Data redundancy:
- Data redundancy is the presence of repeated data in the storage device. It consists of duplicate data that is additional to the actual data.
- In this, the data related to a folder can be seen in other folders also. For example, file related to science folder can be seen in mathematics or social.

For each of the three primary methods of file management that you're outlining, please provide illustrative examples.
What does the phrase "file handling" refer to, and why are its services
necessary in the first place? Please include as many details as
possible
How many records does the file contain? How many fields are there per record?
What problem would you encounter if you wanted to produce a listing by city? How would you solve this problem by altering the file structure?
If you wanted to produce a listing of the file contents by last name, area code, city, state, or zip code, how would you alter the file structure?
What data redundancies do you detect? How could those redundancies lead to different types of anomalies?

We have a database file with six million pages (6,000,000 pages), and we want to sort it using external merge sort. Assume that the DBMS is not using double buffering or blocked I/O, and that it uses quicksort for in-memory sorting. Assume that the DBMS has six buffers.
