This post to get users opinion regarding the content of the graph :

*1-Should the graph be simplified as today: to display the columns with predicates and aggregates / order by clauses (without any function), to be a kind of ER diagram*

or

_2-Should the graph be as close as possible to the SQL: with to_date, case, concat …

**functions displayed**as arithmetic opérations and other details/i]
