Both a and b
Answer is Right!
Answer is Wrong!
The correct answer is: Both a and b.
If a piece of data is stored in two places in the database, then storage space is wasted and changing the data in one spot will cause data inconsistency.
- Storage space is wasted because the same data is stored twice. This can be a problem if the data is large or if the database is storing a lot of data.
- Changing the data in one spot will cause data inconsistency because the two copies of the data will no longer be the same. This can be a problem if the data is important or if it is used by multiple applications.
To avoid these problems, it is important to design databases carefully and to use appropriate data management techniques.
