How Do You Handle Many-to-many Relationships In A Relational Database? Are you curious about how to manage complex relationships between data entities in a relational database? In this video, we'll explain the best way to handle many-to-many relationships, a common challenge in backend development. We’ll start by discussing what many-to-many relationships are and why they can cause issues such as data duplication and complicated queries. Then, we'll introduce the concept of a join table, also known as a junction table, which acts as a bridge between two main tables. We’ll show how creating a third table with foreign keys referencing the primary keys of related tables simplifies data management. You’ll learn how to set up this table with a composite primary key to ensure unique data entries and how to write efficient queries to retrieve related data easily. This approach keeps your database organized, reduces redundancy, and improves data consistency. Whether you're building APIs or managing complex data connections, understanding this method is essential for creating scalable and maintainable backend systems. Join us as we walk through practical steps to implement this technique effectively and keep your database structure clear and efficient.
