Problems solved by technology

[0023] In view of the above-mentioned prior art, the purpose of the present invention is to provide a general tree structure storage and analysis method, which solves the problems of huge calculation, complex storage code and complex logic in the prior art due to the use of recursive method to analyze tree structure data. Technical problems such as the tree structure of the data is not intuitive enough

Embodiment 1

[0064] The table structure of the present invention is designed as {id, name, treeCode}. First put figure 1 The data in is organized, and the storage format is shown in Table 3.

[0065]

[0066] Table 3 tree coding stores part of the regional information

[0067] In this table structure, the process of CRUD is as follows:

[0068] To add a node, to add a new node in the table, such as Xindu District under Chengdu City, Sichuan Province, you only need to observe the maximum number of the child node under Chengdu City. The maximum number in Table 3 is Jinniu District 020105, so code the Xindu District tree as 020106. Execute the insert statement as follows:

[0069] INSERT INTO tree(name,treeCode)VALUES('Xindu District','020106').

[0070] The data after insertion is Table 4, and the relationship between the data is automatically formed after the data is inserted through the tree coding method, and the newly inserted data has no effect on other data.

Abstract

The invention discloses a general tree structure storage and analysis method. The invention relates to the field of computer applications and solves the problems of huge calculation, complicated storage code, complex logic and data analysis caused by using a recursive method to analyze tree structure data in the prior art. The tree structure is not intuitive enough and other technical problems. It mainly includes cyclically traversing the data list generated by hierarchical associated data through temporary variables, reading the root data of the data list, using the characteristics of the tree nodes in the data list, and combining the temporary data set to construct the threshold condition, and incrementing the tree nodes that meet the threshold condition in order Set the tree code, and then store the tree code corresponding to the current tree node in the data list into the temporary data set. At the end of the loop, a complete tree-shaped temporary data set relative to the data list is obtained; the corresponding root data searches the temporary data set to obtain a tree-shaped The root tree node and all subtree nodes of the structure. The invention has the characteristics of simple and easy to use, maintainability and strong operability.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a general tree structure storage analysis method. Background technique [0002] In the field of application software, a tree structure is often used to represent the relationship of some data, such as the upper and lower departments of the enterprise, product classification, regional information, navigation column structure information, role authority information, resource relationship information, etc. The storage, analysis, and maintenance of these data are very complex. [0003] At present, the storage of tree structure data is mainly based on database storage. There are mainly two implementation methods. [0004] The first implementation method adopts the method of parent node id association to store the tree structure. [0005] Data based on tree structure figure 1 (Take part of the regional information as an example): [0006] This way of storing the tree structure...
