Consider the precedence graph of Figure is the corresponding schedule conflict serializable? Explain your answer.
Answer to relevant QuestionsWhat is a recoverable schedule? Why is recoverability of schedules desirable? Are there any circumstances under which it would be desirable to allow nonrecoverable schedules? Explain your answer.Most implementations of database systems use strict two-phase locking. Suggest three reasons for the popularity of this protocol.Locking is not done explicitly in persistent programming languages. Rather, objects (or the corresponding pages) must be locked when the objects are accessed. Most modern operating systems allow the user to set access ...For each of the following protocols, describe aspects of practical applications that would lead you to suggest using the protocol, and aspects that would suggest not using the protocol:• Two-phase locking• Two-phase ...Compare the deferred- and immediate-modification versions of the log-based recovery scheme in terms of ease of implementation and overhead cost.
