Big data really is a big deal The opportunities of insight, innovation, and impact are virtually unlimited. Realizing the opportunities, however, depends largely on managing the data well through the entire lifecycle from ingestion to application. That’s a tall order with many moving parts-data, metadata, storage, processing, quality, security, search, preparation, analysis, and more. Big data management involves both management practices for big data and big processes for data management. Big data is more than just NoSQL and unstructured data. It encompasses the entire data hub-data lake, data warehouse, data marts, master data, and ODS-as well as distribution of that dat to sandboxes and local data extracts. All data of enterprise interest, internal or external, that needs to be shared is big data. And big data must be managed.
