Review Comment:

log entry who touched what and when.
MV creation is technically a table creation with some extra metadata. The
same API is called and each time a table/mv is created a new entry is inserted
into the `NOTIFICATION_LOG` table:
In this example `emp` is a table `mv1` is a materialized view.
```

```
Could this be used for audit?
