The invention relates to culturally sensitive sorting of records. The invention provides a method and a computer system for sorting a set of keyed records based on a preferred locale specification having collation information of a culture. The method is performed on a computer system operatively coupled to a computer readable memory storing the set of keyed records. The steps include reading a locale token associated with the set of records, the locale token identifying a preferred locale object having collation information, using the preferred locale object to locate and read the collation information, creating a culturally correct collation key for each data key associated with the each record, and using the created culturally correct collation keys to sort the set of records into a culturally correct sorted order.

The present invention provides system managed buffering within a data storage system. In a preferred embodiment, when a user or application program makes an I/O request, the data storage system passes control to system managed buffering. System managed buffering queries the user or application request to see how the user/application will be reading or writing the data. Based on the intended use, the system and method disclosed herein allocates the buffers for the user or application based on the intended access to the data, the file size and optionally, the storage device attributes. Also in accordance with the objects of the present invention, the system and method provide for continuous improvement over the previous buffer allocations.
