Temporal Database - (BCA / B.Tech)

Introduction to Temporal Databases in RDBMS:

A Temporal Database is a database that stores data along with timestamps, indicating when specific information was valid or when a change was made. These databases are suited for scenarios where tracking data changes over time is necessary, such as for historical data analysis, validation, and managing time-series data.

Key Concepts:

Valid Time: The time period during which a fact is true in the real world. For example, the valid time for an employee's job position indicates when they held that position.
Transaction Time: The time period during which data was stored or modified in the database.
Bitemporal Data: Data that is tagged with both Valid Time and Transaction Time, providing the most detailed tracking.

Temporal databases enable special queries to ask questions about the state of data at a particular point in time.
