Yenza ukuxhuma kuspredishithi ku-database
I-database inikeza indlela ehlelekile yokugcina, yokuphatha nokuthola ulwazi. Benza kanjalo ngokusebenzisa ukusetshenziswa kwamatafula. Uma ujwayele amaspredishithi afana neMicrosoft Excel , cishe usujwayele ukugcina idatha ngesimo sefomu. Akuyona okuningi yokwehlisa ukukhipha amaspredishithi kuma-yolwazi.
Amadatha namaSpredishithi
Ulwazi oluhle kakhulu kunezipredishithi zokugcina idatha eminingi, noma kunjalo, nokuphatha lelo datha ngezindlela ezihlukahlukene. Uhlangana namandla okulondoloza ulwazi ngaso sonke isikhathi ekuphileni kwakho kwansuku zonke.
Isibonelo, uma ungena ku-akhawunti yakho yebhange yase-inthanethi, ibhange lakho liqinisekisa kuqala ukungena kwakho usebenzisa igama lakho lomsebenzisi nephasiwedi bese ubonisa ibhalansi yakho ye-akhawunti nanoma yikuphi ukuthengiselana. Kuyinto yedatha esebenza ngemuva kwezigcawu ezihlola igama lakho lomsebenzisi nephasiwedi, bese ikunikeza ukufinyelela ku-akhawunti yakho. I-database ihlunga ukuthengiswa kwakho ukuwabonisa ngosuku noma uhlobo, njengoba ucela.
Nazi ezinye zezenzo ongayenza kwi-database okungaba nzima, uma kungenakwenzeka, ukwenza ku-spreadsheet:
- Thola wonke amarekhodi afana nemigomo ethile
- Buyekeza amarekhodi ngobuningi
- Amarekhodi e-cross-reference etafuleni ezahlukene
- Yenza izibalo ezihlanganisiwe eziyinkimbinkimbi
Ake sicabangele ezinye zezingqinamba eziyisisekelo ngemuva kwedatha.
Izinto Zedatha
I-database yenziwe ngamatafula amaningi. Njengamatafula e-Excel, amatafula egciniwe egciniwe anamakholomu nemigqa. Ikholomu ngayinye ihambelana nesici , futhi umugqa ngamunye uhambisana irekhodi elilodwa. Ithebula ngalinye kufanele libe negama eliyingqayizivele ku-database.
Isibonelo, cabanga ngetafula lemininingwane elinegama namanani ocingweni. Cishe uzosetha amakholomu okuthiwa "FirstName," "LastName" ne "TelephoneNumber." Khona-ke uzovele uqale ukungeza imigqa ngaphansi kwalakholomu aqukethe idatha. Etafuleni lwazi lokuxhumana lwebhizinisi elinabasebenzi abangu-50, sizovuleka ngetafula equkethe imigqa engu-50.
Isici esibalulekile setafula ukuthi ngamunye kumele abe nekholomu eyinhloko yokhiye ukuze umugqa ngamunye (noma irekhodi) inenkambu ehlukile ukuyikhomba.
Idatha ku-database ibuye ivikeleke nakakhulu lokho okubizwa ngokuthi izingqinamba . Izingqinamba ziphoqelela imithetho kwimininingwane ukuqinisekisa ubuqotho bayo bonke. Isibonelo, isibopho esiyingqayizivele siqinisekisa ukuthi ukhiye oyinhloko awukwazi ukuphindiwe. Isivinini sokuhlola silawula uhlobo lwedatha ongayifaka-isibonelo, igama legama lingavuma umbhalo ocacile, kodwa insimu yenombolo yokuphepha yomphakathi kufanele ifake isethi ethize yezinombolo. Kunezinye izinhlobo eziningana zezinkinga, futhi.
Esinye sezici ezinamandla kunazo zonke ze-database yikhono lokudala ubuhlobo phakathi kwamatafula usebenzisa okhiye bangaphandle. Isibonelo, ungase ube netafula lamakhasimende kanye netafula le-oda. Ikhasimende ngalinye lingakwazi ukuxhunyaniswa ne-oda etafuleni lakho le-oda.Ithebula le-oda, futhi, lingase lixhunywe kuthebula lemikhiqizo. Loluhlobo lwemiklamo luhlanganisa idatha yokuxhumana futhi yenza lula ukuklama kwedatha yakho ukuze ukwazi ukuhlela idatha ngesigaba, kunokuba uzame ukubeka yonke idatha kuthebula elilodwa, noma amatafula ambalwa nje.
I-Database Management System (i-DBMS)
I-database ivele ibambe idatha kuphela. Ukusebenzisa kwangempela idatha, udinga uhlelo lokuphathwa kwedatha (DBMS). I-DBMS iyi-database ngokwalo, kanye nayo yonke isofthiwe kanye nokusebenza ukuthola idatha kusuka database, noma ukufaka idatha. I-DBMS idala imibiko, iqinisa imithetho yemininingwane kanye nezinkinga, futhi igcina uhlelo lwemininingwane yedatha. Ngaphandle kwe-DBMS, i-database ingumqoqo wezinkinobho nama-byte onencazelo encane.
