RQL — Say what no builder can
This is the part that is not convenience. RowFold's engine already compares periods, breaks a report down two ways at once, walks a relationship without a bridging column, and filters groups rather than records. No single screen of controls can offer all four at once. One sentence can:
Orders
where Status is Won and Amount > 10000
and {Company.Region} is "North West"
during Closed in this quarter vs previous
group by {Company.Region} across Stage
show sum of Amount as Revenue
having Revenue > 50000
sort by Revenue desc limit 20
One grammar, so you learn it once — but not one surface yet. A view carries the table, the where and the sort by, and a view is where the braces open today; the period, the second axis, the measures, the having and the limit are the report half of the same sentence. The grammar reads all of it and the panel prints all of it. Write a clause a view cannot carry and it comes back named, one line per clause — which is the third promise below, and worth checking rather than believing.
