Abstract

The invention discloses a big data management method, which comprises the steps that a plurality of clouds are arranged in combination with a cloud network architecture, and each cloud is set to be ofa tree topology structure; a plurality of metadata and corresponding metadata attribute values are obtained, wherein the metadata attribute values comprise metadata types and levels; different typesof metadata are stored in different nodes of different clouds according to metadata attribute values in sequence, the metadata type is the same as the node data type of the corresponding stored node,and the metadata hierarchy is the same as the node data hierarchy of the corresponding stored node; an index table of each node is set, wherein the index table is used for querying associated data ofmetadata stored in the current node and a link of the associated data; and after a query operation instruction is received, metadata and associated data of the metadata are queried through the index table.

Description

technical field [0001] This application relates to the technical field of data processing, in particular to methods and systems for big data management. Background technique [0002] City Information Modeling (CIM) is a digital expression and description of various physical objects and spatial states above and below ground, indoor and outdoor in a city. It reflects urban planning, construction, development and operation, and can be used for urban planning decisions, urban construction and urban management. [0003] CIM is a concept with a large span, involving industries including planning, land, transportation, water conservancy, security, civil air defense, environmental protection, cultural relics protection, energy and gas, and all other fields related to smart cities. [0004] At present, there is still a lack of systematic and in-depth research on CIM at home and abroad. According to the viewpoints in the paper "Review of the Development of Urban Information Model Rel...
