About Bitemporal Data Model

The Bitemporal Data Model maintains two timelines—transaction time (when data is recorded in the database) and valid time (when the event actually occurred)—unlike Non-Temporal or Uni-Temporal models. It enables tracking data history, meeting audit requirements, and flexible time series analysis, but introduces complexity in query design, data consistency (e.g., preventing overlapping valid times), and application logic when implemented in relational databases.
