+Day 3 Assignment: Ported to Phone Device from TV Device. Implemented rdbStore capability to store and retrieve registered user data. Supports insertion of data through registration page (handling of duplicate email Id during registration) and reading of data through login page (handling of non-existent email Id in database and incorrect password).
