Abstract: A computer-implemented information system involves data objects stored in the database with characteristics of such data objects defined at a design time. The system is able to associate customized data object events with at least some of the data objects subsequent to the design time to define subscriber objects. Data objects which are publisher objects are determined based on the events. In one implementation, the information system includes a messaging manager, with a message broker and an event controller associated therewith.

Abstract: In one embodiment the present invention includes a plurality of processes for storing data. The processes may include identifiers for specifying other processes representing other resources. In one embodiment, the processes store link types for specifying a relationship type between the resource represented by the process and other resources represented by other processes. Processes may represent data elements and the links may represent relationships between the data. Queries may be conducted across the data in parallel by sending messages to the processes. In one embodiment, the processes represent RDF subjects and RDF objects, and the links represent RDF predicates. Queries for RDF data satisfying predefined criteria or relationships can be performed in parallel by executing processes at the same time on different threads on one or more CPUs.
