<h1>CRUD<a class="headerlink" href="#crud" title="Permalink to this headline">¶</a></h1>
<p>CRUD stands for <em>create</em>, <em>read</em>, <em>update</em>, and
<em>delete</em>, which are the four core database operations used in
database driven application development. The <a class="reference internal" href="#crud-operations"><em>CRUD Operations</em></a>
section provides introduction to each class of operation along with
complete examples of each operation. The documents in the
<a class="reference internal" href="#crud-read-and-write"><em>Read and Write Operations</em></a> section provide a higher level overview of
the behavior and available functionality of these operations.</p>

<p>The <a class="reference internal" href="core/read-operations.html"><em>Read Operations</em></a> and <a class="reference internal" href="core/write-operations.html"><em>Write Operations</em></a>
documents provide higher level introductions and description of the
behavior and operations of read and write operations for MongoDB
deployments. The <a class="reference internal" href="core/document.html"><em>BSON Documents</em></a> provides an overview of
<a class="reference internal" href="reference/glossary.html#term-document"><em class="xref std std-term">documents</em></a> and document-orientation in MongoDB.</p>
