APPARATUS AND METHODS FOR TRANSFORMING RELATIONAL QUERIES INTO MULTI-DIMENSIONAL QUERIES

摘要

A query processor operative to accept queries with respect to data and to formulate responses to the queries and a data system comprising a query analyzer operative to perform breakdown analysis of queries thereby to generate a hierarchical representation of queries and a hierarchical query storage unit operative to store the hierarchical representations. A hierarchical representation processor operative to receive hierarchically represented queries and to formulate all possible multi dimensional roles of its query elements; and a multi dimensional role storage unit operative to store the hierarchical representations with their respective multi dimensional roles. A stochastic query processor operative to accept the hierarchical representations with their respective multi dimensional roles and to eliminate all improbable combinations of query elements (clause components) and multi dimensional roles. Hierarchical representations with their respective multi dimensional roles query processor operative to accept hierarchical representations with their respective multi dimensional roles from a data storage unit and to formulate most probable multidimensional representation of initial relational query.
