That Human Touch: Contact Manager and Client-Side Persistence
We all know that storing information for any length of time in a relatively robust way will usually lead to a database of some sort. In web applications, storing state on the server, whether in a database or in a session, is pretty much expected of most applications.

You almost certainly know that storing nontransient information on the client leads most usually to cookies. We’ll be looking at cookies in just a little bit for sure.
