2. What’s a Web Service?
   Most web applications use a
   Database to store their data
   and a Front-End to present it.
   The Web Service connects
   the Front-End to the
   Database enabling it to
   access stored data.

3. Why are Web Services useful?
   Using an extra layer as a way to provide data to
   your app reduces complexity and improves
   maintainability
   Separating data from the front-end makes it easier
   to work with a team
   When done right, services are accessible from any
   platform as they are based on open standards
