As an example of a filesystem access that is transaction dependent: When I create a new supplier in the database, I need a set of directories built on the file system. If the directories are not there, it will cause a lot of problems when dealing with this supplier. When creating the supplier, I use a trigger to build the directories, and if it can't then it will error out, roll back the supplier insert and give an error to the user that they cannot build the directory structure and to please speak with IT to resolve the issue.
