Embodiment Construction

[0028] Embodiments of the present invention provide a tree structure data query method, device, device, and storage medium, which are used to obtain the coding information of each organization node and generate organization information by hierarchically associating the tree structure data in the data warehouse hive. Hierarchical wide tables improve the efficiency of hierarchical relational query of multi-layer organizations in hive.

Abstract

The invention relates to the technical field of big data, and discloses a tree structure data query method, device and equipment and a storage medium, which are used for improving the query efficiencyof tree structure data. The tree structure data query method comprises the steps of receiving a data query request to obtain encoding information of a target institution node and a hierarchical valueof a to-be-queried institution node; reading a preset mechanism dimension table according to the encoding information to obtain a hierarchical value of the target mechanism node; querying a preset mechanism level wide table according to the level value of the to-be-queried mechanism node, the coded information and the level value of the target mechanism node to obtain to-be-verified coded information; when the to-be-verified coded information is not the null value, sending the to-be-verified coded information to the terminal; and when the to-be-verified coded information is a null value, recursively querying the preset mechanism dimension table to obtain coded information of the to-be-queried mechanism node, and recording the coded information in a preset mechanism level wide table. The invention also relates to a blockchain technology, and the target institution node can be stored in the blockchain node.

Description

technical field [0001] The invention relates to the field of tree table query of big data technology, in particular to a tree structure data query method, device, equipment and storage medium. Background technique [0002] With the increase of data diversity, the number of tables is also increasing. The metadata management platform is an important management tool in the field of big data. Through the metadata management platform, the field name, annotation information, and blood relationship of the table can be queried according to the table. and queries for user-defined functions. [0003] However, in actual development and use, the level line of an organization is obtained through the relationship between the upper and lower levels of the organization. Usually, the table stores the coding information of each organization node, the organization level and the parent organization node, and the coding information of each organization node It can only be found through layers o...
