Uhanjiselo-Server Architecture

ukwakhiwa loNiko-server - yiyo lwesakhiwo sesebe le-womnatha okanye yathunyelwa, apho kukho eyahlukileyo iseva kunye namacandelo ngekhompyutha (Client), lwahlulwe phakathi umthwalo womnatha computing, ebavumela ukuba basebenze kunye. Amaxesha amaninzi, intsebenziswano ye-server-based uthungelwano kunye umxhasi nge yenethiwekhi computer. Njengoko iseva kunye lomxhasi kuba izixhobo kuphela ngekhompyutha kwakunye isoftware okanye izicelo.

womnatha weNgingqi iseva ezinikeleyo

ukwakhiwa client-server kusenokubonisa isakhiwo apho umthengi ezininzi (idla malunga ezilishumi)   computer apho ezinikele elektroniki esembindini unit - umncedisi. Loo iqela bezixhobo zombane kuthiwa "ariya yobulali yomsebenzi womnatha kunye umncedisi ezingcwele."

Umlawuli wenethiwekhi unelungelo mda ukutshintsha uqwalaselo lomncedisi. Oku uyakwazi ukufaka nayiphi na inkqubo yokusebenza, ngokunjalo nokugcinwa esiludumbo engundoqo. Le database ulwazi olusisiseko kungenziwa akhiwe kwi kumncedisi computer, kwaye (ngenxa yezizathu zokhuseleko) ngayo nayiphi na isixhobo elektroniki ukuba yinxalenye yothungelwano. Indawo Idathabheyisi iseva yeWebhu Kulula kakhulu kuba ngale ndlela iqinisekisa ekuqhubekekeni kukuzingisa zonke iikhompyutha kwi-network ngexesha umsebenzi zobugcisa le web usembindini matshini.

Network nge umncedisi ezinikeleyo ngokuqhelekileyo isicelo ukwenzela ukuqinisekisa okungenamida kutshintshiselwano lwedata phakathi kwamasebe yentlangano enkulu okanye inkampani. Enye ukusetyenziswa kwale lwezakhiwo has indawo uthungelwano imidlalo yekhompyutha. Oku kukuqinisekisa oluqhubekayo ufikelelo non-siwumise lokudlala kunye nenethiwekhi.

Iklayenti - i inkqubo yekhompyutha

Igama elithi "ukwakhiwa uhanjiselo-server 'zanele kunye nokusasazwa network kwezithuthi phakathi kwezi client kunye neseva, apho umxhasi yinkqubo yekhompyutha. Kulo mzekelo, zonke iinkcukacha ezibuthathaka ifumaneka e-central iinkcukacha ezigcinwayo kwi enamandla server computer. Ukuqwalasela ulwazi kunye nokhuselo wayo nazo zibonelelwe yi esiludumbo umncedisi. Esi sakhiwo sombutho kuluncedo kakhulu kuba umncedisi ibe ngcono kwaye zithembeke ngakumbi ukukhusela data olubuthathaka ukusuka iinzame olungagunyaziswanga ukuzuza ukufikelela kubo a kakhulu. Kumncedisi, wabeka ulawulo lokungena, ngenxa apho, iinkcukacha luvuleleke kuphela kubasebenzisi, sanikwa amagunya athile.

Imithetho-siseko ekwakheni lwezakhiwo client-server

ukwakhiwa loNiko-umncedisi ukwakhiwa ngokwimiselo:

1. compound Dual, ngokubonelela umncedisi we web kunye abathengi elinesibini.

2. compound izithathu ofelwe i (Web site) intermediate isakhiwo ephakathi iseva kunye client. Le yunithi lisebenza njenge umlamleli ekusetyenzweni izicelo kunye data okanye ukukhusela lokufikelela kulwazi, ngokunjalo ukhuselo layo umonakalo kwintshabalalo. Kulo mzekelo, inani kwiindawo abasebenza okanye udlala kwi-network ye nokuba kakhulu ukwanda.

3. Connection N-ngeenyawo, ukwenza uqhagamshelwano kunxibelelwano abancedisi web ezininzi. Inani labo kuxhomekeke kwizinga umthwalo womnatha. Inani iikhompyutha ukuba bangasebenza ikhonsati kuthungelwano, kakade, ngaphezulu kakhulu. iiseva esiPhakathi ngokuqhelekileyo enikwe igama "iseva database", "iseva application".

Ngoko ke, lo womnatha wobulali kunye ezimbaxa nezintsonkothileyo lobume abancedisi N-ezininzi nabathengi ezininzi yenza umsebenzi ongcono ergonomic ngakumbi zonke iinxalenye kwisekethe network.
