Iindlela NoSQL ingaba na ibango
Kwi-computer science, kwaye ingakumbi isiseko sedata, intengiselwano efana booking, ukuthenga okanye intlawulo yi-uphunyezwe nge-ukulandelelana ka-imisebenzi leyo shenxisa-database kwimo phambi intengiselwano ukuba urhulumente B, posterior kwaye iindlela elisetyenziselwa ukufumana ukuba oku ukulandelana ngu kunye atomic, lwesivumelwano, isolated kwaye durable (ACID)
Uninzi database management system ngokwezimali i-data njengoko relational yentengiso, ukuvumela abantu ukwenza eyenziweyo atomic, lwesivumelwano, isolated, kwaye durable.
Ingcamango ka-intengiselwano lusekelwe i-notion ka-wokwenza ngaxeshanye incopho (ngaxeshanye a), oko imele iityuwadefault colour imeko computer system mbasa, balaseleyo, zayo data.
Umzekelo, xa i-ulwazi lo msebenzi ukuba ukukhutshelwa kwemali evela omnye bank i-akhawunti kwenye ibhanki i-akhawunti, kukho umsebenzi ka-ukungazibandakanyi ka-mali ukususela imvelaphi i-akhawunti kwaye idiphozithi ngomhla ekujoliswe kuwo-akhawunti. I ikhompyutha lwenkqubo ukuba wenza oku intengiselwano iya kuqinisekisa ukuba u-imisebenzi kusenokuba lwenziwa ngaphandle impazamo, kwaye kule meko, tshintsho luza siqalile kwi-u-akhawunti. Zombini ii-akhawunti kuzigcina yabo yokuqala amaxabiso.
Oku kuqinisekisa data ukungaguquguquki kwesiqulathi phakathi u-akhawunti.
Oku yamandulo technique practiced kunye ii-ezinye, ezifana CICS ukusuka IBM, TOS senkunzi enye, MTU, Siemens, namhlanje widely asetyenziswa architectures ka-web izicelo, kwaye umxhasi-umncedisi izicelo. Ingxaki kule indlela umsebenzi kukuba ngamanye amaxesha a ukulandelelana eziliqela screens okanye amaphepha ukuphuhlisa olugqityiweyo intengiselwano ACID. Lo methodology Merise, apho sele okokuqala, ochaziweyo ezi concepts: Lo msebenzi sibonwa ukuba ibe pseudo-intengiselwano ka-a ka-okubonakalayo ziqwalaselwe ngu-intengiselwano technique, kodwa kunjalo ngenene na lwempahla ethengiswa njengoko ixesha elide njengoko ukulandelelana ayikho esikolweni.
I-responses of owokuqala bamele kanjalo abo ezisetyenziswa namhlanje kwi - 'elitsha' ubugcisa: kulula ukuqonda ukuba kutheni sino ezinye indlela amacango (DBMS) kuba wonke ukulandelelana, ixesha apho ufumana uncontrollable, inkqubo ingaba nazo. Ukuba ngu-wonke incopho ka-i pseudo-ezinye Kodwa isicwangciso-buchule ye-ulawulo isolation ngu basically lwempahla ethengiswa.
I pseudo-intengiselwano ufumana okuninzi ACID, kodwa lwempahla ethengiswa imithetho enjalo ukuba coherence phakathi ngamnye pseudo-intengiselwano a ukulandelelana ngu guaranteed yi kubekho i-uhlaziyo lomgaqo-database. Umxhasi-aplikeshini umncedisi kuhle yenzelwe, kanjalo isebenzisa pseudo-eyenziweyo, kodwa kwimeko encomekayo kwi-umxhasi isicelo, apho relieves zonke umncedisi. I-schema uhlobo ngu zilandelayo.
