        <resources>
            <db>
                <table_prefix><![CDATA[]]></table_prefix>
            </db>
            <default_setup>
                <connection>
                    <host><![CDATA[localhost]]></host>
                    <username><![CDATA[root]]></username>
                    <password><![CDATA[]]></password>
                    <dbname><![CDATA[hello]]></dbname>
                    <active>1</active>
                </connection>
            </default_setup>

            <vip_space_read>
                <connection>
                    <host><![CDATA[localhost]]></host>
                    <username><![CDATA[root]]></username>
                    <password><![CDATA[]]></password>
                    <dbname><![CDATA[hello_dev_test]]></dbname>
                    <model>mysql4</model>
                    <initStatements>SET NAMES utf8</initStatements>
                    <type>pdo_mysql</type>
                    <active>1</active>
                </connection>
            </vip_space_read>
        </resources>
        <session_save><![CDATA[files]]></session_save>
    </global>
    <admin>
        <routers>
            <adminhtml>
                <args>
                    <frontName><![CDATA[hello_admin]]></frontName>
                </args>
            </adminhtml>
        </routers>
    </admin>
</config>

2. 在需要使用的不同数据库的model resource中，重写 _setResource 方法，例如

class Hello_Vip_Model_Entity_Vip_Adapter extends Mage_Core_Model_Mysql4_Abstract
{
    protected $_logFile = 'vip.adapter.log';

    protected function _construct()
    {
        $this->_setResource(array('read' =>'vip_space_read', 'write' =>'vip_space_read'));
    }

经过以上两步，就能在某个model中使用不同的数据库
