We have two goals in this section: 20to familiarize readers with the transactional interfaces of Berkeley DB and 21to provide code building blocks that will be useful for creating 22applications.</p> 23<p>We have not attempted to present this information using a real-world 24application. First, transactional applications are often complex and 25time-consuming to explain. Also, one of our goals is to give you an 26understanding of the wide variety of tools Berkeley DB makes available to you, 27and no single application would use most of the interfaces included in 28the Berkeley DB library. For these reasons, we have chosen to simply present 29the Berkeley DB data structures and programming solutions, using examples that 30differ from page to page. All the examples are included in a standalone 31program you can examine, modify, and run; and from which you will be able 32to extract code blocks for your own applications. Fragments of the 33program will be presented throughout this chapter, and the complete text 34of the <a href="transapp.cs">example program</a> for IEEE/ANSI Std 1003.1 (POSIX) 35standard systems is included in the Berkeley DB distribution.</p> 36<table width="100%"><tr><td><br></td><td align=right><a href="../cam/app.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../transapp/why.html"><img src="../../images/next.gif" alt="Next"></a> 37</td></tr></table> 38<p><font size=1>Copyright (c) 1996,2008 Oracle.
