Throughout the remainder of this book, we will add replication to this example. We do this to underscore the concepts that we are presenting in this book; the first being that you should start with a working transactional program and then add replication to it. </p> <p> Note that this book assumes you already know how to write a transaction-protected DB application, so we will not be covering those concepts in this book. To learn how to write a transaction-protected application, see the <em class="citetitle">Berkeley DB Getting Started with Transaction Processing</em> guide. </p> <div class="sect1" lang="en" xml:lang="en"> <div class="titlepage"> <div> <div> <h2 class="title" style="clear: both"><a id="appoverview"></a>Application Overview</h2> </div> </div> </div> <p> Our application maintains a stock market quotes database. This database contains records whose key is the stock market symbol and whose data is the stock's price. </p> <p> The application operates by presenting you with a command line prompt. You then enter the stock symbol and its value, separated by a space. The application takes this information and writes it to the database. </p> <p> To see the contents of the database, simply press <code class="literal">return</code> at the command prompt. </p> <p> To quit the application, type 'quit' or 'exit' at the command prompt. </p> <p> For example, the following illustrates the application's usage. In it, we use entirely fictitious stock market symbols and price values. </p> <pre class="programlisting">> ./ex_rep_gsg_simple -h env_home_dir QUOTESERVER> stock1 88 QUOTESERVER> stock2 .08 QUOTESERVER> Symbol Price ====== ===== stock1 88 stock2 .08 QUOTESERVER> stock1 88.9 QUOTESERVER> Symbol Price ====== ===== stock1 88.9 stock2 .08 QUOTESERVER> quit ></pre> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="permmessages.html">Prev</a> </td> <td width="20%" align="center"> </td> <td width="40%" align="right"> <a accesskey="n" href="simpleprogramlisting.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Permanent Message Handling </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Program Listing</td> </tr> </table> </div> </body> </html>
