In this short video we describe how you can register, enrich, discover, understand and consume big data in the Azure Data Lake Store by using the Azure Data Catalog. Using the Azure Data Catalog any analyst, data scientist or data developer in the enterprise can register their big data sources in their enterprise data catalog. The information in the data catalog can then be further enriched by others in the organization. This enables a variety of users to be able to search and discover these data assets and learn more about them. Once data is discovered, users can then leverage all the services in the Cortana Analytics Suite such as Azure Data Lake Analytics, Azure HDInsight and any other applications that are integrated with the Azure Data Lake Store.
