Welcome to Berkeley DB (DB).
<span>
This document introduces Berkeley DB 11<span class="emphasis"><em>g</em></span> Release 2, which provides DB library version 11.2.5.1.
</span>
</p>
<p>
This document 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>
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>. For example:
<span>"<code class="methodname">Db::open()</code> is a
<code class="classname">Db</code> class method."</span>
</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 <code class="classname">monospaced font</code> on a shaded background.
For example:
</p>
<pre class="programlisting">typedef struct vendor {
char name[MAXFIELD]; // Vendor name
char street[MAXFIELD]; // Street name and number
char city[MAXFIELD]; // City
char state[3]; // Two-digit US state code
char zipcode[6]; // US zipcode
char phone_number[13]; // Vendor phone number
} VENDOR; </pre>
<p>
In some situations, programming examples are updated from one chapter to the next. When
this occurs, the new code is presented in <strong class="userinput"><code>monospaced bold</code></strong> font. For example:
</p>
<pre class="programlisting">typedef struct vendor {
char name[MAXFIELD]; // Vendor name
char street[MAXFIELD]; // Street name and number
char city[MAXFIELD]; // City
char state[3]; // Two-digit US state code
char zipcode[6]; // US zipcode
char phone_number[13]; // Vendor phone number
<strong class="userinput"><code>char sales_rep[MAXFIELD]; // Name of sales representative
char sales_rep_phone[MAXFIELD]; // Sales rep's phone number </code></strong>
} VENDOR; </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.
