Chapter 6.  Data Discovery Rules 
Data Discovery Rules are questions you ask about the data. These queries can be one 
time only, or they can be converted into System Policies that are tracked over time. 
Data discovery rules come in five varieties: 
Comparative 
query 
A comparative query compares one attribute of one entity on one node to the 
same attribute of the entity on another node. One example is comparing the 
list of file sharing members of one group on one node to the same list on 
another node in your system. All items from both nodes are returned. 
Distinct 
Comparisons 
A distinct comparison query finds items that are missing or different from one 
node to another. An example is non-matched Safeguard globals. Only the 
distinctly different items are returned. 
Distinct Query 
A query that distinctly looks for specific information or mis-matching data that 
is unexpected. For example, a duplicate binder timestamp between 
programs. Binder timestamps are normally distinct, unless expected to be 
matching.  
Orphan Query 
An orphan query compares two sets of data looking for non-matching values. 
For example, an orphan query comparing the list of users of a system to the 
list of users who own files on the system will produce a list of files that are 
owned by userids not the system, called Orphan Files. 
Value-based 
query 
A value-based query compares an attribute of one entity to a value. One 
example is comparing the read, write, execute and purge security attributes 
of the Guardian files entity to a value of “NNNN”, producing a list of all files on 
the system with a security of “NNNN”.
