Answer:
The correct answer to the following question will be "Local mapping".
Explanation:
- A data independence standard in global DBMSs where questions can be constructed without understanding the local formats. Knowledge of quotas of pieces and components is however important.
- With the transparency of local mapping, the user wants to determine both fragment location and name of data items, keeping in mind any replication that may occur.
- This is clearly a more complicated and time-consuming question for all the users to answer than the first. A program that only offers it the amount of transparency would be unlikely to be satisfactory to later part-users.
Therefore, "Local mapping" is the right answer.
