  • Lightweight data replication
    Patent number: 6847971
    Abstract: A lightweight row transfer protocol is described that can be easily handled by thin clients, such as JAVA™ applications using CORBA. The lightweight row transfer protocol serves to reduce bandwidth requirements by applying compression techniques to reduce the number of column lengths in a “result set” of rows that are transmitted from one computer to another.

  • Data replication security
    Patent number: 6792540
    Abstract: An approach is described for improved security during data replication, in which a refresh program runs in the security domain of a trusted user. The refresh program first checks to see if the requesting user actually owns the snapshot before reconciling differences in refreshing a snapshot. Untrusted users are granted only connect privileges and the ability to run a refresh program.

  • Data replication for front office automation
    Patent number: 6532479
    Abstract: Replication for front office automation involves the use of snapshots that are instantiated on laptops, in which refreshing the snapshots is driven from a master site with a high-performance protocol. All of the necessary snapshot metadata for performing the snapshot refreshes is stored at the master site, so that the laptop only needs to send a single refresh request. In response to the refresh request, the master site reconciles the differences between the master tables and the laptop's snapshots and transmits the differences to the laptop, reducing the necessary network traffic for updating a snapshot to a single round trip.
