  • Amasistimu okucubungula okwenziwayo aqinisekisa ubuqotho nokuthembeka kwedatha ekusebenzeni kwebhizinisi.
  • I-Scalability ivumela ukuphatha amanani aphezulu okwenziwayo ngaphandle kokuba nomthelela ekusebenzeni.
  • Izakhiwo ze-ACID zibalulekile ekuqinisekiseni ukuthengiselana okuthembekile nokubuyiselwa ekuhlulekeni.
  • Ukusebenzisa izinyathelo zokuphepha eziqinile kubalulekile ekuvikeleni ulwazi olubucayi ngaphakathi kwama-SPT.
Amasistimu Wokucubungula Okwenziwayo

Esikhathini solwazi lwedijithali, ama-transaction processing systems (TPS) adlala indima ebalulekile ekulawuleni ukusebenza kwebhizinisi. Lezi zinhlelo azigcini nje ngokusiza ukulandelela ukuthengiselana kwedatha ngaphakathi kwesizindalwazi, kodwa futhi ziqinisekisa ubuqotho nokuthembeka kwedatha. Lesi sihloko sicubungula izici ezibalulekile zezinhlelo zokucubungula okwenziwayo, ihlola izici ezifana nobuqotho bedatha, ukukala, ukwethembeka nokuphepha.

Ubuqotho Bedatha

Ubuqotho Bomzimba Nobunengqondo

Ubuqotho bedatha bubalulekile kuma-SPT. Ihlukaniswe yaba ubuqotho bomzimba, okuvikela idatha phakathi nokugcinwa nokubuyiswa, kanye nobuqotho obunengqondo, okuqinisekisa ukuthi idatha ithobela imithetho nemikhawulo yebhizinisi.

Ubuqotho obuyinkomba kanye Nobuqotho Bebhizinisi

Ubuqotho obunengqondo buhlukaniswe yaba ubuqotho obuyinkomba, obugcina ubudlelwano phakathi kwedatha, nobuqotho bebhizinisi, obugxile ekunembeni kwedatha ngayinye.

Ukuvimbela Inkohlakalo Yedatha

Ama-SPT kufanele avikele ekukhohlakaleni kwedatha, okungabangelwa iphutha lomuntu, ukwehluleka kwezingxenyekazi zekhompuyutha, noma ukuhlasela okunonya. Lokhu kubalulekile ukuze kugcinwe ukunemba nokuba wusizo kolwazi.

Ukwehluka

Ukuzijwayeza kumavolumu okwenziwayo

I-SPT enwebekayo iyakwazi ukuphatha ukwanda kwenani lemisebenzi ngaphandle kokuphazamisa ukusebenza. Lokhu kubalulekile ekukhuleni kwebhizinisi kanye nokwaneliseka kwamakhasimende.

Scalability Strategies

Kubandakanya ukuhlukaniswa kwedatha nokucubungula okufanayo, kokubili okubalulekile ekuphatheni amavolumu amakhulu wedatha kanye nemisebenzi yokufunda kuphela.

Ukubaluleka Kwezakhiwo ze-ACID

Ukuqina futhi kuncike ku-ACID (i-atomicity, ukungaguquguquki, ukuzihlukanisa, nokuqina), okuqinisekisa ukuqhubeka nokuthembeka kwedatha.

ukwethembeka

Ukuhambisana Nezakhiwo ze-ACID

Ukuthembeka kwe-SPT kuncike ekubambeleleni kuzakhiwo ze-ACID, eziqinisekisa ubuqotho bokwenziwe kanye nokululama ekuhlulekeni.

Ukubekezelelana Kwamaphutha

Ukufaka ukubekezelela amaphutha ekwakhiweni kwesistimu, njengokuphinda kwenziwe kabusha kanye nezipele, kubalulekile ukuze kukhuliswe ukwethembeka.

Inkumbulo Yokwenziwayo kanye Nokugeleza Kokuthola Okuthembekile

Lezi zindlela zivumela ukutholwa kwamaphutha kanye nokutholwa, okuqinisekisa ukuthi izimo zokwenziwayo ziyagcinwa ngisho nasezimeni ezimbi.

Ukuphepha

Ukuvikelwa Kolwazi Olubucayi

Njengoba ama-SPT aqukethe ulwazi olubalulekile, kubalulekile ukusebenzisa izinyathelo zokuphepha eziqinile, ezihlanganisa ihadiwe, isofthiwe, nokuphepha ngokomzimba.

Imininingwane Yokwenziwayo

Ama-SPT kufanele anikeze ukufinyelela okuvikelekile nokulawulwayo kuzinqolobane zolwazi ukuze kuvinjelwe ukuchayeka okungafanele kanye nokusetshenziswa kwedatha.

