Abstract: A system for adaptive cloud-based routing, comprising a cloud-based work router that may receive work tasks from clients and route them to resources based on known configuration information or status information from clients and resources, and a configuration server for establishing configuration parameters, and a method for providing adaptive routing behavior.

Abstract: A database system supporting persistent queries, comprising a client software application, a persistent query service, and a plurality of network-attached data sources. On receiving a request to create a persistent query from the client software application, the persistent query service: creates a query virtual table; parses the persistent query; creates a plurality of intermediate virtual tables; establishes listeners for the query virtual table; creates a plurality of data source virtual tables; causes the plurality of data source virtual tables to retrieve initial data from data sources; and propagates data via intermediate virtual tables to the persistent query virtual table. On detection of a data change in a data source, the associated data source virtual table causes the data change to propagate via intermediate virtual tables to the persistent query virtual table, and the client software application executes client code of at least one listener.

Abstract: A system and method for integrating one or more external systems, where the integration is achieved through the collaboration of an engine and one or more adapters. The engine can be configured with a set of rules that defines how messages are distributed among the adapters, and is responsible for enforcing those rules. Each adapter is associated with an external system. Each adapter is responsible for translating messages received from the associated external system into a common messaging protocol and for transmitting the translated messages to the engine. In addition, each adapter is responsible for translating messages in the common messaging protocol received from the engine and for transmitting the translated messages to the associated external system. Engines and adapters may be distributed among several computers.
