MODx provides a really unfriendly way to work with xPDO class. What I means is you need to define XML schma, mysql table and run the script to generate other stuff (model and controller), which is really suck...
Luckly, MIGX DB could help you finish those task easily.
1. Install MIGX package.
2. On the topp menu, find "Extras" => "MIGX".
3. Enter into the MIGX Management, fill in the package and prefix information:
Then click "Create Package" button.
4. Go to "XML Schema" tab, define the schea here.
<?xml version="1.0" encoding="UTF-8"?>

</model>
I just copy the xml from here.
5. Click "Save Schema".
6. Go to "Parse schema" tab to click "Parse schema" button, this will generate model and controller class.php.
7. Go to Create Table tab, click "Create Table" button. This will create mysql table for your according to your xml.
8. Just mock some dump data into the table and test it out. For example, we add two rows of data into modx_sfinder_stores table.
create a snippet called "store".
<?php
$path = MODX_CORE_PATH . 'components/storefinder/';
$result = $modx->addPackage('storefinder',$path .
'model/','modx_'); $storefinder = $modx->newObject('sfStore');
$storefinder->set('name', "XOPO");
$storefinder->set('address', "Somewhere in the world");
$storefinder->set('city', "Helsinki");
$storefinder->set('state', "north Karera");
$storefinder->set('zip', "88888");
$storefinder->set('country', "Finland");
$storefinder->set('phone', "987654");
$storefinder->set('fax', "0332");
$storefinder->set('active', "0");
$storefinder->save();
9. Run the snippet should be able to add data into the database, then we can view the data.
<?php
$path = MODX_CORE_PATH . 'components/storefinder/';
$result = $modx->addPackage('storefinder',$path .
'model/','modx_'); $result= $modx->getCollection('sfStore');
$stores = array(); foreach($result as $res){ echo $res->get('name');
echo $res->get('address');
}
