Описание: What Is Referential Integrity In SQL? In this informative video, we will cover the concept of referential integrity in SQL and its importance in maintaining data organization and accuracy within databases. Understanding referential integrity is essential for anyone working with relational databases, as it ensures that relationships between tables remain consistent and reliable. We will break down the key components, including primary keys and foreign keys, and explain how they work together to enforce data validity.

Additionally, we will discuss practical examples to illustrate how referential integrity functions in real-world applications, such as e-commerce platforms. You will learn about various rules that help maintain this integrity, including cascade delete, cascade update, restrict, and set null. Furthermore, we will compare SQL databases with NoSQL databases, highlighting the differences in how these systems handle data consistency and relationships.
