Why do I need to learn about database design?

Database is the heart of your application, especially enterprise applications. Designing a database incorrectly will cause your application eventually fail.

What can I do after finishing learning about database design?

You will know how to design a relational database and write SQL code PROPERLY. You will know how to build a data warehouse. You will know WHY you should use a relational database system and how it actually works.

That sounds useful! What should I do now?
