[teiid-issues] [JBoss JIRA] Commented: (TEIID-871) Refactor system vdb

[Steven Hawkins (JIRA)]

    [ https://jira.jboss.org/jira/browse/TEIID-871?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12496418#action_12496418 ] 

Steven Hawkins commented on TEIID-871:
--------------------------------------

Once 6.3 changed to 7.0, these changes went further:

1. all properties tables were collapsed into a single table.
2. the terms model/group/element were replaced with schema/table/column
3. the usage of full name and upper name was removed since these were derived and potentially misleading since the name may not be sql safe (needing quotes)

> 1. We should remove the system physical model - it's undocumented, exposes too much metadata cruft, and requires too much logic in the index connector to support it.
> 2. We should remove System.datatypeelements and System.datatypeelementproperties - the transformations are invalid (they will always return no rows) and they are redundant 
> 3. There should be a new system table ProcedureParamProperties that exposes annotations for procedure params.
> with System.element/datatype and the corresponding properties tables.
> 4. This one is open to debate, but I would also like to remove System.describe - since annotations are available directly on the appropriate type table, there doesn't seem to be a good reason to introduce a procedure that operates over all metadata records to return the same information.
> 5. The OA ODBC views should be moved into a separate vdb that can be optionally including along with the system vdb
