Desktop kunye neeNkqubo zoLondolozo lweeNcedisi zeSeva
I-Oracle, iSQL Server, i-Microsoft Access, i-MySQL, i-DB2 okanye i-PostgreSQL? Kukho iintlobo ezahlukeneyo zemveliso yedatha kwimarike namhlanje, ukwenza ukhetho lweqonga leziseko zophuhliso lwenkqubo yakho.
Chaza iimfuno zakho
Iinkqubo zolawulo lweDatabase (okanye i-DBMS) zingahlula kwiindidi ezimbini: yolwazi lwedesktop kunye nolwazi lweeva. Ngokuqhelekileyo, ii-desktop yolwazi zijoliswe kwiinkqubo zabasebenzisi abangabodwa kwaye zihlala kwiikhomputha zomntu eziqhelekileyo (ngoko ke idesktop yekota).
Iinkcukacha zolwazi zeseva ziqulethe iindlela zokuqinisekisa ukuthembeka kunye nokuhambelana kwedatha kwaye zijoliswe kwizicelo ezininzi zomsebenzisi. Ezi zolwazi zenzelwe ukuba ziqhube kumaseva aphezulu kwaye zithwale ixabiso elifanayo eliphezulu.
Kubalulekile ukwenza uhlalutyo lweemfuno phambi kokuba ungene ngaphakathi kwaye uzinikele kwisisombululo sedatha. Uza kufumana ukuba idesksiphu yedeskithophu ifanelekile kwiimfuno zoshishino lakho xa uceba ukuqala ukuthenga isisombululo esisezantsi esisezantsi. Unokufumanisa iimfuno ezifihliweyo ezifuna ukuba kuthunyelwe i-database ekhuselekile, esekelwe kwiseva.
Inkqubo yohlalutyo lweemfuno iya kuba yinkcazo kwintlangano yakho kodwa, ubuncinane, kufuneka uphendule le mibuzo ilandelayo:
- Ngubani oza kusebenzisa i-database kwaye yimiphi imisebenzi eya kuyenza?
- Ixesha liza kuguqulwa lwedatha? Ngubani oya kwenza oku kulungiswa?
- Ngubani oza kunika inkxaso ye-IT kwisiseko sedatha?
- Yiyiphi i-hardware ekhoyo? Ngaba kukho uhlahlo lwabiwo-mali lokuthenga i-hardware eyongeziweyo?
- Ngubani oza kuba noxanduva lokugcina idatha?
- Ngaba ukufikelela kwedatha kuya kunikwa kwi-Intanethi? Ukuba kunjalo, yiyiphi inqanaba lokufikelela ekufuneka lixhaswe?
Emva kokuba uqoke iimpendulo kule mibuzo, uya kulungele ukuqala inkqubo yokuvavanya iinkqubo ezithile zolawulo lweenkcukacha. Unokufumanisa ukuba iqonga elisezingeni eliphezulu lomsebenzisi lomsebenzisi (njengeSQL Server okanye i-Oracle) kuyimfuneko ukuxhasa iimfuno zakho eziyinkimbinkimbi. Ngakolunye uhlangothi, ideskithophu yedesktop njengeMicrosoft Access inokukwazi ukudibana neemfuno zakho (kwaye kulula ukufunda, kunye ne-poentbook kwikhompyutha yakho!)
Desktop yolwazi
Idesktop yolwazi linikeza isisombululo esincinci, esilula kwiinkcukacha ezininzi zokugcina idatha kunye nokunyanzelisa. Bafumana igama labo ngenxa yokuba baqulunqwe ukuba baqhube kwi "desktop" (okanye kwi-computer). Mhlawumbi uqhelana nemibandela embalwa yale mveliso sele ikhona - iMicrosoft Access, FileMaker kunye ne-OpenOffice / i-Office Office Base (ekhululekile) ngabadlali abakhulu. Makhe sihlole ezimbalwa zeenzuzo ezifunyenwe ngokusebenzisa ideskithophu yedeskithophu:
- Idesktop yolwazi ayinayo. Uza kufumana ukuba izixazululo ezininzi ze desktop zifumaneka malunga no-$ 100 (xa kuthelekiswa namawaka eedola ngenxa yozala babo). Enyanisweni, ukuba unayo ikopi yeMicrosoft Office, usuvele ungumnikazi welayisenisi we-Microsoft Access.
