Some tables in your consolidated database may have rows that belong to many remote databases. Each remote database has a subset of the rows in the consolidated database and the subset overlaps with other remote databases. This is frequently the case with a customer table. In this case, there is a many-to-many relationship between the table and the remote databases and there is usually a table to represent the relationship. The scripts for the download_cursor and download_delete_cursor events need to join the table being downloaded to the relationship table.
