Imagine that a technique called snapshot isolation database is being used to keep a bank's database secure.Do you have an example that illustrates how a nonserializable execution might be detrimental to the bank?
Suppose a transaction deletes a record, and the free space generated thus isallocated to a record inserted by another transaction, even before the first transaction commits.a. What problem can occur if the first transaction needs to be rolled back?b. Would this problem be an issue if page-level locking is used instead oftuple-level locking?c. Suggest how to solve this problem while supporting tuple-level locking,by logging post-commit actions in special log records, and executing them after commit. Make sure your scheme ensures that such actions are performed exactly once.
Is a stable database state possible, and if so, how can it be achieved? There is no guarantee that the transaction's symbolic meaning accurately captures the underlying real-world event, and this is where the DBMS fails. Exactly what are the ramifications of such a ban? Give an illustration of what you mean. Does the term "serializable transactions" really mean what it appears to?
Consider the following case: Does the failsafe database need a recovery manager, and if so, why?
Some database systems allow the administrator to choose between two forms of logging: normal logging, used to recover from system crashes, and archival logging, used to recover from media (disk) failure. When can a log record be deleted, in each of these cases, using the recovery algorithm of Section 19.4?

Suppose you wish to create an audit trail of changes to the takes relation. Can the preceding implementation guarantee that updates made by a malicious database administrator (or someone who manages to get the administrator’s password) will be in the audit trail? Explain your answer.
How do shadow paging and write-ahead logging methods differ in terms of database recovery?
The Oracle database system uses undo log records to provide a snapshot view of the database under snapshot isolation. The snapshot view seen by transaction Ti reflects updates of all transactions that had committed when Ti started and the updates of Ti; updates of all other transactions are not visible to Ti. Describe a scheme for buffer handling whereby transactions are given a snapshot view of pages in the buffer. Include details of how to use the log to generate the snapshot view. You can assume that operations as well as their undo actions affect only one page.
