Research On ERP System Data Quality Optimization Management From The Perspective Of Informationization

ERP system is based on data.The quality of these data directly affects the success or failure of ERP system implementation.Theoretical researchers and companies have begun to conduct theoretical and applied research on the quality of ERP data,but there are still many problems in the field of ERP data quality to be solved.This paper studies the data quality problems faced by ERP systems from the perspective of the overall system,establishes a methodological system for evaluating and improving ERP data quality,and can effectively detect and improve ERP data quality problems by measuring the quality of ERP data.Firstly,the theory of data quality was introduced,including the definition of data quality,evaluation methods,and the comparison of several typical data quality assessment methods.The comprehensive data quality management theory of MIT was introduced.Then introduced the data quality problem of ERP and its importance.On this basis,the ERP data quality is defined and analyzed,and the basic ERP data is classified according to its function.According to the characteristics of ERP implementation,ERP related data is divided into pre-operation data and system operation data.For the pre-operation data,starting from the source of the data collected by the function module,the mathematical modeling method was applied to establish a data quality assessment model that conforms to the characteristics of the ERP,providing the organization with the current status of the data quality level in order to improve it.For the data in operation,according to the characteristics of the modular structure of the ERP system,the fuzzy evaluation model based on the analytic hierarchy process(AHP)is used to analyze it,and the effects of uncertainties on the system are taken into consideration to provide reference for quality improvement.Based on the pre-operational data quality assessment model and results,a data quality improvement framework was proposed,and various quality elements such as data cleansing were used to improve.For the improvement of data quality in operation,IP-MAP method is used to analyze the data manufacturing process,find the reasons,and establish improvement programs to improve its data quality.Finally,this paper verifies the improved method of ERP data quality assessment through case studies.
