Temporal Databases

Temporal databases are specialized databases that manage data concerning time, allowing users to track changes over different periods. They can store historical data (what was true at that time) and future data (what is expected to be true), enabling complex queries about past events or future forecasts. For instance, a temporal database can record a person's address history, showing where they lived at specific times. This ability to handle time-related information makes temporal databases valuable for applications in various fields, like finance, healthcare, and project management, where understanding change over time is crucial.
