Abstract: A three-phase database crash recovery mechanism is detailed including a forward phase, a backward phase, and a third, so-called “sideward” phase for recovery of transactions which were interrupted at the time of the crash, using Global Transaction IDs to track the status of the transactions at the coordinating and at the participating nodes. Depending upon the status of the transaction at the time of the crash, either a query message to the coordinating node or a vote message to the participating nodes is generated and processed, thereby allowing most interrupted transactions to be completed.

Abstract: A system and method for creating a knowledge base continuously developed through a method of repetitiously connecting various sources of locally and remotely located sources of data. The various sources of data can include reports, articles, books, audio recording, multi-media or computer data. The system uses a systematic approach of selecting a search criteria, selecting a set of search objects, identifying connections (relationships) between the search criteria and the search objects, creating an attribute (description of the relationship) and storage of the connection and its attribute. By following this approach additional connections can be made between already connected objects to exhaustively collect all possible relationships between objects. Through the use of unique identifiers the connections are made between systems located across networks.
