The integration of SQLite into MyRent to replace the file io system follows easily from the SQLite demo lab presented last week. The DBHelper class ports without any changes. Removal of the file io artefacts is trivial as are changes to the model.

In the MyRent series of labs we have used file storage as a means of data persistence. In an earlier lab we introduced an SQLite database to an app based on a subset of MyRent.Here we replace the file system in MyRent with an SQLite database. Later we shall open up this database to other applications using Android's ContentProvider.
