Let me see if I got this straight...

Suppose I have an online store where I sell goods to several different countries each using its own currency. I could say (for Brazil's case):

my $real = new Currency;
$real->name('Real');
$real->country('BR');
$real->dolarValue(1.81);

And repeat this as many times necessary for each country. Then use set everything up, and use DBI to get the items from a shopping cart as usual (name, price, other attributes). Then my app would work as if my currency variables had been declared at startup, so I wouldn't have to do a 'select' myself to find out what the price of an item was in Reals?

That's a bit confusing... Let me try this instead.
Instead of doing two selects (one for the product, and one for the currency), I could have the currency loaded as an object and do my select on the product as if the currency information had always been there?

• 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).
