Data quality


Data quality is the extent to which data sets meet the requirements and expectations in terms of accuracy, timeliness, relevance, completeness and consistency. High data quality is crucial for carrying out reliable analyses and making well-founded decisions.


The focus on data quality has increased as companies recognize that the quality of their data directly influences their business processes and analysis results. Poor data can lead to incorrect decisions, customer dissatisfaction, and financial losses. Data quality management has therefore become a central part of the corporate strategy.

Areas of application

Data quality is relevant across industries and plays a role in every area that makes data-driven decisions. This includes sectors such as finance, healthcare, retail, and industry. In industrial companies, data quality is particularly important for areas such as inventory management, production planning, customer service and compliance reporting.


High data quality leads to improved business decisions, increased efficiency and competitive advantages. It supports precise analyses, improves customer interactions and optimizes operational processes. Companies with high data quality can react more quickly to market changes and use their resources more effectively.

High-quality, up-to-date customer data enables accurate sales forecasts, effective marketing and improved customer service. Good data quality in a B2B retailer portal can mean that customer information is always up-to-date and complete, which increases customer satisfaction and loyalty.


Data quality is a critical aspect of data management that forms the basis for successful business decisions. Maintaining and monitoring data quality is therefore an essential task for every data-driven company.
