Persistence:

• Adding a new book will create a book and will add it to the server-side database and the local one
• Displaying the list of books will require a syncronization of the local database to the server-side database and a request from the local database of all the stored books
• Updating the current reader and location of a book will be done by modifying the corresponding book entity from the server-side database
• Deleting a book will be done by removing that book from the server-side database

No server access:

When the device si offline, the local database is used instead and whe the connection to the server is restored, the local database is being synced with the sever-side database
