This book describes the concepts surrounding replication, the scenarios under which you 61 might choose to use it, and the architectural requirements that a replication application has over a 62 transactional application. 63 </p> 64 <p> 65 This book is aimed at the software engineer responsible for writing a 66 replicated DB application. 67 </p> 68 <p> 69 This book assumes that you have already read and understood the 70 concepts contained in the 71 <span><em class="citetitle">Berkeley DB Getting Started with Transaction Processing</em> guide.</span> 72 73 </p> 74 <div class="sect1" lang="en" xml:lang="en"> 75 <div class="titlepage"> 76 <div> 77 <div> 78 <h2 class="title" style="clear: both"><a id="conventions"></a>Conventions Used in this Book</h2> 79 </div> 80 </div> 81 </div> 82 <div class="toc"> 83 <dl> 84 <dt> 85 <span class="sect2"> 86 <a href="preface.html#moreinfo">For More Information</a> 87 </span> 88 </dt> 89 </dl> 90 </div> 91 <p> 92 The following typographical conventions are used within in this manual: 93 </p> 94 <p> 95 Structure names are represented in <code class="classname">monospaced font</code>, as are <code class="methodname">method 96 names</code>.
