If you have a group of users that needs identical access levels to a database you can use the concept of User groups to more effectively manage their access.
User groups can be understood as roles in the project, if you want to give e.g. the architects or electrical engineers the same access rights you can create a user group and connect the users to that group. All associated users will be given the access you have assigned to the user group. If you change access reight on the User group, all associated users will also change their access right accordingly.
You can create a new User group as a project or owner administrator.
