Chapter: Data Governance Quality And Controls
Master Data Management (MDM) is a strategic approach to managing and governing an organization's critical business data, ensuring that it remains consistent, accurate, and accessible across systems. MDM helps create a single, trusted source of key data (known as master data) used across various systems, departments, and business units. This centralization eliminates data silos, improves data quality, and enables better decision-making.
MDM includes processes for consolidating, standardizing, and governing data, and it plays a key role in ensuring data integrity and consistency. Important processes in MDM include the consolidation of multiple data fields, standardization of data field names, and the creation of a data dictionary.
1. Processes
1. Consolidation of Multiple Data Fields
Definition Consolidation of multiple data fields refers to the process of bringing together data from different systems into a single, unified version. This often occurs when data is spread across various systems, and different versions of the same entity (e.g., customer, product, supplier) are stored with slight differences. Consolidation helps to create a single, consistent view of master data, allowing the organization to reference and use the same data across all platforms.
