Thanks for the link!
As far as I can tell from a few minutes of reading, their approach uses
the same idea, but starts from C++ classes, where we start from SQL
table definitions. I wonder how changes in the data model look like
(e.g. adding a new column)? We can migrate the database, dump the new
table structure and generate the code.
I'll keep on reading! Thanks again!
