The invention relates to a method for organising a relational database for a computer architecture comprising at least one processor and a memory, characterised in that it involves stages consisting in producing a hierarchical expansion table, forming a thesaurus on each of columns, producing a radical tree for a set of line indexes on which said word appears for each word of each thesaurus and in storing the sequence of said values for each primary key by permutating the set of said values in order to find data.

La présente invention se rapporte à un procédé d'organisation d'une base de données relationnelle destiné à être mis en .oelig.uvre sur une architecture informatique comprenant au moins un processeur et de la mémoire, caractérisé en ce qu'il comporte les étapes consistant à élaborer une table d'expansion hiérarchique ; créer un thésaurus sur chacune des colonnes ; .bullet. pour chacun des mots de chacun des thésaurus, créer l'arbre des radicaux de l'ensemble des indices de lignes sur lesquelles ledit mot apparaît ; .bullet. pour chacune des clés primaires, stocker la suite de ces valeurs en mettant en .oelig.uvre une permutation sur l'ensemble de ces valeurs dans le but de retrouver une donnée.
