The Data Management Plane is a central architectural layer for managing, governing, and ensuring the quality of data across an organization. It integrates core services such as data governance, metadata management, Master Data Management (MDM), Reference Data Management (RDM), and ontology management to deliver consistent and compliant data frameworks. Supporting both real-time and batch ingestion, it enables seamless acquisition of data from diverse sources while embedding governance and metadata to ensure accessibility and trust. Through Data Repository Services, it offers scalable storage solutions—spanning Data Warehouses, Data Lakes, Lakehouses, and Marts—that unify structured, semi-structured, and unstructured data for analytical and operational needs. This plane supports modern data architectures like Data Mesh and Data Fabric, creating an interoperable environment for discovery, sharing, and analytics at scale.
