In terms of database design, class design, and many other programming tasks, it is often useful to restrict your concept of numbers to there being only three numbers:
For example: never design a database that can store two e-mail addresses for a contact. It should store none, one, or many. Now, your interface might restrict people to entering a "sensible" number of e-mail addresses like two, or six, or ten, but the database design should stick with none, one, or many.

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).
