Each product offers a distinct level of database support. -It is not possible to mix-and-match products, that is, each application -or group of applications must use the same Berkeley DB product. -<p>All three products are included in the single Open Source distribution of -Berkeley DB from Sleepycat Software, and building that distribution -automatically builds all three products. Each product adds services, and -new interfaces, to the product that precedes it in the list. As a result, -developers can download Berkeley DB and build an application that does only -single-user, read-only database access, and later add support for more -users and more complex database access patterns. -<p>Users who distribute Berkeley DB must ensure that they are licensed for the -Berkeley DB interfaces they use. Information on licensing is available directly -from Sleepycat Software. -<h3>Berkeley DB Data Store</h3> -<p>The Berkeley DB Data Store product is an embeddable, high-performance data store. It -supports multiple concurrent threads of control to read information -managed by Berkeley DB. When updates are required, only a single process may -be using the database. That process may be multi-threaded, but only one -thread of control should be allowed to update the database at any time. -The Berkeley DB Data Store does no locking, and so provides no guarantees of correct -behavior if more than one thread of control is updating the database at -a time. -<p>The Berkeley DB Data Store product includes the <a href="../../api_c/db_create.html">db_create</a> interface, the -DB handle methods, and the methods returned by <a href="../../api_c/db_cursor.html">DB->cursor</a>. -<p>The Berkeley DB Data Store is intended for use in single-user or read-only applications -that can guarantee that no more than one thread of control will ever -update the database at any time. -<h3>Berkeley DB Concurrent Data Store</h3> -<p>The Berkeley DB Concurrent Data Store product adds multiple-reader, single writer capabilities to -the Berkeley DB Data Store product, supporting applications that need concurrent updates -and do not want to implement their own locking protocols. The additional -interfaces included with the Berkeley DB Concurrent Data Store product are <a href="../../api_c/env_create.html">db_env_create</a>, the -<a href="../../api_c/env_open.html">DBENV->open</a> method (using the <a href="../../api_c/env_open.html#DB_INIT_CDB">DB_INIT_CDB</a> flag), and the -<a href="../../api_c/env_close.html">DBENV->close</a> method. -<p>Berkeley DB Concurrent Data Store is intended for applications that require occasional write access -to a database that is largely used for reading. -<h3>Berkeley DB Transactional Data Store</h3> -<p>The Berkeley DB Transactional Data Store product adds full transactional support and recoverability -to the Berkeley DB Data Store product. This product includes all of the interfaces -in the Berkeley DB library. -<p>Berkeley DB Transactional Data Store is intended for applications that require industrial-strength -database services, including good performance under high-concurrency -workloads with a mixture of readers and writers, the ability to commit -or roll back multiple changes to the database at a single instant, and -the guarantee that even in the event of a catastrophic system or hardware -failure, any committed database changes will be preserved. -<table><tr><td><br></td><td width="1%"><a href="../../ref/intro/where.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../ref/toc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/simple_tut/intro.html"><img src="../../images/next.gif" alt="Next"></a> -</td></tr></table> -<p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> -</body> -</html> |
