/** implements a component which allows browsing the data sources registered on the system.

    <p>
    This service implements a user interface for browsing data sources registered on the
    <type scope="com::sun::star::sdb">
    DatabaseContext
    </type> 
    instance of the system.
    </p>

    <p>
    It is possible to navigate through all the data sources, it's queries and it's tables.
    The queries/tables can be displayed in a grid-like view, where functionality for searching,
    sorting, filtering, and such is provided.
    </p>

    <p>
    Usually, you won't instantiate this service directly, instead you use the dispatch mechanisms
    of the application framework to load the URL <b>.component:DB/DataSourceBrowser</b> into an arbitrary
    frame. This should involve a 
    <type scope="com::sun::star::sdb">
    ContentLoader
    </type> 
    service, which creates and initializes
    the browser.
    </p>

    <p>
    Some aspects of the browser can be controlled from outside, e.g.,
    it is possible to dispatch a sort or filter
    request, if a table or query is being displayed.
    </p>

    <p
    >The communication between the browser and external instances works in two ways.
    <br/>
    The way <em>in</em> is provided by the 
    <type scope="com::sun::star::frame">XDispatchProvider</type>
    interface the service exports (Please see below for more details on this).
    <br/>
    The way <em>out</em> works in another way. There are several URLs which an external
    instance can provide dispatches for (usually by implementing a 
    <type scope="com::sun::star::frame">XDispatchProviderInterceptor</type>
    for the parent frame of the browser), thus indicating that the browser should provide special functionality.
    <br/>
    In this case, the browser displays and maintains some additional slots (to be more concrete: toolbox items), which,
    upon triggering, call the 
    <member scope="com::sun::star::frame">XDispatch::dispatch()</member> method of the object
    provided by the external instance.
    </p>

    <p>
        In particular, the supported URLs for communicating to an external instance are:
        <ul>
            <li><b>.uno:DataSourceBrowser/InsertColumns</b>
            <br/>
            Available whenever an external instance provides a dispatcher (
            <type scope="com::sun::star::frame">XDispatch</type>)
            for this URL.
            <br/>
            Enabled, if at least one row in the grid view of a table or query is selected.
            <br/>
            It is the task of the external instance to provide functionality for this URL, but usually it is used
            to implement some kind of "Data To Text" functionality.
            <br/>
            </li>
            <li><b>.uno:DataSourceBrowser/InsertContent</b>
            <br/>
            Available whenever an external instance provides a dispatcher(
            <type scope="com::sun::star::frame">XDispatch</type>
            ) for this URL.
            <br/>
            Enabled, if at least one row in the grid view of a table or query is selected.
            <br/>
            It is the task of the external instance to provide functionality for this URL, but usually it is used
            to implement some kind of "Data To Fields" functionality.
            <br/>
            </li>
            <li><b>.uno:DataSourceBrowser/FormLetter</b>
            <br/>
            Available whenever an external instance provides a dispatcher (
            <type scope="com::sun::star::frame">XDispatch</type>) for this URL.
            <br/>
            It is the task of the external instance to provide functionality for this URL, but usually it is used
            to implement some kind of "Form Letter" functionality.
            <br/>
            </li>
        </ul>
    </p>
    <p>For all kinds of URLs, the parameters supplied during dispatching build up a <type>DataAccessDescriptor</type>,
    where the following properties are present:
    <ul>
        <li><member>DataAccessDescriptor::DataSourceName</member></li>
        <li><member>DataAccessDescriptor::Command</member></li>
        <li><member>DataAccessDescriptor::CommandType</member></li>
        <li><em>optional</em> <member>DataAccessDescriptor::Selection</member></li>
        <li><em>optional</em> <member>DataAccessDescriptor::BookmarkSelection</member></li>
        <li><em>optional</em> <member>DataAccessDescriptor::ResultSet</member></li>
    </ul>
    </p>
    <p>The default for <member>DataAccessDescriptor::Selection</member> is to contain bookmarks, if not specified
    otherwise by <member>DataAccessDescriptor::BookmarkSelection</member>.</pr>
