Description: A mapping table is a data structure that defines the relationships between different data elements, facilitating the organization and access to information in databases. In the context of databases, these tables are fundamental for establishing connections between various entities, allowing for data normalization and reducing redundancies. Mapping tables can contain primary and foreign keys that link records from different tables, enabling complex queries and efficient retrieval of interrelated information. Additionally, these tables are essential in implementing relational data models, where the goal is to maintain referential integrity and ensure that relationships between data are consistent and accurate. In summary, mapping tables are key tools in database management, providing a structured framework for data interconnection and optimizing the performance of queries.
