OrpheusORM has a built-in schema engine, which you can ,optionally, use to create and/or update your schema, based on your model classes.
By default Orpheus assumes that your table names will match your model class names. But you can override this assumption, by decorating your model classes with the [TableName] attribute and essentially map your model to the database table.
Using an OrpheusModule you can save nested data (master-detail-subdetail) with just one Save. All master-detail relationships and keys will be updated automatically.
