Intersection Magic requires read/write access to the IM database files on the operating system level.
Intersection Magic opens database files in read/write mode in all cases. Built-in security may be used to further control access to the database files.
User access to IM databases can be managed through Utilites/Users menu in Intersection Magic. Users may be granted read and/or write permission to the database. This access is only enforced within Intersection Magic.
