     \brief The QWebDatabase class provides access to HTML 5 databases created with JavaScript.
 
     The upcoming HTML 5 standard includes support for SQL databases that web sites can create and
-    access on a local computer through JavaScript. QWebDatabase is the C++ interface to these databases.

+    databases.
 
-    For more information refer to the \l{http://www.w3.org/html/wg/html5/#sql}{HTML 5 Draft Standard}.
+    To get access to all databases defined by a security origin, use QWebSecurityOrigin::databases().
+    Each database has an internal name(), as well as a user-friendly name, provided by displayName().
+
+    WebKit uses SQLite to create and access the local SQL databases. The location of the database
+    file in the local file system is returned by fileName(). You can access the database directly
+    through the QtSql database module.
+
+    For each database the web site can define an expectedSize(). The current size of the database
+    in bytes is returned by size().
