# App Sample

Version: 1.0 | Release Date: 30/6/2018

# Things to know

Our app example is a simple book borrowing program that contains two main objects: Book and Member

  1. The member's profile stores his borrowing history
  2. The Available Property of Book decided whether it can be borrowed or not
  3. Each book has an ISBN number that checks its validity each time it is saved.
  4. Users can also manually check the ISBN before saving.
  5. Add a Printing Report to the Member
  6. Add a EBI Report to the Member

You can download the runable code of the entire app from github (opens new window)
