<p>The invention relates to a search engine ( 2 ) implemented by a decision application server ( 1 ) acting on a relational database ( 6 ) that contains a set of target records. The engine ( 2 ) is activated by queries for selecting records based on given criteria and comprises means ( 8 ) for preconditioning the database ( 6 ) supplying a preconditioned encoded table ( 10 ), periodically updated at the same time as the relational database ( 6 ) itself, to a machine with vectorial capabilities ( 9 ) in order for it to be processed. It also comprises means ( 7 ) for extracting target records, activated by the queries based on the result of the processing of the table ( 10 ) installed in the machine with vectorial capabilities ( 9 ), from the relational database ( 6 ). It particularly applies to data warehousing systems.</p> |
