Over the course of a day, a department performed multiple DML statements (inserts, updates, deletes)on multiple rows of data in multiple tables. The manager would like a report showing the time, table name,and DML type for all changes that were made. Which Flashback technology would be the best choice to produce the list?
A. Flashback Drop
B. Flashback Query
C. Flashback Transaction Query
D. Flashback Versions Query
E. Flashback Table
The Flash Transaction Query could provide the data requested in a single query.Option A is an invalid choice because the table wasn't dropped.Option B is incorrect because Flashback Query returns data at only a specific point in time,not for a range of times.Option D is incorrect because,although it could produce the data needed for the report,Flashback Versions Query would hvae to be run for each table individually.Option E is incorrect because the user does not want to recover the table at all.
