A method, computer program, and database system for performing a request on a table associated with an index are disclosed. A database contains a table, an index, and a partition elimination list and accepts a query. A table has one or more rows stored in one or more partitions. The index contains index entries, each of which references a row in a partition, where the row is in the table. The query has a first and a second condition. The partition elimination list is populated with partitions based on the first condition of the query. Only index entries that are identified by the request because of the second condition and that reference partitions that are not eliminated by the partition elimination list are read.

Partition elimination on indexed row IDs

The present invention relates to relates to the efficient and secure transfer of information over a distributed computer network such as the Internet. The system provides parallel communication paths between the source and destination. Each path includes a dedicated route point to eliminate intermediate ISPs. Each source is associated with an archive and each route point is coupled to the archive. Upon receipt of the message at a route point the message is copied to the archive and then transmitted to the destination. Message archival and storage of transmission-related information enables data-mining features not presently available using email or a point-and-click browser. Since two messages are transmitted from the source to the common destination across separate and distinct communication paths, message latency is improved and the chance of lost messages is reduced or even eliminated. A network controller monitors transmission results and dynamically re-configures the network to balance loading across the route points and to avoid failures or other bottlenecks in the system.

System for handling information and information transfers in a computer network

The present invention provides a system and method allowing businesses to send electronic messages, or other information, to conduct business over a digital network such as the Internet. Aspects of the system provide for a secure transfer of messages, tracking, monitoring, archiving, automated responses, statistics gathering and other features. The system provides a plurality of route point processors for routing messages independently of the Internet service providers (ISPs) routers and a unique forking algorithm whereby duplicate messages are generated and transmitted along separate communication backbones. Messages are archived at an intermediate point in the transmission path. The archival system and method provides a distributed archive that stores messages to guarantee message delivery to the destination, assists in message recovery and retains statistical information regarding the routing and delivery of the messages for subsequent access.
