Fumana amandla oovimba beenkcukacha ngeSQL
Kwihlabathi lanamhlanje ledijithali, idatha isembindini waso sonke isigqibo. Nokuba kuhlalutya iindlela zokuziphatha zabasebenzisi, ukwandisa ukusebenza kweshishini, okanye ukuqikelela iintsingiselo zexesha elizayo, ukukwazi ukubuza kunye nokuqonda oovimba beenkcukacha kubalulekile. Apha kulapho i-SQL, okanye uLwimi lokuBuza oluLungisiweyo, lungena khona.
Isifundo "Buza isiseko sedatha ngeSQL" kwi-OpenClassrooms inikeza ukuntywila nzulu kwihlabathi le-SQL. Kwasekuqaleni, abafundi baziswa kumzekelo wonxulumano, okubavumela ukuba baqonde indlela idatha eyakhiwe ngayo kwaye iqhagamshelene ngayo. Ngesi siseko esiqinileyo, ikhosi ke ikhokela abasebenzisi ngokwakhiwa kwemibuzo ye-SQL elula, ibanika izixhobo zokukhupha ulwazi oluchanekileyo kwiinkcukacha.
Kodwa ukufunda akupheleli apho. Ikhosi iqhubela phambili ngokuphonononga iimpawu eziphambili zeSQL, ezifana nokuhlanganiswa kwedatha, ukuhluza, kunye nokucwangcisa. Ezi zakhono ziphezulu zivumela abasebenzisi ukuba basebenzise kwaye bahlalutye idatha ngeendlela ezinobunkunkqele, bevula umnyango kuhlalutyo olunzulu kunye nokuqonda okungakumbi.
Lilonke, kuye nabani na onqwenela ukugqwesa ubugcisa bolawulo lwedatha, le khosi iyimfuneko. Inika uqeqesho olubanzi, ukusuka kwiikhonsepthi ezisisiseko ukuya kubuchule obuphambili, iqinisekisa ukuba abafundi baxhotyiswe kakuhle ukuze bakwazi ukugqwesa ihlabathi elityebileyo nelintsokothileyo logcino-lwazi.
Ukunyuka kwe-SQL kuMmandla weTekhnoloji yanamhlanje
Ehlabathini apho idatha iyinkosi, ukwazi indlela yokuyilawula kuye kwaba yinto ebalulekileyo. I-SQL, i-acronym ye-Structured Query Language, lulwimi olukhethwayo lokusebenzisana novimba weenkcukacha. Kodwa kutheni uthando olunjalo lwe-SQL kumhlaba wangoku wetekhnoloji?
Okokuqala, i-SQL yindawo yonke. Uninzi lweenkqubo zolawulo lwesiseko sedatha, nokuba zemveli okanye zangoku, zixhasa iSQL. Le ndalo yonke ithetha ukuba izakhono ezifunyenweyo kulo mmandla ziyakwazi ukudluliselwa, kungakhathaliseki ukuba iteknoloji ephantsi.
Okwesibini, amandla e-SQL alele kubulula bayo. Ngemiyalelo embalwa ekhethwe kakuhle, umntu unokukhupha, ukuguqula, ukucima okanye ukongeza idatha. Oku kuguquguquka kuvumela iinkampani ukuba zilungelelanise ngokukhawuleza, zihlalutye idatha yazo ngexesha langempela kwaye zenze izigqibo ezinolwazi.
Kwaye, kwixesha apho ukwenziwa komntu kungundoqo, iSQL inceda ukuhambisa amava alungiselelweyo. Ingaba uncoma imveliso kumthengi okanye ulindeleke kwiindlela zemarike, i-SQL sisixhobo sokuzikhethela ukuhlalutya idatha kunye nokuvelisa ukuqonda okufanelekileyo.
Okokugqibela, uqeqesho lwe-OpenClassrooms SQL alufundisi nje ithiyori. Ikuntywilisela kwiimeko ezisebenzayo, ikulungiselela ukuba ujongane nemiceli mngeni yokwenyani yehlabathi lobuchwephesha.
Ke, ukubamba iSQL kuthetha ukuba nesakhono esixabisekileyo, ipaspoti yokwenyani kwihlabathi ledatha.
Zibeke phambili kwi-data revolution
Ixesha ledijithali lizise ukuqhuma kwedatha. Unqakrazo ngalunye, yonke intsebenziswano, yonke intengiselwano ishiya umnwe. Kodwa le datha, inamandla njengoko injalo, yingxolo nje ngaphandle kwezixhobo ezifanelekileyo zokuyicima. Kulapho ubuchule kwiSQL buba yi-asethi exabisekileyo.
Yiba nomfanekiso-ngqondweni wolwazi oluninzi. Ngaphandle kwekhampasi efanelekileyo, ukuhamba kolu lwandle kunokubonakala kunzima. I-SQL yikhampasi, ukuguqula iintaba zedatha ekrwada zibe yimibono esebenzayo. Izisa amanani ebomini, iipateni ezityhilayo, iintsingiselo kunye nokuqonda ngekube kufihlwa.
Kodwa ngaphaya kokutsalwa ngokulula kolwazi, i-SQL sisileva soguqulo. Iinkampani eziyamkelayo zinokucokisa izicwangciso zazo, zandise ukusebenza kwazo kwaye zinike namava akhethekileyo kubathengi. Kwimarike egcweleyo, obu buchule bokwenza izinto ezintsha kusetyenziswa idatha luncedo olukhulu lokhuphiswano.
Kuba iingcali, mastering SQL ngaphezu isakhono zobugcisa. Lulwimi lwehlabathi jikelele oluvula iingcango kumacandelo ahlukeneyo, ukusuka kwezezimali ukuya kwezempilo, ngokuthengisa kunye norhwebo lwe-e-commerce. Sisithembiso samathuba, ukukhula kunye nokuqondwa.
Ukuqukumbela, kwi-ballet engapheliyo yedatha yekhulu lama-XNUMX, i-SQL ngumqhubi, ukulungelelanisa yonke intshukumo, yonke inqaku, ukudala i-symphony yolwazi. Ukuqeqeshwa kwi-SQL kuthetha ukukhetha ukuba ngumdlali kule symphony, kwaye kungekhona nje umbukeli.
Izakhono zakho ezithambileyo zibalulekile, kodwa kunjalo nobomi bakho bomntu. Fumana ibhalansi kunye neli nqaku Umsebenzi kaGoogle.
