Because serving the data in the decomposed format gives the consumer the
maximum flexibility to do as they wish with the data. I find it hard to
see why, as a relational database guy, you'd want to offer the data as
"8.1", "8.1.3" etc. when you can just give the three parts separately
and allow people to check whatever they need without having to chop up
strings!

Imagine wanting to display only the details of the 8.x releases on a
site for example. In your schema, you'd have to use a substring match on
an attribute value to filter out 6.x and 7.x.
