    • An improved data access layer (DAL) architecture enables database connection pooling or multiplexing across machine boundaries. Drivers installed at web servers communicate with servers in a DAL. The DAL servers present a virtual database to the web servers, and the DAL servers in turn open connections to a set of physical databases. DAL servers are able to recycle connections that are no longer needed, or to move available connections from one DAL server to another, so as to provide improved efficiency in connection management, burst management, and peak load management. Scalability is thereby improved, and more efficient use of system resources is facilitated.
    • 改进的数据访问层(DAL)架构使数据库连接池或跨机器边界的多路复用。 安装在Web服务器上的驱动程序与DAL中的服务器通信。 DAL服务器将虚拟数据库呈现给Web服务器,DAL服务器依次打开与一组物理数据库的连接。 DAL服务器能够回收不再需要的连接,或者将可用连接从一个DAL服务器移动到另一个,从而提高连接管理,突发管理和峰值负载管理的效率。 从而提高可扩展性,并且更有效地利用系统资源。