Izinyathelo zokuphepha

Kubandakanya izinqubomgomo eziqinile zephasiwedi, ukubethela kwe-SSL/TLS, nezinqubo zokwenza isipele nokutholwa ukuze kuvikelwe ekulahlekeni kwedatha nezinsongo kubuqotho besizindalwazi.

Imibuzo Evame Ukubuzwa mayelana Nezinhlelo Zokucubungula Izinto

1. Buyini ubuqotho bedatha kumasistimu okucubungula okwenziwayo?

Ubuqotho bedatha kuma-transaction processing systems (TPS) bubhekisela ekunembeni, ukungaguquguquki nokuthembeka kwedatha ngokuhamba kwesikhathi. Ihlukaniswe ngobuqotho bomzimba, okuvikela idatha ngesikhathi sokugcinwa nokubuyiswa, kanye nobuqotho obunengqondo, okuqinisekisa ukuthi idatha ihambisana namazinga nemikhawulo esungulwe yinkampani.

2. Inkohlakalo yedatha iwathinta kanjani ama-SPT futhi ivinjelwa kanjani?

Ukonakala kwedatha ku-PTS kungabangela ukulahlekelwa okukhulu, izinqumo ezingalungile nezinkinga zokusebenza, njengoba kuthinta ukunemba nokuba usizo kolwazi. Ivinjelwa ngokusebenzisa izinyathelo zokuphepha, ukunganaki kwedatha, ukuqinisekiswa kanye nezilawuli zokufinyelela ukuze kuncishiswe ubungozi bephutha lomuntu, ukwehluleka kwehadiwe noma ukuhlaselwa okunonya.

3. Kusho ukuthini ukuthi i-SPT ikhule futhi kungani ibalulekile?

I-SPT enwebekayo yileyo engakwazi ukubhekana nokukhuphuka kwevolumu yokwenziwe ngaphandle kokulahlekelwa ukusebenza kahle noma ukusebenza. Lokhu kubalulekile ekukhuleni kwenkampani kanye nokuzivumelanisa nezimo emakethe eshintshayo, okuyivumela ukuthi ikwazi ukuphatha ukuthengiselana okwengeziwe njengoba ibhizinisi landa.

4. Yiziphi izakhiwo ze-ACID ku-SPT futhi yini ukubaluleka kwazo?

Izakhiwo ze-ACID (Atomicity, Consistency, Isolation, and Durability) kuma-SPTs ziqinisekisa ukuthi konke okwenziwayo kucutshungulwa ngendlela enokwethenjelwa. Lezi zakhiwo ziqinisekisa ukuthi okwenziwayo kuyaphela noma cha (Atomicity), kugcina ubuqotho bedatha (Ukungaguquguquki), kusebenza ngokuzimela kwezinye izinkokhelo (Isolation), futhi kuhlala kungashintshiwe uma sekuqediwe (Ukuqina).

5. Yiziphi izinyathelo zokuphepha ezibalulekile kuma-SPT?

Izinyathelo zokuphepha ezibalulekile kuma-SPT zifaka ukusetshenziswa kwamagama ayimfihlo aqinile, ukubethela kwe-SSL/TLS ukuze kuvikelwe ukudluliswa kwedatha, izinqubomgomo zokufinyelela ezinemikhawulo, ukucwaninga okujwayelekile kokuvikela, amakhophi asenqolobaneni, nezinhlelo zokuhlenga izinhlekelele. Lezi zinyathelo zivikela idatha ekufinyeleleni okungagunyaziwe, ukukhohlisa nokulahlekelwa.

6. Ukubekezelela amaphutha kunomthelela kanjani ekuthembekeni kwe-PTS?

Ukubekezelela amaphutha ku-PTS kuqinisekisa ukuthi isistimu iyaqhubeka nokusebenza kahle ngisho noma kwenzeka ukwehluleka kancane. Lokhu kufezwa ngokudicilelwa phansi kwehadiwe ne-software, kanye nokugcinwa kwedatha nezindlela zokuthola kabusha. Lezi zinyathelo zivumela ukululama ngokushesha nangempumelelo, kugcinwe ukuqhubeka kwebhizinisi nokuvikela ubuqotho bedatha.

Isiphetho

Izinhlelo zokucubungula ukuthengiselana zibalulekile ekusebenzeni kahle nangokuphephile kwezinqubo zebhizinisi. Amandla azo okuqinisekisa ubuqotho bedatha, ukulinganiswa, ukuthembeka, kanye nokuphepha kubalulekile ezweni eliya ngokuya likhula ngedijithali. Ukuze kugcinwe ukuncintisana kanye nokusebenza kahle, kubalulekile ukuthi amabhizinisi atshale imali ezinhlelweni zokucubungula ukuthengiselana eziqinile neziguquguqukayo. Yabelana ngalesi sihloko ukuze wandise ulwazi mayelana nokubaluleka kwezinhlelo zokucubungula ukuthengiselana ezweni lebhizinisi.
