MDA/MDD: Model is not code!?
vhanniet - 2011/04/29Following my post on round-tripping, a discussion raised again on “what is model?” on Think in models. Here I try to focus on why “model is not code” in an MDA/MDD context. First of all, let’s define the investigation field: MDA/MDD: using models to generate (parts of) code with generators Model (in this context): a formal
MDA/MDD: don’t round-trip!
vhanniet - 2011/04/20In MDE life-cycle, round-trip engineering means ability to update a model based on source code reverse modeling. Funny practice: as the source code is issued from this model during the generation step, it’s a kind of “shoe is on the other foot”! More precisely, round-tripping is a way to work indifferently on model or source
ROI strategies for IS Modernization
vhanniet - 2011/04/08IS modernization projects have a difference with IS evolution projects: unlike a new application or an application which evolves on business demand, an application to be modernized does not bring any direct new business related functionality. So, at first glance, IS modernization projects are unlikely to be sold to CEOs, unless… To better focus on
Should MDA be the Holly Grail of Agile Manifesto?
vhanniet - 2011/03/23OK, I’m in a teasing mood… But let’s take the four Agile Manifesto values and have a look on MDA(*) through these values. Individuals and interactions over processes and tools The fact is that tools have a huge importance in MDA. Individuals, even interacting well, will not succeed if MDA tools don’t work (modeler and model-to-code
Path from ADM to MDA
vhanniet - 2011/03/11The Architecture Driven Modernization (ADM)(*) approach to migration projects follows a three steps workflow: Full source code reverse modeling, Model transformation from source architectural model to target architectural model, Target code generation combining target architectural model generation and algorithmic source code conversion to target programming language. The Model-Driven Architecture (MDA) approach to application development projects
IS modernization process vs target architecture
vhanniet - 2011/03/08Question is: in an ADM automated process, has the target architecture definition to be part of the process? Or has it to be (pre)defined regarding enterprise architectural IT plan? Answer is: both but enterprise business needs rank first. In an ADM process, a transformation path has to be found from the source code to the
IS modernization: kinds of move
vhanniet - 2011/02/28IS modernization means replacing IS components by other components which, while delivering the same functionalities to end users, bring business advantages or costs kills, or reduce business risks. IS evolution that brings new functionalities or an adaptation to an enterprise organisational move is not called IS modernization but… IS evolution! Business advantages: reducing time to
