DATA INDEX SYNCHRONIZATION METHOD BASED ON REGIONAL PLATFORMS AT ALL LEVELS, AND DATA ACCESS METHOD THEREFOR

摘要

A data index synchronization method based on regional platforms at all levels, and a data access method therefor. A plurality of regional platform servers hierarchically deploy a data routing network; a routing node at the highest level sends, level-by-level from top to bottom, an index synchronization command to routing nodes at lower levels, the routing nodes at the lower levels receive the index synchronization command and generate local index data, and from a routing node at the lowest level, index data is merged level by level from bottom to top; and the routing node at the highest level issues, level by level, the combined index data to routing nodes at all the levels, the routing nodes at all the levels synchronously update the index data, addressing priorities are preset, and the index data is accessed according to the synchronously updated index data and the addressing priorities. By means of all data routing nodes and data markets on all platforms that store data, a storage position of data is identified by using index data; all the data routing nodes are based on an index synchronization mechanism, such that the index data is completely consistent; and a data access channel is established, thereby realizing the retrieval of and the access to service data.
