Kuyini database ne lapho kungasetshenziswa

Qonda lokho database, akunzima. Sihlala njalo ebhekene izinhlobo zalo, hhayi ngisho nokwazi. Ngokwesibonelo, kunoma iyiphi umkhakha, kunoma yisiphi isikhungo, lapho abantu emsebenzini, imishini isetshenziswa, kukhona database lapho ulwazi aqoshiwe eyayiphathelene esigcwele amayunithi, okungukuthi, Ukwakheka abasebenzi, izisebenzi, hardware esetshenziswa (yokusungula). umtapo ifayela Isikhwama ikhadi kubuye kube isibonelo esihle database.

Ngakho, liyini base idatha? It babuthana ehlelekile ngendlela ekhethekile ulwazi ngendaba ethile ngaphakathi endaweni isihloko. Futhi uma emashumini ambalwa eminyaka edlule, ulwazi olufanele kulotshwe futhi agcinwe ephepheni, manje zonke izinto ezithakazelisayo singenelwe ikhompyutha futhi agcinwe inguqulo computer.

ngezigaba

On okuqukethwe database of impahla ihlukaniswe okuyiqiniso futhi documentary. Iyiqiniso aqukethe ulwazi kafushane mayelana into echazwe. Ulwazi lunikezwa ngendlela ethile nesakhiwo. Ngokwesibonelo, uma sikhuluma database umtapo ke kulo mayelana incwadi ngayinye iqukethe ulwazi lwempilo ezifana ngonyaka nendawo ncwadi, umbhali, isihloko, njll Okuqukethwe umsebenzi, izincwadi umbhalo, database ezinjalo ngeke aqukethe. Human Resources database yayo uzobuyisa ukwaziswa okumayelana abasebenzi - Igama lakho eliphelele, usuku kanye nendawo lokuzalwa, izikole grade, ubuthishela, endaweni yomsebenzi, njll

Idokhumentari semininingwane ingaqukatha omningi ulwazi raznotipovoy: lombhalo, ihluzo, amafayela soxhumanoningi. Ngakho, Discography i sijwayeleke - isampula database documentary. Kusukela ke ungakwazi ukuthola mayelana albhamu ezikhishwe umculi, abalobi zezingoma, ukulalela izingoma, amavidyo kliphu athathwe nabo.

Ngosizo lwezobuchwepheshe banamuhla imingcele ephakathi yolwazi okuyiqiniso futhi documentary Akasekho abukhali. Manje wena kalula ukuxhuma Imininingwane komunye uhlobo database kwenye.

isitoreji Imininingwane - yilokho database, kanye nokufinyelela lenqwaba wabo sibonga i-Internet isiyindlela umsebenzi kakhulu, silula.

Ngokwe-hlobo lokucubungula nokudilivela Imininingwane egciniwe zihlukaniswe zingubudlelwane nakunethiwekhi.

Uyini semininingwane zingubudlelwane ukuthi kungenziwa alungise uma ulwazi udaba ifomu amathebula. Lamathebuli kuxhumene. Ngakho, yokusungula amathoyizi esitolo isitokwe kungenziwa imelelwa itafula, lapho izinhlobo amathoyizi (amabhere, izinja, izindlovu, njll) izofakwa ohlwini e amakholomu, inombolo zohlobo ngalunye oluphilayo zakwazi (amabhere - 20 izinja - 35, njll) , intengo hit value grand ingqikithi zonke izimpahla.

A database zingubudlelwane Kulula kakhulu ukusebenzisa futhi ajwayelekile isikhathi eside. Isikole idayari kusukela isimiso sesikole okuqoshiwe wesikole, ukuhlolwa nokubona - kuyinto database tabular. Uhlelo izitimela noma amabhasi esiteshini - ubuye database zingubudlelwane.

A database zingubudlelwane siqukethe lemigqa namakholomu. Ithebula irowu ubizwa nangokuthi irekhodi, futhi ikholomu - ensimini. Irekhodi liqukethe ulwazi mayelana imodeli into uhlelo, okuyinto itafula.

Okuningi eziyinkimbinkimbi imodeli database database inethiwekhi. Eqinisweni, i-database inthanethi - lena Inthanethi uqobo, World Wide Web, i-Global Network. Ngenxa hyperlink, izigidi imibhalo kuxhumene. Ngakho akha elilodwa ukusatshalaliswa senethiwekhi yeselula. Futhi cishe noma yimuphi umsebenzisi Inthanethi Ungaxhuma futhi uthole ulwazi olulungile.

Ngaphezu kwalokho, uma amakhompyutha ambalwa uxhumeke master olulodwa futhi kungaba, sibonga kuye, ngesikhathi esifanayo ukusebenza kunethiwekhi, akha inethiwekhi yendawo noma egciniwe yendawo.

Yilokho database kusho ukuthini futhi kusebenza kanjani.
