Master Data Management (MDM) is crucial for businesses to effectively leverage big data and analytics. The increasing volume of data generated daily, from various sources including mobile and cloud computing, AI, IoT and machine learning, presents opportunities for organizations to make insightful business decisions and gain a competitive advantage. However, the quality of data is critical for meaningful analysis. This is where MDM comes in, ensuring that data is clean, correct and relevant. MDM practices should be integrated into a company's data strategy to enable successful data analysis and drive business results.
