#1: A maximum of 100 users can log in at one time, but the maximum number of simultaneous accesses to the Item management database is 10. Therefore, if 11 or more users simultaneously access the Item management database, response might become slow.
#2: It is assumed that an average of 20 users and roles are registered for one permission. If the Item management database reaches the maximum size, it might become impossible to set access permissions even if the limit is not exceeded.
#3: If the Item management database reaches the maximum size, it might become impossible to create or edit Items even if the limit is not exceeded.
#4: If the number of times an Item was edited reaches the limit (5,000 times), or if the Item management database reaches the maximum size, Items cannot be escalated even if the escalation limit is not exceeded.
#5: This value includes the number of times an Item is escalated.
#6: It is assumed that the average size of files attached to an Item is 256 kilobytes. If the Item management database for storing attached files reaches the maximum size, it might become impossible to create Items with attached files even if the file size limit is not exceeded.
#7: It is assumed that one process uses an average of 20 Item forms. If the Item management database reaches the maximum size, it might become impossible to change an Item form even if the limit is not exceeded.
#8: If the Item management database reaches the maximum size, it might become impossible to create users or roles even if the limit is not exceeded.
#9: It is assumed that an average of 100 users are registered for one role. If the Item management database reaches the maximum size, it might become impossible to register users for a role even if the limit is not exceeded.
