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.

Overview of the transformation from file based data to a data target
Overview of the transformation from a relational database to a data target
In this diagram a description of the datapipe from an (webservice) or XML file source to the target datamodel is described. This is based on the transformation of a XML model to an intermediate tabular or relational model and this is then processed in an ETL process to transform the source data model in a number of steps to the required target model.
