Hi, is there a problem calling ID's different when used as a FK vs table ID?
For example
mydimtable ()IDnamedescription
myfacttable () my_dim_id # FK to ID above total_sales
I 'think' if I don't enforce foreign key constraints, then this practice
prevents tools from being able to generate ERD diagrams right?

Pretty sure _all_ ER diagramming tools rely on the DDL of column constraints not the names. And personally I would name the column mydim_id. i.e don't inject the extra underscore which is not in your table name. (And I assume the table names are fake: you don't really want "table" in table name)
