Data Mesh is a decentralized approach to data management that treats data as a product and assigns ownership to domain-specific teams. By breaking away from centralized architectures like data warehouses and lakes, it ensures scalability, agility, and improved data quality. Emphasizing principles like domain-oriented ownership, self-serve infrastructure, and federated governance, Data Mesh enables faster insights, fosters collaboration, and breaks down silos. With applications across industries like e-commerce, healthcare, and finance, it transforms how organizations leverage data while addressing challenges like governance complexity and cultural shifts.
