Ans: Components such as users, actions, relationships, and resources constitute access control in any Web Sphere Commerce application. Actions are the activities that users perform on the available resources. For controlling the purposes of access control, actions must be grouped into relevant groups.
E.g., the common action in any online store is a view, which is invoked to display a page to the customers. Views used in the store are declared as actions and should be assigned to an action group prior to allowing access.
Two types of access control, based on policy: resource-level and command-level access control are practiced. A resource-level access control policy is applied to establish if the user needs to access the resource. Command-level access control confirms whether the user should be allowed to execute the particular command within the specified store.
