Topic 14 – Introduction to Database Design

Why do I need to learn about database design?

Database is the heart of any software system, especially enterprise systems. A bad database design will eventually cause your system fail.
Designing enterprise databases requires a lot of specific enterprise knowledge and in-depth understanding of structure of big databases.
That's why you need to learn about database design.

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 WHEN you should use a relational database management system or WHEN you should use a NoSQL database management system and HOW they actually work.

That sounds useful! What should I do now?
