- What exactly is a reversible schedule? Why is it desirable for schedules to be recoverable?Is it ever appropriate to enable nonrecoverable schedules? Explain your response.HelloI hope to answer my question and don't use your handwriting, pleaseThank you Tru the answer to be unique with references please What is a recoverable schedule? Why is the recoverability of schedules desirable?Are there any circumstances under which it would be desirable to allow nonrecoverable schedules? Explain your answer.I would appreciate it if you could list and quickly explain each of the three processes that went into the physical design.When executing duties related to database recovery management, you are free to use these three backup levels in any combination you see fit. What precisely is the purpose of each additional level of backups that is performed?
- Why is the use of access modifiers so crucial when working with OOP? What advantages does this option have over others? Specify the circumstances in which you would employ them.Is the following schedule a serializable schedule? Explain your answer.What is requirement of transaction status and intention list entries in a recovery file?
- In a nutshell, describe the three physical design processes.The administration of database recoveries might use all three of these backup levels. To what end do we have backup levels?In the case that the database has to be restored, what are the three distinct varieties of backups that may be deployed in this process? To put it simply, what precisely is the role that each succeeding level of backups is supposed to play?Answer the following by giving proper justification and examples:(i) Are all serializable schedules conflict-serializable?(ii) Are all conflict-serializable schedules view-serializable. explain in detail;
- Concisely describe the three stages of physical design.Any of these three levels of backups may be used for database recovery management. For what reasons do we create incremental, daily, and nightly backups?Distinguish between differential and incremental backups, with a focus on database backups and restores, as well as their dependability (do they always work?).In contrast with a sequential file organization, would it be possible to keep the records in multiple sequences? Why or why not?
