Logics in Models -> Model Driven Development

I am doing a project by having the logics in model instead of presenter/controller.

By keeping the business logic in model, We can able to abstract the logic such a way that it cannot be accessed outside and thereby causing bugs.

Also, The models are created by designing the class diagrams and sequence diagrams.

Looking for people to help me build that and provide feedback.

The project idea is same as IFTTT app.
