Hybrid data estates create silos, duplicate datasets, and “unknown” data flows. Teams lose time finding the right data, can’t trace lineage for audits, and take on risk when changes break downstream reports and apps. Rocket® DataEdge™ is a metadata-driven data intelligence, integration, and virtualization platform. It connects and delivers data across heterogeneous systems while adding business and technical context, lineage, and end-to-end visibility so teams can understand what data exists, where it’s used, and how it moves. Key capabilities: • Metadata capture and cataloging with glossary/tags/ownership • Lineage and impact visibility to troubleshoot and govern change • Seamless hybrid data integration plus virtual/federated access • Connectors/APIs for mainframe, distributed, and cloud sources/targets • Policy-driven security/governance controls across environments Outcome: faster time-to-data with fewer brittle pipelines, audit-ready visibility, and more trusted analytics/AI inputs.
