I'm developing a generic user management system using role based access control(RBAC) were i couldn't distinguish between the operations table and the permissions table(that is after reading so many articles).
"A subject can have multiple roles. A role can have multiple subjects. A role can have many permissions. A permission can be assigned to many roles. An operation can be assigned many permissions. A permission can be assigned to many operations."
can anyone please give a simple example to distinguish between them?
