This document introduces <span>DB, version 4.7. </span> It is intended to provide a rapid introduction to the DB API set and related concepts. The goal of this document is to provide you with an efficient mechanism with which you can evaluate DB against your project's technical requirements. As such, this document is intended for <span>C</span> developers and senior software architects who are looking for an <span> in-process data management solution. </span> No prior experience with Berkeley DB is expected or required. </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></div> </div> <p> The following typographical conventions are used within in this manual: </p> <p> Structure names are represented in <tt class="classname">monospaced font</tt>, as are <tt class="methodname">method names</tt>. For example: "<tt class="methodname">DB->open()</tt> is a method on a <tt class="classname">DB</tt> handle." </p> <p> Variable or non-literal text is presented in <span class="emphasis"><em>italics</em></span>. For example: "Go to your <span class="emphasis"><em>DB_INSTALL</em></span> directory." </p> <p> Program examples are displayed in a <tt class="classname">monospaced font</tt> on a shaded background. For example: </p> <pre class="programlisting">/* File: gettingstarted_common.h */ typedef struct stock_dbs { DB *inventory_dbp; /* Database containing inventory information */ DB *vendor_dbp; /* Database containing vendor information */ char *db_home_dir; /* Directory containing the database files */ char *inventory_db_name; /* Name of the inventory database */ char *vendor_db_name; /* Name of the vendor database */ } STOCK_DBS; </pre> <p> In some situations, programming examples are updated from one chapter to the next. When this occurs, the new code is presented in <b class="userinput"><tt>monospaced bold</tt></b> font. For example: </p> <pre class="programlisting">typedef struct stock_dbs { DB *inventory_dbp; /* Database containing inventory information */ DB *vendor_dbp; /* Database containing vendor information */ <b class="userinput"><tt>DB *itemname_sdbp; /* Index based on the item name index */</tt></b> char *db_home_dir; /* Directory containing the database files */ <b class="userinput"><tt>char *itemname_db_name; /* Itemname secondary database */</tt></b> char *inventory_db_name; /* Name of the inventory database */ char *vendor_db_name; /* Name of the vendor database */ } STOCK_DBS; </pre> <div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"> <h3 class="title">Note</h3> <p> Finally, notes of interest are represented using a note block such as this. </p> </div> <div class="sect2" lang="en" xml:lang="en"> <div class="titlepage"> <div> <div> <h3 class="title"><a id="moreinfo"></a>For More Information</h3> </div> </div> <div></div> </div> <p> Beyond this manual, you may also find the following sources of information useful when building a DB application: </p> <div class="itemizedlist"> <ul type="disc"> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_txn/C/index.html" target="_top"> Getting Started with Transaction Processing for C </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/gsg_db_rep/C/index.html" target="_top"> Berkeley DB Getting Started with Replicated Applications for C </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/ref/toc.html" target="_top"> Berkeley DB Programmer's Reference Guide </a> </p> </li> <li> <p> <a href="http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/frame.html" target="_top"> Berkeley DB C API </a> </p> </li> </ul> </div> </div> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="index.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="index.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="introduction.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Getting Started with Berkeley DB </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Chapter 1.
