Abstract
With the rapid development of the agricultural product industry, in-depth analysis of a large amount of agricultural product data has become particularly important. Data analysis has become the core of various industries, and in the field of agricultural products, it plays a more critical role. Understanding consumer preferences for agricultural products, price trends, and popularity of agricultural products is crucial for the operation and provision of better services in the agricultural product field. This study aims to build a Spark based agricultural product price data analysis and prediction system to help the industry better understand consumer behavior, optimize service processes, and provide strong support for business decision-making.
This article first explores the background and significance of the Spark based agricultural product price data analysis and prediction system, and then delves into common technologies such as spider principles, acquisition strategies, and information extraction. Subsequently, the system was developed using Python and built on a MySQL database to achieve the crawling of agricultural product data. Detected and visualized the database query results, and effectively managed the front-end interface of the system. By analyzing the crawling results, present agricultural product price data in a large screen format. Finally, comprehensive testing was conducted to ensure the implementation of functions such as data crawling, storage filtering, data prediction, data visualization analysis, and system management.
