Design And Implementation Of User Portrait System Based On Bank Client Data Analysis

In recent years,with the rapid development of information technology in China,the application of big data is further extensive and in-depth.By 2019,the scale of Internet users in China has reached 850 million,and the scale effect of Internet users is conducive to the production of various applications of big data.The topic will focus on the related technology of big data,and take a local small and medium-sized bank in Sichuan Province as the research object to analyze the bank data and explore the business needs,so as to study the design and implementation of user portrait system Based on customer data.The bank is located in the remote and backward areas of Sichuan Province,facing the following problems : e-banking and Internet banking are in a new wave,how to adapt to the environment and the rapid development and wide application of various emerging technologies,and combine the bank's technology development strategy with new technologies such as big data.How to make use of the development mode of gradually changing from business-centered to customer-centered,actively understand customers,improve customer loyalty,and develop various products suitable for different groups of the market to provide secondary capacity for banks.Based on the above problems,this paper studies the design and implementation of user portrait system based on the bank data.The topic mainly draws lessons from the existing research results of user portrait theory,and combines with big-data-related technologies.The main research contents and objectives are as follows :First,after the study of the bank's comprehensive situation,analyze its existing business systems,analyze and sort out the existing data,and formulate the detailed requirements for integration and further mining,so as to provide the basis for the establishment of a set of big data system with clear analysis logic.Second,according to the business requirements,design and research user portrait system.By introducing related theories and methods,such as big data technology,data analysis technology,user label system and display system technology,the architecture design of big data and user portrait system is completed from bottom to top according to business requirements.Third,build,develop and implement user portrait system,study specific big data,data calculation,user tagging and system display.This paper focuses on the construction of big data architecture,data processing and analysis,the construction,application and classification of the label system.After the data collection,analysis and processing of the bank's core system,credit system and other major business systems,a complete set of user portrait system is finally achieved through the front-end data visualization system.The significance of this goal is to enable the system users of this bank to further analyze manually according to different categories of labels when using the system.Finally,in the fierce competition,products and services are used to retain old customers,compete for new customers and more market resources,and improve the core competitiveness,so as to improve the profitability.
