Extract

Extract functionality for receiving data from the source systems. This has a XML format and the source is either a webservice or a XML file. The data is extracted and prepared to be transformed

Logical modeling

The logfical or conceptual model is abstract in nature and is therefore independent from the implementation platform. In most cases this model must be readable for non IT stakeholderrs.

Transformation

Transformation function from the specific source data model to the standardized target data model. This can be a model or a protocol transformation. Often this transformation is divided in sub steps and these sub steps will be analyzed and modeled in the architecture of a specific data pipe implementation and components
