The pseudo-code for the way I imagine implementing this is something like:
use DataBaseDriver;
...
use constant CITIES => qw(lon par);
use constant APPLICATIONS => qw(test prod);
# build dispatch table for database handles
my %db_handle;
for my $city (CITIES) {
for my $app (APPLICATIONS) {
$db_handle{$city}{$app} = DataBaseDriver->new
or die "'$city:$app' driver creation failed: ",
DataBaseDriver->error_msg;
}
}
...
# use database handle dispatch table
my $msg = '...';
my $city = '...';
my $app = '...';
my $dbh = $db_handle{$city}{$app}
or die "'$city:$app' driver access failed";
$dbh->store_to_database($msg);
...

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
