DQM stands for Data Quality Management. This refers to company-wide business processes that deal with the analysis and optimisation of data quality in a company. This way, the trust in the data is to be increased and forecasts and analyses become more accurate. Thus, data is increasingly viewed from an economic point of view and developed into a further “production factor” in a company. With the help of data quality management, companies want to constantly optimise the ever-increasing amount of data as well as the quality of the data.
