destoon® B2B网站管理系统(以下简称destoon)由西安嘉客信息科技有限责任公司独立研发并推出，对其拥有完全知识产权，中国国家版权局计算机软件著作权登记号：2009SR037570。系统使用当前流行的PHP语言开发，以MySQL为数据库，采用B/S架构，MVC模式开发。融入了模型化、模板、缓存、AJAX、SEO等前沿技术。与同类产品相比，系统功能更加强大、使用更加简单、运行更加稳定、安全性更强，效率更高，用户体验更好。系统开源发布，便于二次开发、功能整合、个性修改。代码首先包含common.inc.php文件在common.inc.php文件中，首先定义常量。define('IN_DESTOON', true);define('IN_ADMIN', defined('DT_ADMIN') ?
