Metadata management strategy based on DBMS

The mass storage systems generally exploit the hierarchy architecture or hashing scheme to manage the metadata,which requires more time and memory consumption for some operations,such as modifying metadata and querying directory,thus,it seriously affects the performance of the system.This paper introduced the two-dimension table to preserve the metadata and proposed a new management strategy for metadata which based on DBMS.At the same time,analyzed the time and memory consumption and the flexibility of managing the metadata,when using the new strategy to manage the metadata information in the mass storage system.Finally,validated that the new strategy could reduce the time and memory consumption for query and update effectively,and could manage the metadata efficiently and flexibly.So improved the performance of the mass storage system effectively.
