In the current business environment that is digitally integrated and globally dispersed, there are considerable governance challenges in maintaining uniform high quality product data across the various business enterprise resource planning (ERP) systems. Multi-ERP setups usually result in data silos, inconsistencies, redundancy, and compliance risks, which have a serious negative effect on the efficiency of operations and decision-making. The paper will address global data governance approaches to the sophisticated multi-ERP environments, with a closer look at the Oracle Product Data Hub (PDH), as a centralized master data management (MDM) platform. It talks about the governance problems of multi-ERP systems and explains how the Oracle PDH can overcome these problems using data consolidation, harmonization of workflow, workflow automation, and integrative capabilities. To outline the best practices and the future trends, the study relies on the industry-specific applications, strategic frameworks, and new technological trends such as cloud ERP, AI, and automation. Finally, the paper supports the importance of centralized governance structures facilitated by Oracle PDH in data quality, regulatory, and digital agility of the enterprise-wide.
