[dna-issues] [JBoss JIRA] Commented: (DNA-576) SImple JPA Model Does Not Support Transparent Referential Integrity

    [ https://jira.jboss.org/jira/browse/DNA-576?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12498425#action_12498425 ] 

Randall Hauch commented on DNA-576:
-----------------------------------

I'm not convinced that this is terribly important feature to have in the connector.  The 'Basic' model's referential integrity feature only works with content stored in the database; federation of multiple sources requires performing referential integrity at a higher level than the connector.  As such, the JCR implementation will likely use the query/search functionality to identify references as part of its referential integrity checks.

> One feature in the basic model that has not yet been carried forward into the simple model is the ability to store references from one node to another in a transparent entity external to the node entity.  This allows for database foreign keys to help enforce referential integrity at the graph level.  However, since the primary consumer of DNA graph information at this time is the JCR layer, it may not be necessary to add this feature (and its associated performance cost at this time).
