+			+ "IT Mill Toolkit data model provides interface for implementing "
+			+ "buffering in data components. The basic idea is that a component "
+			+ "reading their state from data source can implement "
+			+ "Buffered-interface, for storing the value internally. "
+			+ "Buffering provides transactional access "
+			+ "for setting data: data can be put to a component's buffer and "
+			+ "afterwards committed to or discarded by re-reding it from the data source. "
+			+ "The buffering can be used for creating interactive interfaces "
+			+ "as well as caching the data for performance reasons."
+			+ "<br /><br />Buffered interface contains methods for committing and discarding "
+			+ "changes to an object and support for controlling buffering mode "
+			+ "with read-through and write-through modes. "
+			+ "Read-through mode means that the value read from the buffered "
+			+ "object is constantly up to date with the data source. "
+			+ "Respectively the write-through mode means that all changes to the object are "
+			+ "immediately updated to the data source.";
