数据模型
基本数据模型：
使用<mx:Model>标签和嵌套的xml结构实现
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
   backgroundColor="#FFFFFF">
  <mx:Model id="contactmodel">
    <contact>
      <fname>Rich</fname>
      <lname>Tretola</lname>
      <address>101 Skye St.</address>
      <city>Anytown</city>
      <state>NY</state>
      <zip>11111</zip>
      <phone>5165559999</phone>
      <email>proflex2@gmail.com</email>
    </contact>
  </mx:Model>
  <mx:Panel title="Contact Info" width="200" height="170">
    <mx:Label text="{contactmodel.fname} {contactmodel.lname}" />
    <mx:Label text="{contactmodel.address}" />
    <mx:Label text="{contactmodel.city} {contactmodel.state}, {contactmodel.zip}" />
    <mx:Label text="{contactmodel.phone}" />
    <mx:Label text="{contactmodel.email}" />
  </mx:Panel>
</mx:Application>
也可将xml文件提取了出来，
Contace.xml
<?xml version="1.0"?>
<contact>
  <fname>Rich</fname>
  <lname>Tretola</lname>
  <address>101 Skye St.</address>
  <city>Anytown</city>
  <state>NY</state>
  <zip>11111</zip>
  <phone>5165559999</phone>
  <email>proflex2@gmail.com</email>
</contact>

使用<mx:Model>绑定Contact.xml文件
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
   backgroundColor="#FFFFFF">
  <mx:Model source="Contact.xml" id="contactmodel"/>
  <mx:Panel title="Contact Info" width="200" height="170">
    <mx:Label text="{contactmodel.fname} {contactmodel.lname}" />
    <mx:Label text="{contactmodel.address}" />
    <mx:Label text="{contactmodel.city} {contactmodel.state}, {contactmodel.zip}" />
    <mx:Label text="{contactmodel.phone}" />
    <mx:Label text="{contactmodel.email}" />
  </mx:Panel>
</mx:Application>

使用<mx:XML >绑定Contact.xml文件
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
   backgroundColor="#FFFFFF">
  <mx:XML source="Contact.xml" id="contactmodel"/>
  <mx:Panel title="Contact Info" width="200" height="170">
    <mx:Label text="{contactmodel.fname} {contactmodel.lname}" />
    <mx:Label text="{contactmodel.address}" />
    <mx:Label text="{contactmodel.city} {contactmodel.state}, {contactmodel.zip}" />
    <mx:Label text="{contactmodel.phone}" />
    <mx:Label text="{contactmodel.email}" />
  </mx:Panel>
</mx:Application>

将数据模型绑定到自定义组件
包括公共[Bindable]变量contactmodel（Object类型）的VBOX容器
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml">
 <mx:Script>
  <![CDATA[
   [Bindable]
   public var contactmodel:Object;
  ]]>
 </mx:Script>
 <mx:Label text="{contactmodel.fname} {contactmodel.lname}" />
  <mx:Label text="{contactmodel.address}" />
  <mx:Label text="{contactmodel.city} {contactmodel.state}, {contactmodel.zip}" />
  <mx:Label text="{contactmodel.phone}" />
  <mx:Label text="{contactmodel.email}" />
</mx:VBox>
使用<mx:Model>和自定义组件绑定Contact.xml文件
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
   backgroundColor="#FFFFFF" xmlns:comps="*">
  <mx:Model source="Contact.xml" id="contactmodel"/>
  <mx:Panel title="Contact Info" width="200" height="170">
    <comps:Contact contactmodel="{this.contactmodel}" />
  </mx:Panel>
</mx:Application>

绑定两个xml文件
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
   backgroundColor="#FFFFFF" xmlns:comps="*">
  <mx:Model source="Contact.xml" id="contactmodel"/>
  <mx:Model source="Contact2.xml" id="vacationmodel"/>
  <mx:Panel title="Contact Info" width="300" height="170" layout="horizontal">
    <comps:Contact contactmodel="{this.contactmodel}" />
    <mx:Spacer width="20" />
    <comps:Contact contactmodel="{this.vacationmodel}" />
  </mx:Panel>
</mx:Application>
