I’ve this class diagram train in UML. The primary drawback was the permissions are the works, which I didn’t know very nicely the best way to mannequin it. The specification says:
Customers can publish their work on a web site for exterior customers. On this
course of the work will likely be geared up with a Net service interface.
The atmosphere can have a Net system in order that customers exterior the
firm can simulate simulation work for a charge. Net customers should
establish themselves to entry the totally different works.
Exterior customers could request permission to simulate the totally different works
on the Net system, to acquire mentioned permission they have to pay the value
that the corporate has established for every work . The system will maintain
the date wherein the simulation permission of every work was granted
to every exterior person. As soon as permission has been granted, exterior
customers will be capable to run the work as many instances as mandatory, the
system will retailer the variety of runs of every work that every exterior
person has carried out.
The answer I had raised is the next diagram:
However I’ve some doubts: are entry permissions and exterior person jobs represented appropriately?
