Welcome to Relational Database Design! This course expounds upon the concepts covered in the course, Introduction to Relational Database, where you learned the fundamentals. In this course, you will focus on the design aspects of databases and explore practical examples to help you apply the concepts to real world scenarios. To help you concentrate on effective design, this course will be more theoretical and conceptual. You will not actually build the databases with software applications. You will do that in the course, Relational Database: Implementation and Applications. Sounds exciting, right? Let's begin with an overview of database design covering three main lessons: 1) Entity-Relationship (E-R) modeling, 2) E-R diagrams, and 3) Extended ER features and relation schemas. Please review the module learning objectives below and refer them as a guide for your learning.
