Though not really software (programming) related but I always feel that having a good grasp in database is important in software development nowadays as almost all software use database extensively, except gaming to some extent though.

It is also good if we intend to sell our Malaysia-made software (database based most of the time, I presume) as a world class solution.

Cheers.
