	description=" The Store class encapsulates a client side cache of Record objects which provide input data for Components such as the GridPanel, the ComboBox, or the DataView. A Store object uses its configured implementation of DataProxy to access a data object unless you call loadData directly and pass in your data. A Store object has no knowledge of the format of the data returned by the Proxy. A Store object uses its configured implementation of DataReader to create Record instances from the data object. These Records are cached and made available through accessor functions." %>
