For what purpose is a calculated attribute typically used?

A calculated attribute is typically used to derive values based on other attributes within an entity. This allows developers to create dynamic data that reflects changes in real-time, rather than storing static values. For instance, if an entity has multiple numeric attributes, a calculated attribute could be implemented to compute the sum or average of these numbers automatically. This enhances data integrity and reduces redundancy as the computed results are always up-to-date based on the source data.

This function is crucial in scenarios where real-time analytics or summaries are required without requiring manual updates. By relying on calculated attributes, applications can maintain efficient data models while providing users with relevant information derived from existing datasets.
