• Validation

• Validation is checking to see if what the user entered is correct or makes sense. It can be done 2 ways:

• Client Side

• Server Side

• Fast: it is performed without sending the data to the server
• Incomplete: cannot compare values to something on the server

• Slow: data must go to server and back
• Comprehensive: all server information is available to compare entries against
