Not sure what you mean. Say you are an e-commerce business. If you store each page view in your system, it's simple to write a sql query that details where all your visitors are coming from, the path they take to order something, how long it takes them to order something, which users haven't ordered anything or visited the site in the past two weeks, etc. Adding a timestamp to a table doesn't really help here.
