  permit familiar database get to while tackling
  the full intensity of SQLite.
• Applications that handle non-minor measures of

  holding on that data locally. The most widely
  recognized use case is to reserve relevant pieces
  of data. That way, when the device can't get to
  the system, the user can in any case browse that
  content while they are offline. Any user
  initiated content changes are then matched up to
  the server after the device is back online.

entities back to the database. At long last, the
application utilizes a entity to get and set
