UC is a Governance tool.

If you have structured or semi-structured data in Volume, you can view the data by using the select statement.

select * from csv.`/Volumes/folder/file.csv`;  (backtick)
select * from json.`/Volumes/folder/file.json`

Once you are convinced you can create a table 

create table <> as select * from csv.`/Volumes/folder/file.csv`; 

Its not possible to find the schema on unstructured data.
