Last week we revisited class objects and object oriented designs. Remembering that a is a blueprint for an object we proceeded to figuring out what it is rather than how it works. Classes are defined by their states and behaviors.
We then learned about sessions and query strings.
Sessions are storage units for data while the user is logged in to the web server. When values are entered into the server, the session keeps it confidential so no one else can view your personal details like an account number.
Query Strings are like sessions but more visible to the user. They send information from one page to another but the query strings allows others to view what is being sent over.
