Could we agree on the following small changes to the model you posted last week? 1. Rename InstanceGroupPolicy to InstanceGroupPolicyUse 2. In InstanceGroupPolicy[Use], rename the "policy" field to "policy_type" 3. Add an InstanceGroupPolicyUseProperty table, holding key/value pairs (two strings) giving the properties of the policy uses 4. Color all the diamonds black Thanks, Mike -------------- next part -------------- An HTML attachment was scrubbed...
