Models are never fully accurate representations of the systems they study because they simplify complex realities by focusing on specific variables while neglecting others. This abstraction is necessary to make the systems comprehensible and manageable, but it inherently introduces limitations and assumptions. Additionally, real-world systems often exhibit unpredictable behaviors and interactions that are difficult to capture in a model. As a result, models serve as useful tools for understanding and predicting trends, but they cannot perfectly replicate the intricacies of the actual systems.
The word you're looking for is "model." In various fields such as science, engineering, and education, models serve as simplified representations of complex objects or processes, enabling individuals to study and understand phenomena that are not directly observable. These can include physical models, mathematical models, or conceptual frameworks that illustrate relationships and dynamics within the system being studied.
Schematic system is a two dimensional chart depicting the elements and their linkages. eg Major elements of a personnel information system together with the materials and information flow. Static system model exhibit one pair of relationships such as cost quantity and activity time
Different kinds of models, such as physical models, mathematical models, or computer simulations, are used to represent the solar system because they help scientists and students to understand the complex interactions and dynamics within the system. Each type of model offers a unique perspective and level of detail, which can aid in studying different aspects of the solar system's components and their behavior. By using multiple types of models, scientists can gain a more comprehensive understanding of the solar system.

The DRF (Django REST framework) structure is based on the Model-View-Controller (MVC) architectural pattern. It follows the MVC pattern by separating different components of an application. Models define the data structure and relationships, views handle the logic for processing requests and generating responses, and controllers (also known as serializers in DRF) handle the conversion between models and JSON/XML representations.

Some limitations of models include simplifying real-world processes, overlooking complex interactions, and relying on assumptions that may not hold true in every situation. Additionally, models are only representations of reality and may not capture all variables or uncertainties present in the system being studied.
One statement that is not true about physical models is that they are always exact representations of the real-world system. Physical models are simplifications of real-world systems and may not capture every detail or aspect of the system. Additionally, physical models are subject to limitations in terms of accuracy and applicability.
Molecular models, like other types of models, are simplified representations used to better understand a complex system. They help visualize and explain the structure and properties of molecules. Like other models, they are based on certain assumptions and can vary in complexity depending on the level of detail needed.

They are both models, andthey both can be explained.
Models don't show all the important detail. For example, Models about the solar system don't sometimes show colour of the real shape of the planets (Earth is not exactly round) or the sometimes the real distance between planets.
Earth scientists often use models to represent complex objects or processes. Models can be physical, mathematical, or conceptual representations that help scientists better understand and study different aspects of the Earth system. By using models, scientists can simulate natural phenomena and make predictions about how the Earth works.
The data describing current conditions or characteristics might not be complete or accurate
Models are designed to serve particular purposes. In the case of astronomical models, they are designed to explain how things in the sky behave. For this purpose, heliocentric models are superior, because they are a closer description of what actually happens than geocentric models. They aren't ENTIRELY accurate, but close enough. However, if your purpose is to navigate on the surface of the Earth using a sextant, geocentric models are almost as accurate and make it a WHOLE lot easier to do the math. (I used to be an instructor in the US Air Force's celestial navigation school.)
