Fecha de publicación: 23/12/2010 Fuente: WIPO "swarm" A method of managing a database system that includes a search engine. The database system receives N number of requests from one or more nodes in the database system. The N requests are combined before initiating operations to attend to the requests. The number of operations to attend to the requests is reduced and this reduced number of operations is executed. The search engine comprises a decentralized swarm system that utilizes swarm algorithms. The N requests include N add requests to add to a value in a row stored in the database system. Combining the N requests includes combining the add requests to the value in the row stored in the database system; and executing the reduced number of operations includes executing the operation of adding to the value in the row stored in the database system for the N number of add requests in less than N transactions.
