What is a validation rule?
In a database it is important that data is put in accurately. One method of doing that is to use validation rules to restrict what people can put in. So you might have a school where children have to be over a certain age before they can join.

A validation rule will stop them making an error and with the Validation Text, it will give them a message telling them what their error is.
