informix link help needed

[Christine Weiss]

Hi,

I'm real close to fully understanding the informix-grass link, but I need help in trying to figure out how the maps are linked with the database.  What is and how do you create the spatial data key which is associated with the RDBMS key?

Is it simply the attribute number (for vector)?  How does informix know that this is the link?

Thank you for any help,
