The access model in TIS is very fine grained and there are over 130 different permissions in the core system alone. The business extensions may also introduce additional permissions to the system. Event though there is a large number of permissions, they are well organised and their structure is logical. There are about 30 different pre-defined roles, which makes it easy to give each user a functional set of permissions so that they can do complete their worktasks.
TIS extends the basic RBAC model by introducing groups. In addition to giving users roles, roles can be added to a group so that all user members of that group will gain the roles.
