Question:

what are the differences of these?

will http://www.yoursite.com/dev/build work on the second class?

```
class Player extends DataObject 
{
    private static $db = [
        'PlayerNumber' => 'Int',
        'FirstName' => 'Varchar(255)',
        'LastName' => 'Text',
        'Birthday' => 'Date'
    ];
}


class Player extends Page
{
    private static $db = [
        'PlayerNumber' => 'Int',
        'FirstName' => 'Varchar(255)',
        'LastName' => 'Text',
        'Birthday' => 'Date'
    ];
}

Page is actually a DataObject, but an extension of SiteTree.

Your second example will create a new PageType called Player.

The first example will be a DataObject only and won’t inherit all of the properties that come with SiteTree (pages).

Silverstripe CMS Lessons » Controller Actions / DataObjects as Pages » Silverstripe CMS
DataObjects are more primitive than Page objects. They contain none of the functionality for rendering a template, they have no Link() method, no meta tags, no controllers, etc. In short, they’re not meant to be rendered as full pages.

Hey Jerome, the Silverstripe docs are getting pretty good nowadays. A lot of the answers to your questions can be found in there.
