The article investigates the problem of unintentional data duplication, known in professional circles as duplicate records. Unlike managed duplication, which is used to ensure fault tolerance, duplicate records are a destructive artifact that arises during the stages of data collection, integration, and processing. The primary focus is on the consequences of duplication for information quality management in professional fields. Duplicate records can lead to decreased information quality, increased storage and processing costs, and errors in analytics and decision support. With the growing operational volume of data processing in complex systems, existing solutions fail to fully address the occurrence of such problems and have not offered a universal solution that would guaranteed eliminate this phenomenon or reduce the associated risks to a negligible level. Practical case studies demonstrate how this anomaly leads to significant operational costs, systemic errors in analytical processes, and the risk of incorrect management decisions. It is emphasized that existing approaches are reactive and do not ensure complete problem resolution. The necessity of developing proactive approaches to prevent this anomaly at the systemic level is substantiated.
Keywords:database, duplicate records, data duplication, information quality, information reliability, data quality
