<h1 align=center>Storing records</h1>
<p>The <a href="../../api_c/db_put.html">DB->put</a> function is the standard interface for storing records into
the database. In general, <a href="../../api_c/db_put.html">DB->put</a> takes a key and stores the
associated data into the database.
<p>There are a few flags that you can set to customize storage:
<p><dl compact>
<p><dt><a href="../../api_c/db_put.html#DB_APPEND">DB_APPEND</a><dd>Simply append the data to the end of the database, treating the database
much like a simple log. This flag is only valid for the Queue and Recno
access methods.
<p><dt><a href="../../api_c/db_put.html#DB_NOOVERWRITE">DB_NOOVERWRITE</a><dd>Only store the data item if the key does not already appear in the database.
</dl>
<p>If the database has been configured to support duplicate records, the
<a href="../../api_c/db_put.html">DB->put</a> function will add the new data value at the end of the duplicate
set. If the database supports sorted duplicates, the new data value is
inserted at the correct sorted location.
