Answer to Question 1

TRUE

Answer to Question 2

Time dependent data can be modeled using a time stamp. This can be used to maintain a history of the changes over time. Often times, the way that relational databases deal with time dependent data is not adequate and organizations ignore the issue or use simplified methods such as time stamps.
