The APIs used to implement replication in your application are described here. This book describes the concepts surrounding replication, the scenarios under which you might choose to use it, and the architectural requirements that a replication application has over a transactional application. </p> <p> This book is aimed at the software engineer responsible for writing a replicated DB application. </p> <p> This book assumes that you have already read and understood the concepts contained in the <span><em class="citetitle">Berkeley DB Getting Started with Transaction Processing</em> guide.</span> </p> <div class="sect1" lang="en" xml:lang="en"> <div class="titlepage"> <div> <div> <h2 class="title" style="clear: both"><a id="conventions"></a>Conventions Used in this Book</h2> </div> </div> </div> <p> The following typographical conventions are used within in this manual: </p> <p> Class names are represented in <code class="classname">monospaced font</code>, as are <code class="methodname">method names</code>.
