<p style='MARGIN:0in 0in 0pt;LINE-HEIGHT:150%' class="Section1"><span style='COLOR:black'>This tutorial provides a step-by-step lesson on developing
component-based distributed applications using <a href="http://www.dre.vanderbilt.edu/cosmic/">CoSMIC</a> modeling toolkit and the
<a href="http://www.cs.wustl.edu/%7Eschmidt/CIAO.html">CIAO DAnCE</a>
framework. The example application used in this tutorial is a Stock Quoter that
consists of two components; the <i>StockDistributor</i> and the <i>StockBroker</i>.
The <i>StockDistributor</i> notifies one or more stock brokers whenever a stock
price changes. Upon receiving the notification, the <i>StockBroker</i> fetches
information about a particular stock from the <i>StockDistributor</i>. The
figure bellow shows the application diagram. This Stock Quoter application is
based on a series of <a href="http://www.cs.wustl.edu/%7Eschmidt/report-doc.html">CORBA component
model</a>
columns written by <a href="http://www.cs.wustl.edu/%7Eschmidt/">Doug Schmidt</a>
and <a href="http://www.iona.com/hyplan/vinoski/">Steve Vinoski</a> for <a href="http://www.cuj.com">C/C++
Users Journal</a> and has consistently been
used as an example for <a href="http://www.cs.wustl.edu/%7Eschmidt/TAO.html">TAO</a>.<o:p></o:p></span></p>
