ArrayReader：

Ext.onReady(function(){
			var store = new Ext.data.Store({
				data:[['sam'],['jack'],['tom']],
				reader:new Ext.data.ArrayReader({},Ext.data.Record.create(['name']))
			});
			
			alert(store.getCount());
			alert(store.getAt(0).get('name'));
			alert(store.getAt(1).get('name'));
			alert(store.getAt(2).get('name'));
		});

JsonReader：

Ext.onReady(function(){
			var store = new Ext.data.Store({
				data:[{name:'sam'},{name:'jack'},{name:'tom'}],
				reader:new Ext.data.JsonReader({},Ext.data.Record.create(['name']))
			});
			
			alert(store.getCount());
			alert(store.getAt(0).get('name'));
			alert(store.getAt(1).get('name'));
			alert(store.getAt(2).get('name'));
		});

XmlReader：

Ext.onReady(function(){
  			var xml = new XML('<peoples><people><name>sam</name></people><people><name>jack</name></people><people><name>tom</name></people></peoples>');
			var store = new Ext.data.Store({
				proxy:Ext.data.MemoryProxy(xml.getValue()),
				reader:new Ext.data.XmlReader({record:'people'},Ext.data.Record.create(['name'])),
				listeners:{
					load:function(){
						alert(store.getCount());
						alert(store.getAt(0).get('name'));
						alert(store.getAt(1).get('name'));
						alert(store.getAt(2).get('name'));
					}
