The SAP Data Hub Integration Examples GitHub provides sample code for use cases in the SAP Data Hub. With these advantages, a data hub can act as a strong complement to data lakes and data virtualization by providing a governed, transactional data layer. For that reason, IT organizations have sought modern approaches to get the job done (at the urgent request of the business). Most data lakes are backed by HDFS and connect easily into the broader Hadoop ecosystem. And, while virtual databases can support transactions, the load is throttled by the performance of the underlying database systems, Build a data hub on top of a data lake, using MarkLogic Data Hub Service as the integration point for curating and governing data and the data lake for batch processing and data science, Consolidate as much data as possible via integration into one or more data hubs and expose that via data virtualization. For example, MarkLogic Data Hub can be used to integrate data from multiple sources and can be accessed as a federated data source using tools like Spark for training and scoring machine learning models. This is often called data federation (or virtual database), and the underlying databases are the federates. Examples of companies offering stand-alone data virtualization solutions are SAS, Tibco, Denodo, and Cambridge Semantics. Resume Tips for Data Entry.
