Association rules Completing the New or Save As form
About  New  Data Access  History

Purpose

Create an association rule by selecting Association from the SysAdmin category.

Be sure to use a short but meaningful prefix for each association that correctly describes the relationship between the classes, since association names are used to prefix property names in the Report Viewer and the Report Definition form.

An association rule has two key parts:

Field	Description
Applies To	Select a class that this Association rule applies to. The classes you can enter here may depend on the RuleSet you select. On the Restrictions tab of the Class form, a class rule may limit rules applying to that class to belong to one of an explicit list of RuleSets.
Prefix	Select a prefix for this association rule. Start with a letter and use only letters and digits. Don't enter a prefix that is a SQL reserved word (such as SELECT, ORDER, or JOIN).

For general information about the New form, see Completing the new rule dialog box. For general information on the Save As form, see How to enter rule keys using Save As.

Rule resolution

Partial rule resolution applies to association rules. When searching for association rules, the system:

• Filters candidate rules based on a requestor's RuleSet list of RuleSets and versions
• Searches through ancestor classes in the class hierarchy for candidates when no matching rule is found in the starting class

Circumstancing and time-qualification features are not available for association rules.
