data validation - missing data

[lezawang]

Hi
I am reading one article about data validation and it says: "if a user accidentally enters the wrong date or data is missing we want to be able to set in place some rules of checking that information, this is known as validation."

My question, can we use data validation to make sure user did not miss any data? for example, in the table below, I want user to enter ID and the Name and then starting date. If user miss starting date for John then can not go to next line. or if a user enter ID and then miss the name then he/she can not go to starting date column. Is that possible? Thank you so much.
