Abstract: A data analysis system is provided in the invention. The data analysis system includes a storage device, a field-data-description-file generating module, and a general data readiness analysis module. The storage device stores a plurality of raw data. The field-data-description-file generating module generates the field-data-description files corresponding to the raw data. The general data readiness analysis module obtains a score of the consistency indicator of the raw data according to the field-data-description files. The general data readiness analysis module obtains the data of the category which needs to be analyzed from the raw data according to the category of each field-data-description file. The general data analysis module obtains the score of the completeness indicator, the score of the accuracy indicator, the score of the validity indicator, and the score of the compaction indicator which all correspond to the data of the category which needs to be analyzed.

Abstract: A data analysis method includes steps of: obtaining at least one data table; wherein the data table includes a plurality of fields, and each of the fields stores field data; analyzing the field type according to the field data; determining a field category for each of the fields; calculating the similarity between the fields in different tables; determining the correlation between each of the fields according to the similarity; generating a field data description file according to the field type, the field categories and the correlations; and determining whether the field data description file is abnormal. A data analysis system is also disclosed.
