali ilethe ukuqhuma kwedatha. Njalo ngokuchofoza, konke ukusebenzelana, konke okwenziwayo kushiya izigxivizo zeminwe. Kodwa le datha, njengoba injalo, iwumsindo nje ngaphandle kwamathuluzi afanele wokuyisusa. Yilapho ubungoti ku-SQL buba yimpahla eyigugu.
Cabanga ngolwandle lolwazi. Ngaphandle kwekhampasi efanele, ukuzulazula kulolu lwandle kungase kubonakale kungaphezu kwamandla. I-SQL yileyo khampasi, eguqula izintaba zedatha eluhlaza ibe yimininingwane esebenzayo. Iletha izinombolo ekuphileni, amaphethini avezayo, izitayela kanye nemibono ebingafihlwa.
Kepha ngale kokukhishwa okulula kolwazi, i-SQL iyisigaxa soguquko. Izinkampani ezilamukelayo zingathuthukisa amasu azo, zithuthukise ukusebenza kwazo futhi zilethe umuzwa okhethekile wamakhasimende. Emakethe egcwele, leli khono lokusungula izinto ezintsha usebenzisa idatha liyinzuzo enkulu yokuncintisana.
Kochwepheshe, ukwenza kahle i-SQL kungaphezu kwekhono lobuchwepheshe. Iwulimi lomhlaba wonke oluvula iminyango emikhakheni eyahlukene, kusukela kwezezimali kuye kwezempilo, ngokumaketha kanye ne-e-commerce. Kuyisithembiso samathuba, ukukhula nokuqashelwa.
Sengiphetha, ku-ballet engapheli yedatha yekhulu lama-XNUMX, i-SQL ingumqhubi, evumelanisa konke ukunyakaza, yonke inothi, ukudala i-symphony yolwazi. Ukuqeqeshwa ku-SQL kusho ukukhetha ukuba umlingisi kule symphony, hhayi nje isibukeli.
Amakhono akho athambile abalulekile, kodwa kunjalo nempilo yakho yomuntu siqu. Thola ibhalansi ngalesi sihloko Umsebenzi we-Google.
