Abstract: A Database Management System having a Collation Engine with improved methods for sorting information with National Language Support (NLS) is described. The Collation Engine includes an improved method for comparing text strings with a culturally predictable result. In an exemplary embodiment, the Collation Engine includes a Collation Table storing primary, secondary, and tertiary weightings. The weightings are employed, in a method of the present invention, for accounting for locale-dependent factors or rules other than those taken into account by conventional primary and secondary weightings. Additional rules include, for instance, local-specific sorting rules specifying that the case of a character be taken into consideration, or that the expansion of an expanding character (e.g., "" which expands to "AE") be taken into consideration.
