Where do you specify database connectivity? That is, where to find the
tables? (type of database, username, password, schema name if needed,
or for CSV files the directory they are located in).
For "real" databases, can a "table" really be a "view"?

Xypron,
Summarizing our discussion I would like to propose the following
syntax:
table T IN "string", "string", ... :
S <- [ I, J, ... ], p ~ P, q ~ Q, ... ;
where 'S <-', '~ P', '~ Q' can be omitted;
table T { domain } OUT "string", "string", ... :
expr ~ A, expr ~ B, ... ;
where '~ A', '~ B' can be omitted.
I think this syntax is sufficient for most practical cases.
If you find it acceptable, I could start making necessary changes in
the translator.
Best regards,
Andrew Makhorin
