the database server crashed. Assume all logged operations completed before the crash. Assume we are using the deferred update method with a write-ahead transaction log. Remember that in this setting, working memory (buffer) is only written to persistent disk during the CHECKPOINT operation, users only receive confirmation of a successful transaction after a COMMIT, and changes to the database are only made in working memory after a COMMIT. When the database server restarts, which actions, if any, should be performed to recover the database? Provide an explanation for your answer the database server crashed.
