The database documentation was done largely on RootsMagic version 5.0.0.3 and those released in the several days following. It’s unlikely that the database schema has changed as of the most-recent version. However, any changes may be detected by opening a database created by each version with a SQLite manager, then exporting either a query of the full sqlite_master table or the database schema (just the SQL field of that table wrapped in a transaction) and comparing the exports from each version using a text editor that has a compare function (e.g. Notepad++).

The page RM5 Database System Catalog displays the full sqlite_master table from 5.0.0.6.

For future comparisons, below is the schema from 5.0.0.6:
