The most basic part of a web application is the
data itself. As I said earlier, all web applications
allow a user to submit instructions on how the web application
should massage a bit of data on the web server. This might
involve searching a database, creating a shopping cart of
products, or emailing some information to someone.

Regardless, the data which is being manipulated all has some
basic characteristics.
- Data have values
- Data have types
- Data have descriptions
- Data have formats
All of the web technologies at the Data Layer define,
describe, or standardize one or more of these
characteristics.
