A DerivedDbAttribute is a DbAttribute that resolves to an SQL expression based on a set
of other attributes. DerivedDbAttribute's allow to build expressions like "
<code>count(id)</code>", "<code>sum(price)</code>", etc.
<p>
Internally DerivedDbAttribute is defined as a specification string and a set of
substitution DbAttribute parameters. Specification string is an SQL expression that
contains placeholders (<code>%@</code>) for attribute parameters, for example:
</p>
<p>
<code>sum(%@) + sum(%@)</code>
