    The <app>gda-browser</app> is composed of one or more top level windows, each window relating to a
    single connection (which name is in its title). For any given connection, several windows can be opened
    (use the <guiseq><gui>Window</gui><gui>New window</gui></guiseq> menu or
    the <keyseq><key>Ctrl</key><key>N</key></keyseq> shortcut).

  </figure>

  <p>
    Within each window, several <em>perspectives</em> are available which are adapted to
    different activities:
  </p>
  <list>
    <item><p>the <link xref="schema-browser-perspective">Schema browser perspective</link> to help understand the database's layout</p></item>
    <item><p>the <link xref="query-execution-perspective">Query execution perspective</link> to execute any SQL command</p></item>
    <item><p>the <link xref="data-manager-perspective">Data manager perspective</link> to navigate through the database's contents</p></item>
  </list>
  <p>
    The currently displayed perspective can be changed individually for each window, and, as all perspectives 
    have an action area composed of tabs, tabs can be moved from one window to the other if the source
    and destination window are for the same connection, and display the same perspective (simply drag
    and drop a tab from one window to the other using the tab's label as a handle).
