Rule Trees

Rule Trees

A rule tree represents the organizational structure of rules and rule folders. The position that you assign a rule or rule folder within the rule tree determines the order in which the Rule Engine processes the rule. You build conditional relationships between rules through the rule tree.
A rule tree can be a connection rule tree or a security rule tree. Each rule tree uses a system of folders and rules to determine the hierarchical order for rule processing.
When the Dynamic Data Masking Server receives a connection request, the Rule Engine parses the request through the connection rule tree. If the connection rule assigns a security rule set, then the Rule Engine parses the SQL request through the security rule tree. The security rule set defines the security techniques that the Rule Engine applies to rewrite the SQL statement.
