Common Types of Relationships
In database design, relationships are used to connect data stored in different tables. The primary types of relationships include:
- One-to-One: Each row in one table corresponds to exactly one row in another table.
- One-to-Many: A single row in one table corresponds to multiple rows in another table.
- Many-to-Many: Rows in one table can correspond to multiple rows in another table and vice versa.
Understanding these relationships helps in designing normalized databases that reduce redundancy and ensure data integrity.
Understanding Relationships in Database Design
In database design, understanding the different types of relationships between data entities is important for creating efficient and effective databases. These relationships define how data in one table relates to data in another, influencing how data is structured, stored and retrieved. The three most common types of relationships are one-to-one, one-to-many and many-to-many.
In this article, We will learn about each Type of Relationship with the example and implementation in detail.
