Log-based recovery and the shadow-copy scheme have different overheads when data are added to new disk pages. For this comparison, look at how much time each scheme takes (in other words, there is no old value to be restored in case the transaction aborts).
When data is being added to freshly created disc pages, compare log-based recovery with the shadow-copy technique in terms of overheads (in other words, there is no old value to be restored in case the transaction aborts).
Think about using a snapshot isolation mechanism for the bank's database. Banks may run into trouble if executions are not serializable.
To what end does it make more sense to store passwords in a hashed file as opposed to an encrypted database?
Discuss the challenges of maintaining synchronization and consistency in a distributed file system. How do techniques like distributed locks and two-phase commit protocols address these challenges?
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?
The number of encryption operations needed to transfer a big file is comparable in block chaining and feedback modes.When comparing two choices, how much more productive is one over the other?
Distinguish between differential and incremental backups, with a focus on database backups and restores, as well as their dependability (do they always work?).
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.
The variable-length record format makes use of a null bitmap to indicate that an attribute is empty. In certain odd cases, the majority of a tuple's properties are empty. By switching to a one-bit representation of records, we can make null attributes far more affordable.
The amount of encryption operations required to transfer a big file is comparable in block chaining and feedback modes.By what percentage does one solution outperform another?
