<p>
Although closing a database also closes any open cursors, it is
recommended that applications explicitly close all their Cursor
objects before closing the database. The reason why is that when the
cursor is explicitly closed, the memory allocated for it is
reclaimed; however, this does not happen if you close a database
while cursors are still opened.
</p>
<p>
The same rule, for the same reasons, holds true for
<a href="T_BerkeleyDB_Transaction.htm">Transaction</a> objects. Simply make sure you resolve
all your transaction objects before closing your database handle.
</p>
<p>
Because key/data pairs are cached in-memory, applications should
make a point to always either close database handles or sync their
data to disk (using <a href="M_BerkeleyDB_BaseDatabase_Sync.htm">Sync<span class="languageSpecificText"><span class="cs">()</span><span class="cpp">()</span><span class="nu">()</span></span></a> before exiting, to
ensure that any data cached in main memory is reflected in the
underlying file system.
</p>
<p>
When called on a secondary index's primary database, the primary
should be closed only after all secondary indices referencing
it have been closed.
</p>
<p>
When multiple threads use the object concurrently, only a
single thread may call the Close method.
</p>
<p>
The object may not be accessed again after Close is called,
regardless of its outcome.
