Yintoni database kwaye zingasetyenziswa apho

Qonda into ledatha, akukho nzima. Sijongene rhoqo iintlobo zawo, nkqu bengazi nto. Umzekelo, kulo naliphi na icandelo, kulo naliphi na iziko, apho abantu, kusetyenziswa izixhobo, kukho uvimba apho kweenkcukacha kwi-bexesha elizeleyo iiyunithi, ie, ukwakhiwa abasebenzi, abasebenzi, iintsimbi esetyenziswa (inventory). ilayibrari ikhadi fund wefayile kwakhona ngumzekelo omhle ledatha.

Ngoko ke, yintoni isiseko data? Ngayo ndawonye kunye nemibutho ngendlela ekhethekileyo ulwazi ngesihloko esithile ngaphakathi kwisifundo. Ukuba eminyaka embalwa eyadlulayo, ingcaciso eyimfuneko irekhodwa yaye igcinwe ephepheni, ngoku zonke izinto umdla ungeneyo ekhompyutheni ize igcinwe uguqulelo computer.

ngezigaba

Kwisiqulatho iziko ledatha ngezixhobo yahlulwe ezineengongoma amaxwebhu. Eziyinyaniso eziqulathe ulwazi emfutshane malunga into echazwe. Ulwazi inikwa ngendlela ethile kunye nendlela. Ngokomzekelo, xa sithetha database yamathala eencwadi, ngoko kuye malunga kwincwadi nganye iqulethe ulwazi lombhalo ezifana unyaka kunye nendawo wopapasho, umbhali, isihloko, njl Umxholo yomsebenzi, iincwadi itekisi, uvimba ezinjalo abayi kubudla ziqulathe. Human Resources database wayo uya kugcina ulwazi lobuqu malunga nabasebenzi - Igama elipheleleyo, umhla nendawo wokuzalwa, izikolo libakala, umsebenzi, indawo emsebenzini, njl

Amaxwebhu database singaqulatha isixa esikhulu ulwazi raznotipovoy: lo mbhalo, imizobo, iifayile yemultimedia. Ngoko ke, lo Discography kukho othile - isampula obubhaliweyo ledatha. Kuwo uyakwazi ukufumana phandle malunga albhamu wakhululwa imvumi, nababhali iingoma, uphulaphule iingoma, ukubukela umboniso esithathwe kunye nabo.

Ngenxa yeteknoloji ekhoyo imida phakathi iinkcukacha ezinobunyaniso amaxwebhu azisekho elibukhali. Ngoku ngokulula ukudibanisa ulwazi ukusuka kwenye uhlobo database kwenye.

yokugcina ulwazi - yiloo nto-database, kunye nokufikelela kwinani elikhulu kubo enkosi kwi Internet iye yaba umsebenzi kakhulu, ilula kakhulu.

Ngokutsho uhlobo processing kunye nokuhanjiswa kolwazi database zahlulwe zibe zonxulumelwano kunye nothungelwano.

Yintoni i- database zonxulumelwano ukuba unako zinokulungiswa ngayo ukuba ulwazi umba kulo ngohlobo nezingqengqelo. Ezi theyibhile zidibene. Ngenxa yoko, i-inventri zokudlala kwi ivenkile yempahla angamelwa njenge itafile, apho iintlobo zokudlala (amabhere, izinja, iindlovu, njl) ziya kudweliswa kwiikholam, inani iintlobo ngamnye (amabhere - 20 izinja - 35, njalo njalo) , ixabiso ibetheke ixabiso grand total zonke iimpahla.

A ledatha zonxulumelwano Kulula kakhulu ukuba ukusebenzisa neziqhelekileyo ixesha elide. idayari School evela kwishedyuli yesikolo ushicilelo wasekhaya, uhlolo kunye nemigqaliselo - kuyinto database tabular. Ishedyuli koololiwe okanye neebhasi kwisikhululo - naye database zonxulumelwano.

A database zonxulumelwano ibandakanya lwemiqolo nemihlathi. umqolo Table ukwabizwa ngokuba ingxelo, ze kwikholam - endle. Ingxelo iqulathe ulwazi malunga imodeli inkqubo into, nto leyo itafile.

model database esimbaxa ke senethiwekhi. Enyanisweni, i-database intanethi - oku ke Internet ngokwayo, i-World Wide Web, i-Global Network. Enkosi hyperlink, izigidi amaxwebhu ziqhagamshelwe. Ngoko ke ukwakha uvimba omnye distribution network. Kwaye phantse nawuphi na umsebenzisi Internet ukudibanisa kuyo kwaye ufumane ulwazi ekunene.

Ukongeza, ukuba iikhompyutha eziliqela eqhagamshelwe inkosi abangatshatanga unako, Bulelani kuye, ngexesha elifanayo ukusebenza kwi-network, zakha inethwekhi yendawo okanye kuvimba wasekuhlaleni.

Yiloo nto uvimba nokuba isebenza njani.
