  • Data access layer
    Patent number: 8589365
    Abstract: 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.
    Type: Grant
    Filed: July 30, 2012
    Date of Patent: November 19, 2013
    Assignee: Wal-Mart Stores, Inc.
