Serial integration is implemented by introducing a big data platform for the transformation and extraction of unstructured and semi structured data as source for the EDWH functionality.

Characteristics
- 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.

In the appliance integration of a big data platform with DWH functionality the appliance acts like a black box in which all functionality is integrated in a (proprietary) solution. This solution is configured for optimal performance of transformation and analysis.

Characteristics
- 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

The parallel integration is an extension of the DWH functiionality with the Big Data Platform. This extension makes it possible to use both functionalities side by side.

Characteristics
- 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
-

This integration pattern has a close relation with the parallel integration, however there is an extra layer introduced for the virtualisation and standardisation of data extraction to consumers of the data.

Characteristics
- 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.
-
