Design and implementation of large-screen full-screen system for visualization of recruitment data in Hangzhou, Zhejiang (based on Django framework)

1. Research background and significance

With the rapid development of the Internet and information technology, data has shown explosive growth. How to extract valuable information from massive data to provide scientific basis for corporate and individual decision-making has become a hot issue in current research. Recruitment data is an important source of information in the business operation process, and its visual analysis has important practical significance.

This research aims to design and implement a large-screen full-screen recruitment data visualization system based on the Django framework to meet the needs of enterprises for real-time viewing and analysis of recruitment data. Through visualization, key indicators in the recruitment process are displayed on the big screen in the form of charts, images, etc., helping companies quickly grasp the recruitment situation, optimize recruitment strategies, and improve recruitment efficiency.

2. Research status at home and abroad

At present, there are many studies and practices on data visualization at home and abroad. Abroad, data visualization tools such as Tableau and Power BI have been widely used in the field of enterprise data analysis. Domestically, cloud computing vendors such as Alibaba Cloud and Tencent Cloud have also launched their own data visualization products. However, in the field of recruitment data visualization, although some online recruitment platforms provide simple data statistics functions, there is still a lack of visual analysis system for internal recruitment data of enterprises.

3. Research ideas and methods

This study uses the Django framework as the back-end technical support. By crawling the recruitment information on the recruitment website, the data is cleaned and processed and stored in the database. The front-end uses HTML, CSS, JavaScript and other technologies to realize the visual display of data. The specific research methods are as follows:

1. Data crawling: Use the Scrapy framework to crawl recruitment information on recruitment websites, including job title, salary, working location, release time, etc.
2. Data cleaning and processing: Clean and process the crawled data, remove duplicate information, filter irrelevant data, etc.
3. Database design: Design the database table structure and store the cleaned data in the database.
4. Back-end development: Use the Django framework to build a back-end server to implement operations such as adding, deleting, modifying, and checking data.
5. Front-end development: Use HTML, CSS, JavaScript and other technologies to achieve visual display of data, including charts, images and other forms.
6. System testing and optimization: Test the system and optimize performance bottlenecks.

4. Research content and innovation points

The main contents of this study include:

1. Recruitment data crawling and cleaning: Crawling and cleaning recruitment information on recruitment websites to provide basic data support for subsequent data analysis and visualization.
2. Database design and implementation: Design the database table structure according to the characteristics of recruitment data to realize data storage and management.
3. Analysis and implementation of back-end functional requirements: Analyze the needs of enterprises for visualization of recruitment data, and implement operations such as addition, deletion, modification, and query of back-end data.
4. Analysis and implementation of front-end functional requirements: Design the interface layout and interaction method of the large visual screen to achieve graphical display and full-screen display of data.
5. System testing and optimization: Conduct comprehensive testing of the system to identify and resolve potential problems and performance bottlenecks.

The innovations of this study are mainly reflected in the following aspects:

1. In response to the visual analysis needs of internal recruitment data of the enterprise, a large-screen full-screen system for visualizing recruitment data based on the Django framework was designed and implemented.
2. A development model that separates the front and back ends is adopted to improve the scalability and maintainability of the system.
