1.	Which of the following timestamps is used to record the time when a transaction has finished its read phase?(a) Start(i)(b) Validation(i)(c) Finish(i)(d) Write(i)I have been asked this question in an interview for job.I'm obligated to ask this question of Validation Based Protocols in portion Concurrency Control of RDBMS
Answer» Right option is (b) Validation(i) Easy EXPLANATION: There are three different timestamps for each transaction START(i), validation(i), finish(i). The validation phase is used to record the TIME at which a transaction has FINISHED its read phase and has STARTED its validation phase.
