Yes, I am aware of this.
Now, my question regarding this, becomes, which of the available options would you recommend? In addition to Apache::DBI, I have seen Class::DBI, Rose::DB::*, and DBIx::Class. And I am sure there are others that I haven't seen. According to what I have read so far, Rose::DB::* will use Apache::DBI if it is available (i.e.installed and loaded), but the others as far as I can tell would be competitors that do the pooling and more. But it is my understanding that each of these provide connection pool handling, and are thus competitors that do more. Are you aware of anyone who has done an objective comparison of the available options, looking at feature sets, relative performance, code maturity, &c.? It would be useful for guys like me to see such a review, in order to focus on studying those packages that will provide the biggest benefit for the time spent. NB: This isn't a question of which is better, but, rather, which provides the best fit to what a given developer is looking for (much as I would choose C++ for some applications and Perl for others, and Java for still others, depending on the problem domain).
