About This MicroSim

This graph models role-based access control (RBAC) the way a graph database stores it. Users are assigned roles, roles inherit permissions from more general roles (a Cardiologist inherits everything a Physician can do; an ICU Nurse inherits from Nurse), and roles grant specific permissions like reading clinical records or writing orders. An access check — "can Dr. Chen write orders?" — becomes a traversal from the user through her roles and their inherited roles to the granted permissions.

How to Use

Follow a user's HAS_ROLE edge to their role, then the dashed INHERITS_FROM edges up the role hierarchy, and finally the GRANTS edges to the permissions that role confers. Trace how Dr. Chen, as a Cardiologist, inherits the Physician role and so gains read, order-writing, and lab permissions, while the Billing Clerk role grants only billing access. Drag nodes and use the navigation buttons to explore the hierarchy.
