Not buying it. Your abstraction in the code is independent of the DB
scheme.

If orders arrived over SMTP, would you require them to have a To, From,
Subject and MessageID?

Like we can have length(list) and length(vector): processed differently,
same name.

Even if it turns out that you actually need a different data type for
single orders versus basket orders, they could have the same named
methods for the common thing.

Moreover, if the single order type actually uses the same data structure
to represent the list of orders as a basket order (e.g. a list of one
item), then they can probably share a lot of code in the base class.

Just dealing with the DB schema and whatnot can be specialized
to the specific type.

If the relevance of this remark is to confirm that your development
shop is daft, I assure you that it is redundant.
