In Module 2, we explore the relational model, a cornerstone concept in database design. This module will guide you through understanding how relational tables are structured, differentiating them from non-relational tables, and introducing essential relational terminology. You'll learn about the significance of keys, including primary and foreign keys, and how they are fundamental in establishing and navigating relationships within a database.
Understanding Relations and Keys: We delve deeper into the relational model by examining how entities are represented in tables and how attributes and relationships are defined. The module will cover the characteristics of relations, ensuring you understand how tables are composed and the importance of key constraints in maintaining data integrity. By the end of this module, you'll have a solid foundation in how databases use relations and keys to organize data effectively and efficiently.
