Bitemporal modeling is a data management concept that allows the representation and tracking of changes to data over two different time dimensions: valid time and transaction time. 1. **Valid Time**: This refers to the time period during which a fact is true in the real world. For example, if a person's address changes, the valid time would capture the duration during which each address was valid. 2. **Transaction Time**: This reflects the time period during which a fact is stored in the database.
