How to design a flexible MySQL table structure to implement paper management functions?

Abstract: This article introduces how to design a flexible MySQL table structure to implement paper management functions. First, the paper management function is summarized and needs analyzed; secondly, the paper table, author table, journal table and relationship table are designed; finally, a basic MySQL table structure example is given.

1. Introduction
   With the continuous progress of scientific research work, paper management has become one of the necessary functions for scientific researchers. As a relational database management system, MySQL can provide powerful data storage and query functions, and is very suitable for implementing a paper management system. This article will introduce how to design a flexible MySQL table structure to implement paper management functions.
2. Overview of paper management functions
   The paper management functions mainly include the following aspects: entry, modification and deletion of paper information; entry, modification and deletion of author information; entry, modification and deletion of journal information; Relationship management between papers and authors.
3. MySQL table structure design
   Based on the demand analysis of the above paper management function, we can design the following MySQL table structure:

(1) Paper table: paper
Fields:

• paper_id: paper ID, primary key
• title: paper title
• abstract: paper abstract
• keywords: keywords
• publication_date: Publication date
• journal_id: Journal ID, foreign key

(2) Author table: author
Field:

• author_id: Author ID, primary key
• name: Author name
• affiliation: Author affiliation

(3) Journal table: journal
Field:

• journal_id: Journal ID, primary key
• name: Journal name
• impact_factor: Impact factor

(4) Relationship table: paper_author
Fields:

• paper_id: paper ID, foreign key
• author_id: author ID, foreign key

4. MySQL table structure example
   The specific MySQL table structure examples are as follows:

(1) Create paper table:
CREATE TABLE paper (

paper_id INT PRIMARY KEY AUTO_INCREMENT,
title VARCHAR(255),
abstract TEXT,
keywords VARCHAR(255),
publication_date DATE,
journal_id INT,
FOREIGN KEY (journal_id) REFERENCES journal(journal_id)

);

（ 2) Create author table:
CREATE TABLE author (

author_id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(255),
affiliation VARCHAR(255)

);

(3) Create journal table:
CREATE TABLE journal (

journal_id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(255),
impact_factor FLOAT

) ;

(4) Create a relational table:
CREATE TABLE paper_author (

paper_id INT,
author_id INT,
FOREIGN KEY (paper_id) REFERENCES paper(paper_id),
FOREIGN KEY (author_id) REFERENCES author(author_id),
PRIMARY KEY (paper_id, author_id)

);

5. Summary
   Design a flexible MySQL table structure To realize the paper management function, you can analyze the functional requirements and design an appropriate table structure to store data. This article gives basic MySQL table structure examples, which can be modified and expanded according to actual needs. Through the rationally designed MySQL table structure, efficient data storage and query can be achieved, and the paper management function can be easily realized.
