Challenges with data quality testing and how to overcome them

One of the biggest challenges with data quality testing is the complexity of data infrastructure, which can make it difficult to identify and resolve data quality issues. To overcome this challenge, businesses should invest in data management tools and technologies that can automate data quality testing and monitoring - like dcupl. Additionally, businesses should develop data quality testing processes that include collaboration between IT and business units, ensuring that data quality issues are identified and resolved from multiple perspectives.

dcupl users monitor the data deliveries and thus ensure the data quality in the applications and therefore the full functionality and user experience.

  • For example, product data is monitored and checked with regard to quantity, missing prices, release characteristics for eCommerce, etc. - initially within the development and integration process and continuously according to definition in production.
  • Content blocks in your application are zip-code specific? Set up a data quality rule in dcupl and monitor the amount of filled zip-code properties in your data.
  • Is it business-critical if a technical value outside the permitted limit range is listed in the product catalog? Simply define the value range in the model and check it continuously with dcupl. This way nothing can go wrong!

By implementing a continuous data quality testing process, businesses can subsequently improve the quality of their digital services, whether it’s about the digitalization of inhouse business processes or digital transformation projects for end users.
