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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, server, and system for accessing metadata","description":"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 serve","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9619503","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
