Database

Yini i-Database

Un database iqoqo idatha ihlelwe ngendlela ehlelekile ukuze kube lula ukufinyelela, ukuphatha kanye nokuhlaziya. Kucabange njengenqolobane enkulu yolwazi, lapho yonke into igcinwa kahle futhi itholakala kalula.

Zicabange unencwadi yocingo enezinombolo zocingo zabangane bakho. Irubrikhi ilula database: iqukethe idatha (amagama nezinombolo zocingo) zihlelwe ngendlela ehlelekile (ngokwesibonelo, ngokulandelana kwezinhlamvu).

I database asetshenziswa ezimweni ezehlukene, kusukela kwezebhizinisi kuye kwezesayensi, ukugcinwa kanye nokuphatha ulwazi lwemvelo ehlukene:

  • Idatha yomuntu siqu ye amakhasimende: igama, isibongo, ikheli, ucingo, i-imeyili.
  • Imisebenzi yezezimali: idethi, inani, uhlobo lokwenziwe, ohlomulayo.
  • Imikhiqizo eku-inventory: ikhodi yomkhiqizo, incazelo, inani, inani elitholakalayo.
  • Izindatshana zebhulogi: isihloko, umbhali, usuku lokushicilela, umbhalo.
  • Okuthunyelwe mayelana social media: umbhalo, izithombe, amavidiyo, usuku lokushicilela, umbhali.

Kunezinhlobo ezahlukene ze database, ngayinye enezici ezithile kanye nezinzuzo:

  • Database ubudlelwano: babambe ngekhanda i idatha ematafuleni anobudlelwano obuchaziwe phakathi kwabo. Ziwuhlobo olusabalele kakhulu futhi zinikeza ukuguquguquka okuphezulu nokuqina. Izibonelo: I-MySQL, i-PostgreSQL, i-Oracle.
  • I-NoSQL: yakhelwe ukuphatha idatha engahlelekile noma engahlelekile. Zifanele ikakhulukazi izinhlelo zokusebenza zewebhu neselula. Izibonelo: I-MongoDB, i-Cassandra, i-Redis.
  • Database enkumbulweni: babambe ngekhanda i idatha kumemori eguquguqukayo yokufinyelela okusheshayo kombani. Asetshenziselwa izinhlelo zokusebenza ezidinga izikhathi ezimfushane zokuphendula. Izibonelo: Redis, Memcached.

I database zingafakwa futhi ziphathwe kuseva yazo noma zingasetshenziswa njengesevisi ku ifu. Izinsizakalo ze database in ifu banikeza izinzuzo eziningana, ezifana nokuqina, ukuguquguquka nokuvikeleka.

Kungani usebenzise a database?

I database nikeza izinzuzo ezimbalwa:

  • Inhlangano: i idatha zigcinwa ngendlela ehlelekile nehlelekile, kube lula ucwaningo kanye nokufinyelela olwazini.
  • Ukusebenza kahle: i database ikuvumela ukuthi uphathe amavolumu amakhulu idatha ngendlela ephumelelayo.
  • Ukuhlaziya: i idatha ingahlaziywa ukuze kutholwe ulwazi oluwusizo lwebhizinisi.
  • Ukuphepha: i database ukunikeza izici eziningana ukuvikela yakho idatha kusukela ekufinyeleleni okungagunyaziwe.

Isiphetho:

I database ayithuluzi eliyisisekelo lokugcina, ukuphatha kanye nokuhlaziya idatha. Ukukhetha uhlobo database futhi isevisi yokubamba efanelekile kakhulu incike ezintweni eziningana, njengohlobo lwe idatha ukulondoloza, umthamo we idatha, ukusebenza okudingekayo kanye nezindleko.

Umlando wolwazi
Umlando wemininingwane yolwazi: uhambo ngokuhamba kwesikhathi

Umsuka we database kusukela ekuqaleni kwekhompyutha, lapho i idatha zazigcinwe emakhadini apuntshiwe kanye nakumateyipu kazibuthe. Ukuphatha lolu lwazi kwakuyinqubo ekhandlayo futhi edinga amakhono athile.

60s:

  • Igama lazalwadatabase” ukukhombisa iqoqo le idatha kwabiwe abasebenzisi abaningi.
