"Another important characteristic of Profile datasets in CJA is their lack of temporal tracking. Instead of tracking state changes over time or being tied to a specific point in time, Profile records in CJA reflect the most recent user data. Operating on a last-value overwrite basis, new data replaces any previous data. This ensures that Profile datasets always represent the most current state of the user's data."
