Ukufaka Amanani Amaningi Ku-Sql
U-Alyssa, umpetha wamarobhothi kanye nochwepheshe be-AI onothando lokuqamba izinto ezintsha, uhlola umhlaba wokuphathwa kwedathabhesi, ehlola ubunkimbinkimbi bokufaka amanani amaningi ku-SQL. Ngesipiliyoni seminyaka engaphezu kwe-11 ku-AI namarobhothi, u-Alyssa uthuthukise ukuqonda okujulile kwamandla alobu buchwepheshe.
Njengonjiniyela oholayo e-Lockheed Martin, u-Alyssa wengamela ukuthuthukiswa kwama-drones anamandla e-AI, ephusha imingcele yalokho okungenzeka ensimini. Ubuchwepheshe bakhe budlulela ngalé komkhakha wezobuchwepheshe, njengoba ephinde abe ngumbhali oshisekayo futhi oshisekela ukusungula izinto ezintsha ezisezingeni eliphezulu. Lapho engasebenzi kumaphrojekthi we-AI, u-Alyssa angatholakala eqhudelana emiqhudelwaneni yomshayeli wendiza ye-drone noma ehalalisela i-Chicago Bears yakhe ayithandayo.
Ukufaka amanani amaningi ku-SQL kungaba umsebenzi onzima, ikakhulukazi kulabo abasha ekuphathweni kwesizindalwazi. Kodwa-ke, ngendlela efanele, kungaba isiguquli segeyimu kuzinhlelo zokusebenza eziqhutshwa idatha. Kulesi sihloko, sizohlola umqondo wokufaka amanani amaningi ku-SQL futhi sinikeze imininingwane engasebenza yokuthi ungayithola kanjani.
Kuyini Ukufaka Amanani Amaningi Ku-Sql nethi Kungani Kubalulekile?
Ukufaka amanani amaningi ku-SQL kusho inqubo yokwengeza imigqa eminingi yedatha kuthebula lesizindalwazi ekusebenzeni okukodwa. Lokhu kungaba usizo ikakhulukazi ezimeni lapho udinga ukungenisa amadathasethi amakhulu noma ugcwalise ithebula ngenani elibalulekile ledatha.
Enye yezinzuzo eziyinhloko zokufaka amanani amaningi ku-SQL ukusebenza kahle okulethayo ekuphathweni kwedatha. Ngokunciphisa inani lezitatimende zokufaka ngazinye, ungathuthukisa kakhulu ukusebenza kwesizindalwazi sakho sokusebenza. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho idatha ivuselelwa njalo noma ifakwa.
Isibonelo, zicabange usebenza kuphrojekthi ye-Deere, umkhiqizi wezinto zezolimo ohamba phambili, futhi udinga ukufaka imininingwane egciniwe enezinzwa ezivela kumishini ehlukahlukene yasepulazini. Ukufaka amanani amaningi ku-SQL kuzokuvumela ukuthi ungenise kahle futhi ugcine le datha, okwenza kube lula ukuhlaziya nokwenza izinqumo ezinolwazi.
Nokho, ukufaka amanani amaningi ku-SQL nakho kuza nesethi yayo yezinselelo. Enye yezingozi eziyinhloko ukungahambisani kwedatha, lapho idatha engalungile noma eyimpinda ishuthekwa kusizindalwazi. Ukuze unciphise lokhu, kubalulekile ukusebenzisa ukuqinisekiswa kwedatha okuqinile nezindlela zokuphatha amaphutha.
Isimo Somhlaba Wangempela: Ukuguqula Ukufaka Amanani Amaningi Ku-Sql Yempumelelo
Ake sicabangele isimo sokucatshangelwa lapho usebenza khona kuphrojekthi yokuthuthukisa uhlelo lokuqapha ezolimo olunamandla e-AI. Uhlelo ludinga ukuthi uqoqe futhi ugcine idatha evela kuzinzwa ezihlukahlukene, okuhlanganisa izinga lokushisa, umswakama, namazinga omswakama enhlabathini.
