Diagrams

• Introduction of the big data platform is relatively easy since it is an extra layer added to the DWH functionality
• Relative easy big data patterns are available because the source is always the datawarehouse
• Introducing big data solutions for other functionalities than DHW is not possible.

• Easy (incremental) introduction of the Big Data functionality
• Integration of both functionalities requires attention for the introduction of the interconnect functionality because this can become a bottleneck in performance and configuration

• Appliance is developed, configured and often maintained by an external supplier
• It is introduced as a fully integrated solution therefore existing implementations of the DWH have to migrate to this solution
• Appliances are often introduced when a cloud solution is selected for the data platform

• Virtualisation layer encapsulate the internal confuguration of the two platforms
• The virtualisation layer requires a standardized data or objectmodel for the extraction by the consumers
• The virtualisation can become a bottleneck in a number of qualities like performance, integratability e.g.
