Quality evaluation method and system for multivariate heterogeneous data based on analytic hierarchy process

The invention relates to the technical field of enterprise data management, in particular to a multivariate heterogeneous data quality evaluation method and system based on an analytic hierarchy process. The evaluation system calls an enterprise business directory, and obtains a data set, a data module and assembly data; based on the data module, carrying out classification evaluation on the assembly data and designing a data quality index; establishing a data quality evaluation index system by using an analytic hierarchy process; determining a relative weight value of the data quality index based on the index system, and establishing a comprehensive evaluation function to obtain a quality comprehensive score corresponding to the data module; according to the equal weight mode of the data modules, data quality comprehensive score weighting is carried out on the corresponding data modules, a final data quality comprehensive evaluation score is obtained, and the method effectively evaluates the quality level of
