Embodiment Construction

[0048] In the embodiment of the present invention, the entire tree-type data is regarded as a collection, the parent node in the tree-type data is regarded as a parent collection, the child nodes are regarded as sub-collections in the parent collection, and the child nodes under the child nodes are regarded as smaller sub-collections in the sub-collection , thereby eliminating the limitation of the tree data hierarchy and improving the efficiency of tree data management.

[0049] Such as image 3 As shown, an embodiment of the present invention proposes a tree data processing method, including:

[0050] Step S101, obtaining the parent node and child node of the tree data;

[0051] As mentioned above, the tree data has a parent-child relationship, which includes a parent node and several child nodes, wherein the child nodes include child nodes directly under the parent node and child nodes under the child nodes belonging to the parent node, and so on.

[0052] Such as Figur...

Abstract

The invention relates to a processing method and a device of tree type data. The method includes obtaining a father node and child nodes of the tree type data; displaying the structure of the tree type data in a set mode according to the subjection relations between the father node and the child nodes and between the child nodes; and starting from one side of the boundary of the set at the outermost layer to number boundary points of each set sequentially, wherein the numbers at two sides of the boundary of each set are used for limiting the range of the set. According to the method and the device, the problem of insufficient structural management of the tree type data in the prior art is solved, the management of the tree type data is more efficient, the query performance is higher, simultaneously, limit of the tree type data hierarchy is eliminated, and the method and the device are particularly suitable for the management of mass tree type data such as a family tree, a gene spectrum and a bill of material (BOM).

Description

technical field [0001] The invention relates to the technical field of tree data management, in particular to a method and device for processing tree data in a set nesting manner. Background technique [0002] Tree data refers to a data set in which each item of data has only one parent node and zero or more child nodes (except the root node). [0003] Most of the existing tree data are managed through relational databases. However, since the tables in the relational database have no tree relationship, they can only present simple flat data, while the tree data has a parent-child relationship, so the tables in the relational database cannot well represent the tree of the tree data type characteristics. [0004] At present, there are two types of adjacency list representation structure and hierarchical code representation structure for tree data management, among which: [0005] Such as figure 1 As shown, in the adjacency list representation structure, each item in the da...
