Uyewo achibatsirwa wavo zvinokwanisika yokuchengetera umboo pamusoro zvinhu, takaberekwa tine zvakafanana ehupfumi.

Kuti vagadzire Database idzva, unofanira kutanga kuziva chii mhando uye mashoko ezvirevo zvinoshandiswa mairi (zvimwe haukwanisi kuwana chaizvo chaidiwa, nokuti ruzivo huri Databases anofanira muronga).

Marudzi anotevera zvino kushandiswa Database: network, tabular uye hierarchical. Chokwadi, munyika dzakawanda zvinhu nokuda kusarudza zvatinoda uye chaizvo mashoko nako basa rinoitwa.

The inonyanya kufarirwa mhando - tabular Database. Zvinosanganisira nyore pasi zvinhu saizvozvo. mhando, mune mamwe mazwi, zvinhu, takaberekwa tine dzakafanana ehupfumi. Izvi mhando Mutungamiri nekuti unokubvumira kupedza pamusoro rokunyora Databases ndoda nguva. Databases izvi mhando kunogona akagadzira kushandisa chete Excel, umo huru hwindo muchitokisi anogona kupiwa kune mhando dzose spreadsheet data, zvinoti rugwaro, Masvomhu uye nhamba.

Uyezve, tabular Database inogona achimiririrwa nyore maviri-dimensional tafura. Mumwe musara tafura iyi wazara successively anokoshesa ane chinhu uye pfuma tsika vanoonekwa saizvozvo yoga pembiru.

Pachavo mbiru petafura yakadaro dzinonzi minda. minda All anozivikanwa nemazita akasiyana uye ane mashoko kuratidza aida parameter ukoshi.

Panyaya iyi, ngationei kuyeuka kamwe zvakare kuti kana isu patsanura mhando Databases pamusoro kudekara pakusika uye rokuzadza Database tafura kuchaita kutora nzvimbo yokutanga nokuti pfuma iyi.

Pakunyora of chinhu - kutumidza munhu akarongwa tafura Database. Ita izvi zvinyorwa Software vanokamurwa kuminda wandei tichibatsirwa tafura yembiru, saka vose zvinyorwa - rinoisa runodiwa tsika zviri musango.

Kana taida funga zvimwe mhando Databases, asi ikozvino aizofanira kutsanangura zvikuru chaiwo mazwi. Nokuti zvakafanana, kutsanangura tafura chawo, uye nhatu vasisina. Chokwadi kuti zvinyorwa uye paminda chinhu chakadai, Tatoona, uye parizvino tsanangudzo kiyi munda.

Chinokosha munda anotaurwa somumwe paminda tafura, mutengo anopiwa umo zvakananga inechirevo chero yakanyorwa tafura mumasero.

munda Key kazhinji chine date mhando mhando "yemabhuku". Zvishoma kacho, zvinotevera mashoko mhando anoshandiswa: "nhamba accession", "chigadzirwa bumbiro", etc ...

The Mhando yeminda pachavo anowanzoshandurwa pakutsvaga date ravakange ane. The Mhando chikuru "pakaunda", "chinyorwa", "nhamba", "Musi / nguva", "mari", "musoro", "URL".

Mumwe mhando rinoshandiswa, tinotevedzera zvinodiwa mugumisiro. Hazvina kuchenjera kubvumirana, kushandisa mhando "URL" apo zvakakodzera chisarudzo "Date / Time". Kana ukaita chinhu kuzvitsinhanisa yakadaro, ipapo zvose basa achaenda, sezvo vachiti, kururama, pamwe nemhaka yokuti mashoko anogona dzaona nepasipo.

Ndokusaka tichifanira kutsaura pakati munhu marudzi Databases uye munda mhando anomiririrwa mazviri.
