I. Introduction
Data analysis and mining are a very important part of the research of intelligent [1] information management system [2], which can make the precise control of information management system achieve faster implementation [3]. However, in the process of data analysis and mining [4], there is a problem of poor accuracy in the data analysis and mining scheme [5], which has a certain negative impact on the information management system [6]. Some scholars believe that the application of big data to the analysis [7] of information management system can effectively analyze [8] data analysis and mining schemes [9], and provide corresponding support for data analysis and mining [9]. On this basis, this paper proposes big data, optimizes the data analysis and mining scheme, and verifies the effectiveness of the model [11].
