|Don't ask to ask, just ask|
You have hit upon something most experienced developers call "Separation of Concerns". It's the underlying principle behind MVC - Model / View / Controller. (It's called by other names, but that's the most popular.) It was also a driving force behind creation of OO methodologies.
This is usually seen in Perl with the use of templating systems, like HTML::Template or Template Toolkit, for separation of Perl (business logic and engine, or Model / Controller) from output generation (View). Other distributions, such as SQL::Catalog, can help with the separation of SQL (data logic, or Model) from Perl (business logic and engine, or Model / Controller).
Most examples you tend to see are for complete newbies, who just want something to get them up and running quickly. The reason for that is that newbies need to have instant gratication, or they give up. Later, if they are interested, they will do what you're doing - come to those with experience and ask for advice. At that point, you'll improve your code. :-)
Then there are Damian modules.... *sigh* ... that's not about being less-lazy -- that's about being on some really good drugs -- you know, there is no spoon. - flyingmoose
I shouldn't have to say this, but any code, unless otherwise stated, is untested
