Description: A subtable is a table that is part of a larger table structure. In the context of databases, subtables are used to organize and structure data hierarchically or relationally. These tables can contain information that is related to a main table, allowing for better management and access to data. Subtables are especially useful in relational database systems, where the goal is to maintain data integrity and avoid redundancy. By dividing information into subtables, complex queries can be executed more easily, and storage efficiency is improved. Additionally, subtables can be used to represent one-to-many or many-to-many relationships between different entities, allowing for a clearer and more logical representation of data. In summary, subtables are a fundamental tool in database design, as they enable more effective organization and faster access to related information.
