Imininingwane

Imininingwane yolwazi ngasikhathi sinye yezingxenye ezisetshenziswa kakhulu futhi ezingasetshenziswanga kakhulu. Kuyiqiniso ukuthi zingamathuluzi adingekayo ochwepheshe bezobuchwepheshe bolwazi. KephaEndabeni yabasebenzisi abasebenza ngekhompyutha yabo, kungenzeka ukuthi bakhulume ngokusetshenziswa kabi. Ngaphandle kokuthi, bakuhlelo lokusebenza olufaka phakathi, njengalapho upheqa futhi ubeka amazwana kule bhulogi.

Kuyiqiniso ukuthi ukusebenzisa ispredishithi kunembile futhi kunemibhalo eminingi etholakalayo. IMicrosoft uqobo ishicilele incwadi eyodwa ku-Access futhi lokho ukulungiselela ukuhlolwa kwesitifiketi. Mayelana ne-LibreOffice Base, imibhalo etholakalayo (ngesiNgisi) ifinyelela enguqulweni engu-6.4.

Kodwa, ijika lokufunda elikhulu linxeshezelwa yizinzuzo ngoba zilungele ukusebenza ngemininingwane engeyona eyamanani.

Imininingwane Yikuphi?

Imininingwane i iqoqo lemininingwane ehlelwe ngendlela ethile futhi eligcinwe ngekhompyuthafuthi. Ngohlelo olubizwa ngokuthi umphathi wedatha, luphethe ukwenza lula ukungezwa, ukuguqulwa nokuqedwa okufanayo. Ezinye izinhlobo zolwazi zisebenzisa ulimi oluthile lohlelo oluvumela imibuzo.

Ukuhlukaniswa

Ngokuya ngendawo

  • Imininingwane emaphakathi: Itholakala, igcinwe futhi inakekelwe endaweni eyodwa. Lokhu akusho ukuthi umsebenzisi kufanele abe sendaweni efanayo ukuze afinyelele kuyo.
  • Imininingwane ehanjisiwe: Lokhu empeleni yolwazi oluhlukile ezindaweni ezihlukile zomzimbaBahlanganiswe yimenenja ebenza basebenze sengathi babodwa.

Ngokwendlela yokwakha ubudlelwano phakathi kwedatha

  • Ubudlelwano: Kulolu hlobo lwe-database lezi zihlelwe ngendlela yemigqa namakholomu.
  • Okuqondiswe entweni: Lapha idatha igcinwa ngendlela yezinto. Lezi zinto zigcinwa ku-database ngokuzinikeza izimfanelo nezindlela ezichaza ukuthi zenzeni ngedatha.
  • Eqondiswe kwigrafu: Isebenzisa i- Umbono we-Graphic Schema ukugcina, ukwenza imephu, nokubuza ubudlelwane phakathi kwedatha.
  • I-NoSQL: Ivumela idatha engakhiwe ukuthi igcinweZihleleke kancane.
  • Eyenzelwe amadokhumenti: Yisihlokwana sangaphambilini. Esikhundleni sokugcina idatha ngemigqa namakholomu isebenzisa imibhalo ukugcina nokukhipha idatha. Le mibhalo ihlela idatha isebenzisa amazinga afana ne-JSON noma i-XML.

Ngokuya nge-orientation

  • OLTP: Ziyizizinda zolwazi okuqondiswe ekusetshenzisweni kokuthengiselanafuthi kubandakanya ukufaka idatha, ukuguqula nokususa imisebenzi.
  • I-OLAP: Lezi yolwazi zikhona okuqondiswe ekuhlaziyweni kwedatha ukuvumela iziphetho ukuthi zithathwe.

Ezinye izinhlobo

  • Ukuzimela: Kususelwa emafini futhi sebenzisa ukufundwa komshini ukwenza ngokuzenzakalela umsebenzi wedatha,  ukuphepha, izipele, izibuyekezo neminye imisebenzi yokuphatha ejwayelekile eyenziwe ngumlawuli kulwazi lwendabuko.
  • Indawo yokugcina imininingwane: Idatha egxile emkhakheni wezinkampani leyo uhlanganisa futhi ahlanze imininingwane emithonjeni eyehlukene ukuyicubungula nokuyihlaziya dUkusuka emibonweni eyahlukene ngejubane elikhulu.

Kuvulwe imininingwane yolwazi ephathelene

Akunangqondo kule bhulogi ukucacisa ukuthi yini umehluko phakathi kwalokhu okubili. Uma kuyathakazelisa ukubona ukuthi ukusetshenziswa kwakho kokubili kusatshalaliswa kanjani. Ngokwezibalo zamanje kakhulu, kwezingu-5 ezisetshenziswe kakhulu, ezintathu zingumthombo ovulekile. Izindaba ezimnandi ukuthi ezimbili zomthombo ovulekile; IPostgreSQL neMongoDB babone ukukhula okumangazayo; 3% no-44,02% ngokulandelana.

Ukushaywa okukhulu kuthathwe yiseva yeMicrosoft SQL (ephathelene) nokuwa kwama-70,81% ngenkathi umkhiqizo ohola phambili, i-Oracle iqoqa ukwehla kwama-28,08%. I-MySQL, edume kakhulu ngezixazululo zomthombo ovulekile, ayizange ihambe kahle kakhulu futhi. nge-24,28% kubhodi yamaphuzu.

Noma kunjalo, lesi sibalo kufanele uyithathe ngezimbadamba. Imithombo yokubala isikhundla senjini ngayinye yedatha yile:

  • Inani lemiphumela kuzinjini zokusesha.
  • Imvamisa yokusesha ngokuya ngamathrendi weGoogle
  • Inani lemibuzo kumaphosta wemibuzo nezobuchwepheshe.
  • Inani lokunikezwa kwemisebenzi.
  • Imvamisa yokushiwo kumaphrofayli ochwepheshe.
  • Inani lokushiwo kumanethiwekhi omphakathi.

  1. Unomthwalo wemfanelo ngedatha: AB Internet Networks 2008 SL
  2. Inhloso yedatha: Lawula Ugaxekile, ukuphathwa kwamazwana.
  3. Ukusemthethweni: Imvume yakho
  4. Ukuxhumana kwemininingwane: Imininingwane ngeke idluliselwe kubantu besithathu ngaphandle kwesibopho esisemthethweni.
  5. Isitoreji sedatha: Idatabase ebanjwe yi-Occentus Networks (EU)
  6. Amalungelo: Nganoma yisiphi isikhathi ungakhawulela, uthole futhi ususe imininingwane yakho.

    Sawubona futhi okuhle
    Kuhle kakhulu lokho okushicilelayo nokwabelana ngakho, esinakho futhi okufanele sikufunde nsuku zonke.
    Ngiyavumelana nawe ukuthi ezikhathini eziningi imininingwane yolwazi ayisetshenziswa kahle.
    Kuyithuluzi elinamandla ku-Access namuhla kukhona ubuchwepheshe obuhlukahlukene futhi abacabangi ukuthi konke kuyadingeka.
    Kwenziwa ama-webs e-Dynamic, kusetshenziswa izilimi zokuhlela ukudala nokufaka imininingwane, kanye nokuyikhipha.
    Kepha isizinda sokuFinyelela asicatshangwa njengohlelo, ukusetshenziswa kwaso kweminye imikhakha cishe akunalutho.
    Ngiyethemba konke kuzothuthuka ngoba kuningi okusamele sikwenze ngolwazi.
