Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] In order to solve the problems in the prior art that the query operation of the B-number structure in the embedded software is too complicated and the complexity of the data traversal is high, which leads to certain limitations in the efficiency of data traversal and indexing, this application proposes a method based on A multi-fork tree structure for bidirectional linear linked list directory retrieval, electronic equipment and a readable storage medium. Through this multi-fork tree structure ba...

Abstract

The invention provides a multi-way tree structure based on bidirectional linear linked list directory retrieval, electronic equipment and a readable storage medium. The multi-way tree structure comprises a root node, a plurality of data storage nodes and a directory chain table, and in the process of creating the data storage nodes in the multi-way tree structure, the created data storage nodes need to be registered in the directory chain table in advance. Through the multi-way tree structure provided by the invention, the functions of quick traversal, quick addition and deletion, query and modification and the like of the tree nodes can be realized: the traversal of the multi-way tree does not need to carry out preorder or subsequent recursion, and the full-node traversal of the multi-way tree structure can be realized only by traversing the corresponding directory chain table. Meanwhile, the number of the child nodes of the multi-way tree structure is not limited, the number of the child nodes and the subordinate structure can be completely increased and deleted according to actual requirements, flexibility and adaptability are high, and the multi-way tree structure has popularization value.

Description

technical field [0001] The invention relates to the technical field of data storage and data indexing, and in particular discloses a multi-fork tree structure based on bidirectional linear linked list directory retrieval, electronic equipment and a readable storage medium. Background technique [0002] Data is the basic element of information processing, and it is particularly important in the context of the rapid development of the Internet. In different carriers, how to efficiently process, store, query, etc. has become a problem that enterprises and researchers generally have to face and solve. Compared with traditional data, people summarize the characteristics of big data into 5 Vs, namely large data volume (Volume), fast speed (Velocity), multiple types (Variety), difficult identification (Veracity) and low value density (Value) ( CHENGX Q, JINX L, WANGY Z, etc. Survey on big data system and analytic technology [J]. Journal of Software, 2014, 25(9): 1889-1908.) [00...
