Abstract

The invention discloses a data query method and device for a data tree. The method comprises the following steps: receiving a query request for a target node of a data tree, wherein the query request comprises a query condition; according to the first class of the target nodes and the second class of the target objects indicated by the query condition, cutting the data tree to obtain a relation chain from the target nodes to the target objects; acquiring all relations in the relation chain, and obtaining a relation list, wherein the relations are logic relations between two connected points in the data tree; and according to the relationship list, searching the target object meeting the query condition. The technical problem of low efficiency due to the fact that the whole attribute structure often needs to be traversed and the data meeting the requirement is queried when the attribute structure data is queried in the related technology is solved.

Description

technical field [0001] The invention relates to the field of data query, in particular to a data tree data query method and device. Background technique [0002] In the model-based management information system, the data is presented through a tree structure, such as figure 1 as shown, figure 1 It is a schematic diagram of a data tree structure in the prior art. In the management information system, the user has a query requirement, and wants to check whether there is another type of object that meets the criteria under the tree structure of a certain type of object, for example, query whether a certain product contains a document whose name is equal to "Manual" . In the prior art, this kind of query is often complicated, and the entire attribute structure needs to be traversed to query the data that meets the requirements, which has the problem of low efficiency. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention ...
