Accelerating Data Utility at Toyota: How vista Unifies Data Access and Governance via Data Mesh

Toyota Motor Corporation, with over 70,000 employees, initially centralized corporate, vehicle and customer data into a data library. This caused scalability issues due to a central team lacking domain knowledge, resulting in delays of several months. To solve this information disparity, Toyota created “vista,” a platform offering a company-wide data view.

Vista shifts from a centralized system to a decentralized data mesh, enabling domain experts to manage their own data. It uses a data fabric on Databricks Unity Catalog for centralized metadata governance and access control while keeping data physically owned by each domain. This zero-copy setup avoids duplication.Using the vista marketplace for search and Data Atelier for processing, Toyota adopted a self-service model that cut data wait times from months to weeks. This supports AI use cases like inspections via the AI Garage, preparing Toyota for future autonomous optimization.
