This article will explain in detail what is the structure of the many-to-many relationship between the positions of data elements, and the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

In the graph structure, there is a many-to-many relationship between data elements. Graph structure, also known as reticular structure, is a logical structure formed by many-to-many relations, in which there is no limit to the number of direct antecedents and successors of each element. Usually used to indicate a reticular relationship.

Data structure is the way that computers store and organize data. A data structure is a collection of data elements that have one or more specific relationships with each other. In general, carefully selected data structures can lead to higher operational or storage efficiency. Data structures are often related to efficient retrieval algorithms and indexing techniques.

The logical structure of data refers to the data structure that reflects the logical relationship between data elements, which refers to the relationship between data elements before and after, independent of their storage location in the computer.

Logical structure includes four kinds of basic structures: set structure, linear structure, tree structure, graph structure (or network structure).

Features:

1) set: there is no relationship between the data in the structure except the relationship that "belongs to the same set".

2) Linear structure: there is an one-to-one relationship between the positions of data elements in the structure.

3) Tree structure: there is an one-to-many relationship between the elements in the structure.

4) graphic structure: there is a many-to-many relationship between the data elements in the structure. The graphic structure is also known as the reticular structure.

For example:

1) Collection: a list of students in a class, recorded randomly and disorderly in a notebook.

2) Linear structure: the student list of a class is arranged in the student list in the order of the student number.

3) Tree structure: the relationship between the superior unit of a unit and each subordinate unit.

4) graphic structure: the relationship between bus stops in a city.

What is the structure of the many-to-many relationship between the locations of data elements is shared here. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
