Method for preconditioning and encoding a data table, and method for the implementation of table requests on a vectoral processor

Search system implemented by a decision application server (1) comprising a relational database (6) containing a set of target records, and a search engine (2) coupled with the decision application server (1), activated by a query for selecting records based on given criteria sent by the decision application server (1), characterized in that the engine (2) includes means (8) for preconditioning data of the base (6) and installing an encoded table (10) corresponding to the base (6) in a machine with vectorial capabilities (9), these means (8) comprising:

• means (13) for reading a data file corresponding to the base;
• means (16) for building a nomenclature (17) for the values of the fields contained in the file;
• means (15) for encoding fields in accordance with the nomenclature (17), taking the nature of the fields and the relations to be implemented in the predicates into account in the query;
• means (21) for analyzing queries sent by the decision application server (1), taking into account the authorized relations, the constraints on the predicates and the nomenclature (17);
• and
• means (22) for encoding the filtered query into a set of vectors containing the values to be found in the fields in accordance with the associated relations, in the form of an input file usable by the machine with vectorial capabilities (9).
