avoiding transformation technologies

Here I describe the emphasis on avoiding transformation technologies.

Why avoiding transformation technologies?

Non-standardized contracts result in the creation and implementation of different data models representing the same body of data. The differences are addressed by the use of a data transformation technology and mapping logic between one schema and another (e.g. XSLT style sheet).

Problems of data transformation:

  1. increased development effort through the definition of the mapping logic
  2. increased performance overhead through the mapping logic executed at runtime
  3. increased architectural complexity due to the transformation layers
  4. increased governance burden due to maintenance and evolution of the transformation layers

In order to support the goal of intrinsic interoperability, transformation technologies have to be avoided in a long-term. This goal is supported through contract standardization principle.
