What is a model of a theory?
Model theory is a general theory of interpretations of axiomatic set theory . Mathematical structures obeying axioms in a system are called ” models ” of the system. The usual axioms of analysis are second order and are known to have the real numbers as their unique model .

What are the concepts of theory?
Theory explains how some aspect of human behavior or performance is organized. It thus enables us to make predictions about that behavior. The components of theory are concepts (ideally well defined) and principles. A concept is a symbolic representation of an actual thing – tree, chair, table , computer, distance, etc.

Theories are plausible explanatory propositions devised to link possible causes to their effects. Generally, models are schematic representations of reality or of one’s view of a possible world, constructed to improve one’s understanding about the world and/or to make predictions.
What is theory with example?

What is the difference between logical and physical models?
The logical model and the physical model are separate models . The logical model enables you to represent business information and define business rules. The physical model enables you to focus on the physical implementation of the model in a database.
What are the two types of theory?
There are countless theories but they can be clearly classified into two groups: Scientific Theories which are considered “true” or “facts” because they have been found experimentally to work and we know why they work, and Un-scientific Theories which have been found wanting when similarly experimentally tested.
