Hi;
Going through the core patterns book.
There is a bad practice dedicated to not using finder methods when large
result is expected but use a DAO instead.
My understanding is that the authors want to have a 'dual interface' for
access to the same data, Modeling the data itself as entity beans yet using
DAO for the search. Is this correct?
If so, wouldn't this be in contrast to resusability? Also, isnt this a good
place to put your money on vendor container optimiations?
