Temporal Relational Model

The Temporal Relational Model is an extension of the traditional database model that tracks not only current data but also its history over time. It records when data was valid or changed, allowing you to see how information has evolved. For example, it can store a employee’s salary changes over the years, showing both the values and the specific periods they were in effect. This approach helps organizations analyze trends, make informed decisions, and maintain accurate historical records, making data more dynamic and context-aware.
