Learn to translate business needs into a data model.
What you’ll learn
Explain what relational database is
Understand how to avoid problems that can happen when we store data in tables
Design a database model that meets business needs and avoid data storage problems
Prepare your data model for actual database construction.
In this foundational course, we begin by teaching you the basics of relational databases and how they work. You will then learn the process of data modeling–translating a set of business needs into a visual “entity relationship diagram” that can be used to create a database. You won’t actually create the database in this course–this is primarily about the data modeling process.
What is most valuable about this course is the way that it will teach you to translate business requirements into data models using hands-on projects! We will work with two imaginary clients who will give us a set of business requirements. We’ll create diagrams to serve their needs and modify the diagrams as their business needs grow and change. In short, you will learn data modeling skills by DOING data modeling.

1. An Introduction to Relational Databases:
Components of Relational Databases
