 These views are designed to make debugging your Redshift cluster more straightforward. They are, in effect, materializations of the [Diagnostic Queries for Query Tuning](http://docs.aws.amazon.com/redshift/latest/dg/diagnostic-queries-for-query-tuning.html) from Redshift's documentation.
 
-- [queries](models/views/queries.sql): Simplified view of queries, including explain cost, execution times, and queue times.
-- [table_stats](models/views/table_stats.sql): Gives insight on tables in your warehouse. Includes information on sort and dist keys, table size on disk, and more.
+- [redshift_admin_queries](models/views/redshift_admin_queries.sql): Simplified view of queries, including explain cost, execution times, and queue times.
+- [redshift_admin_table_stats](models/views/redshift_admin_table_stats.sql): Gives insight on tables in your warehouse. Includes information on sort and dist keys, table size on disk, and more.
+- [redshift_admin_dependencies](models/views/redshift_admin_dependencies.sql): Simplified view of pg_depend, showing any dependent objects (views) for a given source object
 
 These views are designed to make user privilege management more straightforward.
 - [users_table_view_privileges](models/views/users_table_view_privileges.sql): Gives insights into which [privileges](https://docs.aws.amazon.com/redshift/latest/dg/r_HAS_TABLE_PRIVILEGE.html) each user has on each table/view.