- Iinkcukacha zeDesktophu ziyabasebenzisa. Ukuqonda ngokucacileyo kweSQL akudingeki xa usebenzisa ezi nkqubo (nangona abaninzi bancedisa i-SQL ukuba uyenze khona). I-DBMS yeDesktop idla ngokubonelela ngokucacileyo indlela yokusebenzisa imizobo yomsebenzisi.
- Iinkcukacha zeDesktop zibonelela ngezisombululo zewebhu. Ininzi yolwazi lwangoku idesktop inikezela ngokusebenza kwewebhu ukukunceda ukuba ushicilele idatha yakho kwiwebhu kwifashthi okanye eshukumisayo.
Yolwazi lweServer
I-Server yolwazi, njenge- Microsoft SQL Server , i-Oracle, i-PostgreSQL evulekile, kunye ne-IBM DB2, inika imibutho amandla okulawula ixabiso elikhulu lwedatha ngendlela eyenza abasebenzisi abaninzi bakwazi ukufikelela nokuhlaziya idatha kanyekanye. Ukuba unako ukusingatha itekisi yentengo ephezulu, i-database-based database ingakunika isisombululo esiphezulu sokulawula idatha.
Iintlawulo ezifumanekayo ngokusebenzisa inkqubo ye-server-based ahlukeneyo. Makhe sibone iimbalwa ezimbalwa ezizuziweyo eziphumelele:
- Ukuzinza. I-database-Based database ikwazi ukuphatha malunga naluphi na ingxaki yokulawula idatha ongayiphonsa kuzo. Abathuthuli bayakuthanda ezi nkqubo ngenxa yokuba baneenkcukacha zoqhelwano lweprogramme (okanye ii-APIs) ezibonelela ngokukhawuleza ukuphuhliswa kwezicelo zesithethe eziqhelekileyo. Iqonga le-Oracle lifumaneke nakwiinkqubo ezininzi zokusebenza, ukubonelela i-Linux junkies ngenqanaba lokudlala kwinqanaba xa idibene kunye nabantu baseMicrosoft.
- Ukusebenza okunamandla. I-database-based based database iyinamandla njengoko ufuna ukuba ibe. Abadlali abakhulu bayakwazi ukusebenzisa ngokufanelekileyo malunga naluphi na isicwangciso se-hardware esilungileyo okwazi ukuzakhela sona. IiNgcaciso zanamhlanje zikwazi ukulawula iiprosesa ezininzi, eziphambili, ii-server, ukuxhuma kunye nokukhwabanisa kwikhompyutha.
- Ukusabalala. Esi sibonelo sihamba sisesandleni-sangaphambili kunye neyokudlulileyo. Ukuba uzimisele ukubonelela ngezibonelelo ze-hardware eziyimfuneko, iinkcukacha zeseva ziyakwazi ukusingatha ngokukhawuleza inani elikhulayo labasebenzisi kunye / okanye idatha.
I-NoSQL yeeNgcaciso zeNgcaciso
Ngomfuneko ekhulayo yemibutho yokuphatha iisethi ezinkulu zeenkcukacha ezixakile - ezinye zazo ezingenaso isakhiwo sendabuko - "I-NoSQL" yolwazi luye lwasasazeka. I-database ye-NoSQL ayilwanga kwiikholamu eziqhelekileyo / ukulungiswa komgca weenkcukacha zoluntu, kodwa kunoko isebenzisa imodeli ye-data eguquguqukayo. Umzekelo uyahluka, kuxhomekeke kwisiseko sedatha: abanye bahlela idatha ngokubalulekileyo / ixabiso lesibini, iigrafu okanye iikholomu ezibanzi.
Ukuba intlangano yakho idinga ukunqumla idatha eninzi, qwalasela lolu hlobo lwesiseko sedatha, ngokuqhelekileyo ukulungelelanisa kunezinye i-RDBM kunye nokunye okutsha. Abadlali abaphezulu baquka i-MongoDB, iCassandra, CouchDB kunye ne-Redis.
