What is the primary purpose of a Predictive model?

To create relationships in the data
To capture abstract syntax
To analyze the past for the future (correct)
To prescribe a decision based on all elements

What is the benefit of Model Driven Engineering when abstractions provided by implementation-level technologies are not satisfactory?

It reduces the need for boilerplate content (correct)
It eliminates the need for model transformations
It increases the complexity of the system
It only works with precise abstract syntax

What is the primary focus of a Descriptive model?

To prescribe a decision based on all elements
To capture abstract syntax
To analyze the past for the future
To create relationships in the data (correct)
