What is the Difference Between Static and Dynamic Modelling?

🆚 Go to Comparative Table 🆚

The main difference between static and dynamic modeling lies in the representation of a system's behavior over time. Static models represent the system at a specific point in time, while dynamic models represent the system as it changes over time.

Static Models:

  • More structural than behavioral.
  • Represent the system at a specific point in time.
  • Use class diagrams and object diagrams to depict static relationships between system components.
  • More rigid, as they are time-independent views of a system.

Dynamic Models:

  • Focus on the behavior of the system's components.
  • Represent the system as it changes over time.
  • Use sequence diagrams, state transition diagrams, and interaction diagrams to show the sequence of operations, state changes, activities, interactions, and memory utilization.
  • Flexible, as they can change with time and show what an object does with many other objects.

In summary, static models provide a snapshot of a system at a specific moment, while dynamic models show how the system evolves and changes over time. Static models are more structural and rigid, whereas dynamic models are more behavioral and flexible.

    Here is a table comparing the differences between static and dynamic modeling:

    Feature Static Modeling Dynamic Modeling
    Definition A static model is a representation of a system that does not change with time. It is more structural than behavioral and is usually depicted using class diagrams and object diagrams. A dynamic model is a representation of a system that changes with time. It focuses on the behavior of the system and its components, including sequence of operations, state changes, activities, interactions, and memory.
    Time Dependence Static models are time-independent, meaning that providing the same set of input values will always result in the same set of output values. Dynamic models change with time, and the output values at any instant in time are dependent on not only the input values at that time, but may also be dependent on all of the input values presented to the model at previous times.
    Differential Equations Static models do not use differential equations. Dynamic models often use differential equations to represent the system's behavior as it changes over time.
    Flexibility Static models are more rigid, as they cannot be changed in real time. Dynamic models are more flexible, as they can change with time.
    Memory Static models do not have internal memory. Dynamic models have internal memory, provided by state variables.
