Patent

CA 2371731

The invention provides a means of disambiguation that is rule-driven. The user is relieved of understanding the details of how the disambiguation is being done. In some cases two tables can be joined by more than one association or criteria on the row values of selected columns, to produce what is effectively a wider table, and this may result in an ambiguity of which join should be used. The system described in this invention makes use of rules such that the user is not faced with a decision as to which rule to use but rather system makes the choice based on clear transformation rules which relate to folders or groups of the tables and their associations
