Ziva simba re databases neSQL
Munyika yanhasi yedhijitari, data iri pamwoyo pesarudzo dzese. Kunyangwe kuongorora maitiro evashandisi, kugadzirisa mashandiro ebhizinesi, kana kufanotaura mafambiro emangwana, kugona kubvunza nekunzwisisa dhatabhesi kwakakosha. Apa ndipo panopinda SQL, kana Structured Query Mutauro.
Chidzidzo OpenClassrooms "Bvunza Dhatabhesi neSQL" inopa kudzika kwakadzika munyika yeSQL. Kubva pakutanga, vadzidzi vanounzwa kune yehukama modhi, zvichivabvumira kuti vanzwisise kuti data rakagadzirwa sei uye rakabatana. Iine hwaro hwakasimba uhu, kosi yacho inozotungamira vashandisi kuburikidza nekuvaka kweiyo nyore SQL mibvunzo, ichivapa maturusi ekuburitsa ruzivo rwakakwana kubva mudhatabhesi.
Asi kudzidza hakugumiri ipapo. Iyo kosi inoenderera mberi nekuongorora epamberi SQL maficha, akadai sekuunganidza data, kusefa, uye kuronga. Aya hunyanzvi hwepamusoro anobvumira vashandisi kushandisa uye kuongorora data nenzira dzakaomarara, kuvhura musuwo wekuongorora kwakadzama uye mamwe manzwisisiro.
Muchidimbu, kune chero munhu anoda kugona hunyanzvi hwekutarisira data, kosi iyi inofanirwa-kuve nayo. Inopa kudzidziswa kwakazara, kubva kune ekutanga pfungwa kusvika kune epamusoro matekiniki, kuve nechokwadi chekuti vadzidzi vakanyatsoshongedzerwa kugona nyika yakapfuma uye yakaoma yedatabase.
Kusimuka kweSQL mune Yanhasi Tekinoroji Landscape
Munyika iyo data iri mambo, kuziva nzira yekuibata nayo kwave chinhu chikuru. SQL, acronym yeStructured Query Mutauro, ndiwo mutauro wesarudzo wekudyidzana nemadatabase. Asi nei kufarira kwakadaro kweSQL mune yazvino tekinoroji mamiriro?
Kutanga, SQL ndeyepasi rose. Mazhinji dhatabhesi manejimendi masisitimu, angave echinyakare kana emazuva ano, anotsigira SQL. Uhu hwepasirese hunoreva kuti hunyanzvi hwakawanikwa mundima iyi hunochinjika, zvisinei neiyo tekinoroji.
Chechipiri, simba reSQL riri mukureruka kwayo. Nemirairo mishoma yakanyatsosarudzwa, munhu anogona kubvisa, kugadzirisa, kudzima kana kuwedzera data. Uku kuchinjika kunobvumira makambani kugadzirisa nekukurumidza, kuongorora data ravo munguva chaiyo uye kuita sarudzo dzine ruzivo.
Pamusoro pezvo, munguva iyo hunhu hwakakosha, SQL inobatsira kuendesa zviitiko zvinoenderana. Kunyangwe kurumbidza chigadzirwa kumutengi kana kutarisira mafambiro emusika, SQL chishandiso chesarudzo chekuongorora data uye kugadzira ruzivo rwakakodzera.
Chekupedzisira, OpenClassrooms SQL kudzidziswa haingodzidzisi iwe dzidziso. Inonyudza iwe muzviitiko zvinoshanda, ichikugadzirira kutarisana nematambudziko chaiwo enyika yehunyanzvi.
Saka, kugona SQL kunoreva kuve nehunyanzvi hwakakosha, pasipoti yechokwadi kune nyika yedata.
Zvimise iwe pamberi peiyo data revolution
Nguva yedhijitari yakagadzira kuputika kwedata. Kudzvanya kwese, kupindirana kwese, kutengeserana kwese kunosiya dhijitari tsoka. Asi iyi data, yakakura sezvairi, ingori ruzha pasina maturusi akakodzera ekududzira. Apa ndipo apo mastery yeSQL inova chinhu chakakosha.
Fungidzira gungwa remashoko. Pasina kambasi yakarurama, kufamba munyanza iyi kunogona kuita sekwakaoma. SQL ndiyo kambasi, inoshandura makomo e data yakasvibira kuita zvinogoneka kuona. Iyo inounza nhamba kuhupenyu, inoburitsa mapatani, maitiro uye nzwisiso ingadai yakavanzwa.
Asi kunze kweiyo nyore kudhirowa kweruzivo, SQL irevheti yekushandura. Mabhizinesi anoitora anogona kunatsiridza marongero avo, kukwidziridza mashandiro avo uye kuunza yakasarudzika yevatengi zviitiko. Mumusika wakazara, kugona uku kwekuvandudza uchishandisa data ndiyo mukana mukuru wemakwikwi.
Kune nyanzvi, kugona SQL kunopfuura hunyanzvi hwekuita. Mutauro wepasirese unovhura magonhi muzvikamu zvakasiyana, kubva kumari kuenda kuhutano, kuburikidza nekushambadzira uye e-commerce. Ivimbiso yemukana, kukura nekuzivikanwa.
Mukupedzisa, mune isingaregi data ballet yezana ramakore rechiXNUMX, SQL ndiye kondakita, achiwiriranisa mafambiro ese, chinyorwa chega chega, kugadzira symphony yeruzivo. Kudzidziswa muSQL kunoreva kusarudza kuve mutambi mune iyi symphony, uye kwete muoni ari nyore.
Unyanzvi hwako hwakapfava hune basa, asi ndizvo zvakaita hupenyu hwako pachako. Wana kuenzana nechinyorwa ichi pa Chiitiko cheGoogle.
