Staying safe and sound thanks to MDSD (Dank MDSD gesund und vital bis ins hohe Alter)
Abstract
When is a software product be considered to be finished? In most cases, a product’s life ends with its discontinuation or replacement. Until this final state, nearly every software product undergoes an evolutionary lifetime. Large and long-lasting complex enterprise systems have a particular tendency to become unmaintainable and inflexible over time. This results in development pace stagnation and an increase in reaction time to customer demands.
This session will explain how common MDSD approaches could be leveraged to counteract these flaws. We will start with an introduction of our opponents like database migration and backwards compatibility and explain why they are not negligible. We will then elaborate on the non-functional aspects hidden in today's architectures. This presentation will illustrate how MDSD techniques help us to bring those underestimated lifecycle aspects under control without loosings flexibility. We will visualize proven patterns and best practises and explain how they could be incorporated into existing model-driven development processes independently. This irrevocably leads us towards the principles and benefits of anti-corruption layers. This pattern, coming from the domain-driven design camp and realized through model-to-model transformations, enables us to build robust and change-resistent solutions. To complement the theory we refer to a real world example throughout the whole session. This uses openArchitectureWare as the foundation on which to develop lifecycle-addressing solutions in the context of eHealth applications. We will illustrate where lifecycle problematics arise and how the presented solutions help in removing those obstacles in an agile environment. Finally, we will provide a short summary on the current movements and efforts in the field of lifecycle management and conclude with an outlook on future activities.
