<p>Some of these words <em>are emphasized</em>.
Some of these words <em>are emphasized also</em>.</p>

<p>Use two asterisks for <strong>strong emphasis</strong>.

<p>This is the second paragraph in the list item. You're

<li><p>Another item in the same list.</p></li>
<li><p>A list item with a blockquote:</p>

<p>Here is an example of AppleScript:</p>

<pre><code>tell application "Foo"
    beep
end tell
</code></pre>

<p>This is an <a href="https://example.com/">example link</a>.</p>

<p>I get 10 times more traffic from <a href="https://google.com/" title="Google">Google</a> than from
<a href="https://search.yahoo.com/" title="Yahoo Search">Yahoo</a> or <a href="https://search.msn.com/" title="MSN Search">MSN</a>.</p>

<p>I start my morning with a cup of coffee and
<a href="https://www.nytimes.com/">The New York Times</a>.</p>

<p>I strongly recommend against using any <code>&lt;blink&gt;</code> tags.</p>

<p>I wish SmartyPants used named entities like <code>&amp;mdash;</code>
instead of decimal-encoded entites like <code>&amp;#8212;</code>.</p>

<p>If you want your page to validate under XHTML 1.0 Strict,
you've got to put paragraph tags in your blockquotes:</p>

<pre><code>&lt;blockquote&gt;
    &lt;p&gt;For example.&lt;/p&gt;
&lt;/blockquote&gt;
</code></pre>

<h3>Phases of Software Development</h3>

<ol>
<li>Analysis</li>
<li>Design</li>
<li>Implementation</li>
</ol>

<h4>Analysis phase</h4>

<p><em>Requirements</em> -- what the customer wants or needs.  Understanding on needs expressed by:</p>

<ul>
<li>Use cases can (can use UML)</li>
<li>User manual style of analysis document</li>
</ul>

<h4>Design phase</h4>

<p>Goals of OO design:</p>

<ol>
<li>Identify classes -- things in the system</li>
<li>Identify responsibilities of the classes</li>
<li>Identify relationships between classes</li>
</ol>

<p>Classes consist of:</p>

<ol>
<li>Behavior: Methods represent the class behavior</li>
<li>State: Fields represent the state of the class instance (object)</li>
<li>Identity:  each unique object should have its own address in memory
which contains its state</li>
</ol>

<p>Types of classes that are common:</p>

<ol>
<li>Tangible things</li>
<li>Agents</li>
<li>Events and transactions</li>
<li>Users and roles</li>
<li>Systems</li>
<li>System interfaces and devices</li>
<li>Foundational classes</li>
</ol>

<p>Types of class relationships:</p>

<ol>
<li>Dependency (<em>uses a</em>)</li>
<li>Aggregation (<em>has a</em>)
<ul><li>Aggregation -- 1:many</li>
<li>Association -- 1:1</li>
<li>Composition -- "<em>if I'm composed of other things, then I am considered
responsible for the lifetime for those things</em>"</li></ul></li>
<li>Inheritance (<em>is a</em>)</li>
</ol>

<p>Classes and relationships are the basis for a UML class diagram.</p>
