It is intended to describe how to 61 transaction protect your application's data. The APIs used to perform this task 62 are described here, as are the environment infrastructure and administrative tasks 63 required by a transactional application. This book also 64 describes multi-threaded <span>and 65 multi-process</span> DB applications and the requirements they 66 have for deadlock detection. 67 </p> 68 <p> 69 This book is aimed at the software engineer responsible for writing a 70 transactional DB application. 71 </p> 72 <p> 73 This book assumes that you have already read and understood the 74 concepts contained in the 75 <span><i class="citetitle">Getting Started with Berkeley DB</i> 76 guide.</span> 77 78 79 </p> 80 <div class="sect1" lang="en" xml:lang="en"> 81 <div class="titlepage"> 82 <div> 83 <div> 84 <h2 class="title" style="clear: both"><a id="conventions"></a>Conventions Used in this Book</h2> 85 </div> 86 </div> 87 <div></div> 88 </div> 89 <p> 90 The following typographical conventions are used within in this manual: 91 </p> 92 <p> 93 Structure names are represented in <tt class="classname">monospaced font</tt>, as are <tt class="methodname">method 94 names</tt>. For example: "<tt class="methodname">DB->open()</tt> is a method 95 on a <tt class="classname">DB</tt> handle." 96 </p> 97 <p> 98 Variable or non-literal text is presented in <span class="emphasis"><em>italics</em></span>. For example: "Go to your 99 <span class="emphasis"><em>DB_INSTALL</em></span> directory." 100 </p> 101 <p> 102 Program examples are displayed in a <tt class="classname">monospaced font</tt> on a shaded background. 103 For example: 104 </p> 105 <pre class="programlisting">/* File: gettingstarted_common.h */ 106typedef struct stock_dbs { 107 DB *inventory_dbp; /* Database containing inventory information */ 108 DB *vendor_dbp; /* Database containing vendor information */ 109 110 char *db_home_dir; /* Directory containing the database files */ 111 char *inventory_db_name; /* Name of the inventory database */ 112 char *vendor_db_name; /* Name of the vendor database */ 113} STOCK_DBS; </pre> 114 <p> 115 In some situations, programming examples are updated from one chapter to the next. When 116 this occurs, the new code is presented in <b class="userinput"><tt>monospaced bold</tt></b> font.
