SYSTEM AND METHOD FOR REWRITING QUERIES IN DISTRIBUTED DIRECTORY SERVICES

摘要

A distributed directory service includes data sources (DS#1 through DS#5), index servers (IS#1, IS#2 and IS#3) and a client. The data sources generate an index of their data as well as a listing of their schema and a mapping from their schema to their index server's schema. This information is then transmitted to the index server for each data source, which repeats the process by providing an index and mapping information to its index server(s), if any.
