Databases are universal - they underlie the technology you use every day. They're a crucial component of everything from telecommunications systems, banking systems, and video games to just about any other software system that maintains some amount of persistent data.

In this course, you'll learn about the fundamental concepts of databases, why and when they're used, what relational databases are, and entity-relationship diagrams. You will also be exposed to techniques like normalization that help to increase the efficiency of databases. You'll wrap up with a look at the basics of Structured Query Language (SQL). 

After completing this course, you will be able to move onto more advanced courses involving database systems and SQL.

Database Design Fundamentals for Software Engineers

Be able to characterize the level of redundancy in a relational schema

Provide mechanisms for transforming schemas in order to remove redundancy

What is/are the goals of normalization?

Any dependency A → B in a relation, A should be a super key.

A relation must not contain any partial dependency

The domain of an attribute must include only atomic (simple, indivisible) values 

A relation must not contain any transitive dependency
