  9. TPS–OnlineTransactionProcessingSystems WithOLTPand Web technologiessuchas an extranet,suppliers canlook atthefirm’s inventory levelor productionschedule in real time.  Thesuppliersthemselves,in partnershipwith theircustomers, canthen assumeresponsibilityforinventory management and ordering.  InteractiveInternetTPS expandsOLTPto provideenhancedreal timetransactionprocessingover the Internetor intranets. 

  10. TypicalOLTPEnvironments Airline/RailwayReservationSystems BankingSystems(ATM,EFT, ...) Tradingand BrokerageSystems Hotel/ HospitalSystems Reservationsystems:set aside service/product future use for Point-of-sale(POS) terminals:sellsgoods/services Libraryloan systems:keeps track ofitems borrowed fromlibrary

  11. ACIDPropertyofTransactions Atomicity: Either allupdates are performedor none Consistency:Ifthe databasestateat thestart ofa transactionis consistent,itwill be consistentatthe endofthe transaction Isolation:When multipletransactionsare executed concurrently,thenet effectis as though each transactionhas executedin isolation Durability:Aftera transactioncompletes(commits), its changesare persistent

  12. Transaction States Partially Committed Committed Active Failed Aborted

  13. Transaction A  transaction can haveone of two outcomes: If it completessuccessfully,thetransaction saidtohave committedandthedatabase reachesanewconsistentstate. is If it does notexecute successfully,the transactionis aborted. Thisis knownas roll-back. 
