Traditionally what I have done is abstracted all the SQL queries that I 
want to use into a "class" (read: package) and call those "methods" 
usually as functions (returning arrays of data). The reason for this is 
that my programs' SQL queries cover a database's contents very sparsely 
but specifically and, compared to the size of said database, in a very 
limited way. An ORM would not have gained me a huge amount of time or 
enough other "goodness" to make it worth the effort learning that ORM's 
foibles.

I now find myself needing to provide something that could, in the limit, 
replicate some C programs that are able create arbitrarily complex 
"reports", that will be punted into a Mojo webserver for onward service 
to a punter. The punters in question will not be using SQL :-).

The SQL required will cover a much larger range of the tables (as well 
as quantities of data) in the database, even for the first cut which 
will simply webify some existing excel "reports". But the webification 
only amounts to providing that data in JSON and punting it down a 
websocket. (Oh and the original screen of course, but that is out of 
scope for this discussion).

It has to be said that my instinct would be with Abigail. But the very 
fact that I am asking the question means that I recognise that some 
OOish view of this database might be useful.

Obviously, if this system that I am starting now ends up where I think 
it will, I could simply generate SQL queries on the fly and hide them in 
some real (generated) classes and carry on like that. It is very likely 
that this, in the first instance, also a reasonable possibility.

The decision could turn either way at the moment.
