Write a program that stores names and dates of birth in a database. Extend the program so that it stores the format of the data in the database; in other words, create a system catalog. Provide an interface that makes this system catalog accessible to external users.
What will be an ideal response?
Again, the program can be written in any suitable language. It should then be modified to add the
data format to the original file. This should not be difficult, if the original program is well
structured. The interface for other users operates on the data dictionary and is separate from the
original program. A menu-based interface is adequate.
