This is my favorite view on the blog.  It contains is an instance-wide list of tables, complete with table size in number of rows and number of bytes.

It does have many dependencies, all of which can be found on this blog.
                vwPartitionRaw
                vwDictCol
                SpaceUsed
                vwObjectFileGroup
         udfPadLeft()
                udfFormatInteger()

This object is referenced by various other objects in this blog.
