Description of the illustration adxdb018.eps

The figure illustrates the difference between RESOURCE_VIEW and PATH_VIEW. In a typical tree, RESOURCE_VIEW has only one path. Because many Internet applications need only one URL to access a resource, RESOURCE_VIEW is widely applicable. With PATH_VIEW, you create a link to access the target resource node, which provides two access paths to the target node for faster access.

RESOURCE_VIEW Example:

select path(1) from RESOURCE_VIEW where under_path(res,'/sys',1);

displays one path to the resource:

/home/corp/po_westcoast

PATH_VIEW Example:

select path from PATH_VIEW;

displays all paths to the resource:

/home/corp/po_westcoast 
/home/role/po_eastcoast
