Model-driven Engineering

3 important questions on Model-driven Engineering

What is the MDE development life cycle?

PIM --> transformation --> PSM --> transformation --> Code

PIM: Platform independent model, which describes the system froma business perspective

PSM: platform specific model, specifies the system in terms of constructs available in a specific implementation technology

What is a transformation within the MDA framework?

A transformation is the automatic generation of a target model from a source model according to some transformation definition.

A transformation definition is a set of transformation rules

A transformation rule defines how one or more constructs in the source language can be transformed into one or more constructs in the target language.

What is the Low-code & No-code approach?

Is typically a one-shot modelling approach: straight from model/specs to code. No complex chains of refinement, no model-to-model transformations. Gaining a lot of traction

Advantages
- clearer message than model drive/based
- no complex chains of refinement or transformations
- more modelling expertise
- technology ismore mature
- benefits more clear

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
