This module covers relational databases, ER modeling, functional dependencies, normalization, and managing data coherence, integrity, and constraints.

Become a Database Professional with SQL

In this interactive module, you’ll learn the fundamentals of relational databases and explore relational design and mapping.

You'll start with an overview of relational databases and database keys, then explore concepts like functional dependencies and normalization (1NF, 2NF, 3NF) to improve data consistency, coherence, and efficiency. As you progress, you'll explore integrity rules, constraints, and data modeling using entity-relationship diagrams (ERD) to a relational schema. You'll then apply key SQL concepts, including data manipulation, CSV to SQL import, aggregate functions, SQL joins, and subqueries.

By the end of this module, you'll be able to design efficient databases and write optimized SQL queries for real-world applications.