Usebenzisa indlela evamile, uzodinga ukubhala izitatimende zokufaka ngazinye zokufundwa kwenzwa ngayinye, okungadla isikhathi futhi kujwayele ukuba namaphutha. Nokho, ngokusebenzisa i-syntax ethi FAKA ... VALUES, ungafaka imigqa eminingi yedatha ekusebenzeni okukodwa, okwenza ngcono kakhulu ukusebenza kahle kwedatha yakho yokusebenza.
Nasi isibonelo sokuthi ungasebenzisa kanjani i-syntax ethi INSERT IN … VALUES ukuze ufake imigqa eminingi yedatha:
- FAKA KU-sensor_readings izinga lokushisa, umswakama, inhlabathi_umswakama AMAZINGA 23.5, 60.2, 40.1, 24.1, 65, 42, 25.6, 68, 43;
Le syntax ikuvumela ukuthi ufake imigqa eminingi yedatha ekusebenzeni okukodwa, okwenza kube lula ukuphatha amasethi wedatha amakhulu futhi uthuthukise ukusebenza kwedatha yakho yokusebenza.
I-Actionable Insights: Ungayithola Kanjani Ukufaka Amanani Amaningi Ku-Sql
Ngakho-ke, ungafinyelela kanjani ukufaka amanani amaningi ku-SQL? Nansi eminye imininingwane engasebenza ukuze uqalise:
Sebenzisa i-syntax ethi FAKA ... AMAZINGA: Le syntax ikuvumela ukuthi ufake imigqa eminingi yedatha ekusebenzeni okukodwa, okwenza kube lula ukuphatha amadathasethi amakhulu.
Sebenzisa ukuqinisekiswa kwedatha okuqinile nezindlela zokuphatha amaphutha: Ukuze unciphise ubungozi bokungahambisani kwedatha, kubalulekile ukusebenzisa ukuqinisekiswa kwedatha okuqinile nezindlela zokuphatha amaphutha.
3. Sebenzisa imibuzo enepharamitha: Imibuzo enepharamitha ingasiza ukuthuthukisa ukuvikeleka nokusebenza kwesizindalwazi sakho sedatha ngokunciphisa ubungozi bokuhlaselwa komjovo we-SQL.
4. Thuthukisa i-schema sesizindalwazi sakho: I-schema yesizindalwazi esiklanywe kahle singasiza ukuthuthukisa ukusebenza kwesizindalwazi sakho ngokunciphisa inani lokujoyina kanye nemibuzo edingekayo.
Ngokulandela le mininingwane engenzeka, ungakwazi ukufaka amanani amaningi ngempumelelo ku-SQL futhi uthuthukise ukusebenza kwedatha yakho egciniwe.

U-Alyssa ungumakadebona wamarobhothi futhi uchwepheshe we-AI onothando lokuqamba izinto ezintsha. Ngesipiliyoni seminyaka engaphezu kwe-11 ku-AI namarobhothi, u-Alyssa uthuthukise ukuqonda okujulile kwamandla alobu buchwepheshe. Uphinde abe ngumbhali oshisekayo futhi oshisekela ukusungula izinto ezintsha, futhi uyakujabulela ukuncintisana emiqhudelwaneni yomshayeli wendiza eyi-drone futhi ajabulele amthandayo iChicago Bears.
U-Alyssa uneziqu zeComputer Science azithola eNyuvesi yaseChicago futhi unomlando ofakazelwe wokuletha izixazululo ezintsha emkhakheni we-AI namarobhothi. Uzibophezele ekwabelaneni ngobuchule nolwazi lwakhe nabanye, futhi uhlale efuna izindlela ezintsha zokuphusha imingcele yalokho okungenzeka.
Umusho wokuzihlangula: Ulwazi olunikezwe kulesi sihloko ngelezinjongo zokufundisa kuphela futhi akufanele luthathwe njengeseluleko sochwepheshe. Kuhlale kunconywa ukuthi ubonane nochwepheshe abaqeqeshiwe ngaphambi kokusebenzisa noma ibuphi ubuchwepheshe obusha noma isisombululo.
