Excuse me, but I don't understand your question.

ContentProvider is designed (a one of it's aims)to wrap access to your tabels. Design of database schema is up to you.

Generally, you need to:

1. Define your tables/ It should be made by execution of sql command in class which extends SQLiteOpenHelper
2. Define an uri for them
3. Define a logic for queries to this tables as it was made for NOTE_ID

Update For JOIN operations SQLiteQueryBuilder is usually used. In setTables() you need to write names of tables with JOIN clause, e.g.

.setTables(NoteColumns.TABLENAME +
            " LEFT OUTER JOIN " + TopicColumns.TABLENAME + " ON " +
            NoteColumns.ID + " = " + TopicColumns.ID);
