In relational databases, relationships are used to link different tables based on common attributes. These relationships define how data in one table is associated with data in another, ensuring data integrity and enabling efficient querying and data manipulation. The three primary types of relationships in relational databases are one-to-one, one-to-many, and many-to-many. Each type of relationship is implemented using keys, such as primary keys and foreign keys, to establish these connections between tables. Understanding and properly implementing these relationships is crucial for database design, as it ensures that data is organized logically, minimizes redundancy, and maintains consistency across the system. This article explores the types of relationships in relational databases, their applications, and how they contribute to the effective management of data in various domains such as e-commerce, finance, and healthcare.
