The document discusses Oracle Enterprise Metadata Management (OEMM) which allows users to manage metadata, data lineage, and business glossaries. It harvests metadata from popular platforms including BI tools, ETL tools, databases, and big data tools. OEMM provides vertical lineage that shows traceability from business terms to IT artifacts, and horizontal lineage that traces columns and fields across multiple systems. It allows interactive exploration of metadata relationships through zooming and filtering capabilities.
