Question

Model-­‐Driven Architecture (MDA) assumes that it is possible to translate a model of a system into executable code.

• Do you think this is feasible today?
• If it is not feasible today, why not?

Answer 1

Model Driven Architecture is a software development approach which makes s use of system model to executable codes in software development.

MDA is feasible or not can be examined by seeing its pros and cons first:

Pros:

• It is faster and cost effective method because of reusability.
• Main importance is given on developing model before any coding starts. Thus helps saving code time and make the code less error prone and have better quality.
• Any change first can be done and seen in models before doing in actual coding
• Better team coordination and working knowledge.

Cons

• Code needs to be regenerated for minor changes.
• Any additional requirements may turn model obsolete.
• It may be hard to change and regenerate code.
• Modeling environment may not be compatible with software technology
• Team needs to understand lot of other things than actual coding.
• New models are difficult to create and though of

Model Driven Architecture is a complicated approach which needs to change according to changing world in order to serve complicated software development of the market.

Model driven architecture is less feasible as abstraction level is very low and complex. Flowchart one of the model driven architecture tools can be as complex as the code itself. Thus any change needs to be done in complex flowchart and code as well.

Now models have object-oriented looks which itself makes use of object modeling which helps in making MDA feasible in software making approach.

Feasible or not feasible depends on type of software product needs to be developed. MDA allows faster builds, rebuilding, tested environment which is feasible for projects which are of complex nature and not feasible for simple software requirements.
