When moving to a services architecture, where do the JOINs go?
? SELECT cnt
> FROM o JOIN c ON o.cid = c.cid
> AND o.aid = a.aid
> WHERE c.cid = 17;
Who do you ask? What does this do to connect the dots? How do you do reporting ("Show me all top 10 articles by country, zipcode digit 1 by week over the last 52w")?
