<p>A dbstl container is very much like a C++ STL container. </p>
<p>It stores a collection of data items, or key/data pairs. Each container is backed by a Berkeley DB database created in an explicit database environment or an internal private environment; And the database itself can be created explicitly with all kinds of configurations, or by dbstl internally. For each type of container, some specific type of database and/or configurations must be used or specified to the database and its environment. dbstl will check the database and environment conform to the requirement. When users don't have a chance to specify a container's backing database and environment, like in copy constructors, dbstl will create proper databases and/or environment for it. There are two helper functions to make it easier to create/open an environment or database, they are <a class="link" href="stldbstl_global_functionsopen_db.html" title="open_db">dbstl::open_db()</a>
and <a class="link" href="stldbstl_global_functionsopen_env.html" title="open_env">dbstl::open_env()</a>
; </p>
