IBM does not recommend it, but does allow it, i.e. let the SQE execute queries where a DDS described logical file is specified.

Specifying a DDS described logical file in a SQL statement is not a
good idea (and never was).
Actually, IBM does recommend it now...
There is a nice whitepaper about indexing and statitisc strategies
written by Kent Milligan and Mike Cain, which should be learned "by heart".
Here is the link:
That's a great white paper, but it hasn't been updated since 2011..
It appears IBM has move the information into Infocenter and kept it updated..
