While it is possible to work directly with SQLite, using Using Room as SQL object mapping library should be preferred. The usage of Room largely simplifies the handling of databases. Using the database APIs as described in this section, provides several challenges The API is relatively low level, and requires a large amount of development time and effort. Raw SQL queries can not verified at compile time. A lot of boilerplate code is required to convert between SQL queries and data objects.
