Abstract
A method for accessing metadata includes: receiving an authentication information query request from a query engine, and sending the authentication information query request to a global database server; receiving authentication information from the global database server; sending the authentication information to the query engine so that the query engine determines, according to privilege authentication result of the authentication information, whether to access table information. A corresponding server and system are also disclosed. By storing authentication information in global database server and storing table information in one or more segment database servers, distributed storage of metadata is achieved; the metadata accessing server obtains from the global server the authentication information queried by the query engine and obtains from the segment database server the table information queried by the query engine, which reduces metadata access time and increases the speed of sharing and exchange of information in a distributed data warehouse.
