Administrator User Guide

Data Access Control (DAC) : Example Perops

The following examples show how you can set up Perops to allow a Role to perform various tasks.

Example 1: A Simple Example

This Role allows a user to perform all operations on Pipes, Branches and Piping components.


Perop	Elements	Operations			Attributes
AllPipes	Pipe Hierarchy	Modify Create Delete Claim Issue Drop Output Export Copy	Allow Allow Allow Allow Allow Allow Allow Allow Allow		ALL

Example 2: Hanger & Support Administration

This Role allows a user to create and use Sites for the Design Hangers & Supports application, but not to access Sites for other purposes.

The user must first create a Site, and set its PURP attribute to 'ADM'.

There are three Perops: the first lets the user do everything with Sites except delete them; the second prevents the user changing the PURP of an existing Site; the third lets the user do everything to Sites which have their PURP attribute set to 'ADM'.


Perop	Elements	Operations			Attributes
SuppMaster	Site	Create Modify Delete Claim Issue Drop	Allow Ignore Disallow Ignore Ignore Ignore		PURP NAME FUNC DESC


Perop	Elements	Operations			Attributes

Perop	Elements	Operations			Attributes
SuppDelete	Site	Create Modify Delete Claim Issue Drop	Ignore Allow Allow Allow Allow Allow		PURP NAME FUNC DESC
Condition:	(purp of site eq 'ADM')
