Answer:
Databases are not that simple. Now we not only have a Data warehouse, but we also have the Data Lake as well. We also have NoSQL and SQL form of support with these modern databases. The JSON format is rocking. You can hence through JSON store the text, image, audio, video, etc in one go. And like the first five can be a text, the next five can be an image then again a text than video, and so on. And it is super easy to access them as well. Also, you can edit them quite easily as well. It's not that hard like the Lisp used to be in the past. And supermarket has a mix blend of the database. And modern databases like Data Lake can be very useful, undoubtedly.
You can store security type of requirements, like CCTV footage, each shop details like shop ID, Product list, shop type, electricity bill, hours of opening, floor, facilities, no. of employees, etc., and like this, we can have the details for the entire supermarket, and each shop there definitely. And we can perform various actions on behalf of each shop and market as well. The database can hence be very useful definitely

Answer:
Option (B) i.e., Hash is the correct option.
Explanation:
A hash value is the number that has the fixed length and the data recognition is uniquely. It is also a type of file that is read by the special type algo, it uses the value of the bits in the following computer files which is used to manipulates the single number. That's why the following option is correct.
Answer:
Option b is the correct answer for the above question.
Explanation:
- The mystery function is a recursive function that calls for the two times when the user passes 38 on the argument.
- The first value is 38 and the second value is 2 for which that function is called.
- When the value 38 is passed, then again 2 is passed because of the "mystery (n % 3);" statement.
- This statement holds by the if condition which gives the true when the argument value is greater than 2.
- Hence for the 2 value the if condition will not true and the function is not called again.
- Then the 38/3 and 2/3 are printed whose value is 12 0, but it will print 0 12 because of the recursive function.
- Hence option b is the correct answer while the other is not because other options does not states the output of this program.
