Below are the 10 main types of modeling

Physical models, mathematical models, and computer models are common types of scientific models.

Types of Models

• Physical models are smaller and simpler representations of the thing being studied.
• Conceptual models tie together many ideas to explain a phenomenon or event.
• Mathematical models are sets of equations that take into account many factors to represent a phenomenon.

• Fashion (Editorial) Model. These models are the faces you see in high fashion magazines such as Vogue and Elle.
• Runway Model.
• Swimsuit & Lingerie Model.
• Commercial Model.
• Fitness Model.
• Parts Model.
• Fit Model.
• Promotional Model.

Modeling helps to make learning concepts clearer. According to Barak Rosenshine, writer of Principles of Instruction: Research Based Strategies That All Teachers Should Know, students need cognitive support to help them learn to solve problems.

The main aim of conceptual model is to establish the entities, their attributes, and their relationships. Logical data model defines the structure of the data elements and set the relationships between them. A Physical Data Model describes the database specific implementation of the data model.

4 steps in designing a conceptual data model using the E-R diagram

1. Identify entity sets.
2. Define the value sets, attributes and primary key for each entity set.
3. Identify relationship sets and semantic information (cardinality, subtype/supertype) for each relationship set.

The main difference between Logical and Physical Data Model is that Logical data models help to define the data elements and their relationships, while the physical data models help to design the actual database based on the requirements gathered during the logical data modelling.

The logical design is more conceptual and abstract than the physical design. In the logical design, you look at the logical relationships among the objects. In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.

Logical data models are defined in terms of entities, attributes, and relationships. They reflect the business, its information and rules. A physical data model represents the computer database. Physical models look at data files and database design in terms of their implementation.
