Study Notes
Importance of Modeling
- A model simplifies reality and serves as a blueprint for systems.
- Different models can describe various aspects of a system, categorizing into structural (organization) and behavioral (dynamics) models.
- Achieves four key aims:
- Helps visualize a system's current or desired state.
- Allows specification of a system's structure or behavior.
- Provides a template for system construction.
- Documents decision-making throughout the modeling process.
Principle of Modeling
- Model selection significantly impacts problem-solving approaches and solution development.
- Models can be expressed at various levels of precision.
- Effective models represent realistic scenarios and are connected to real-world contexts.
- No single model suffices; complex systems benefit from multiple independent models offering diverse viewpoints.
Object Oriented Modeling
- In software development, two primary modeling perspectives exist:
- Algorithmic perspective focuses on procedures or functions as core components.
- Object-oriented perspective centers around objects and classes as fundamental building blocks.
- Definition of core concepts:
- An object is a specific entity from the problem/solution space.
- A class describes a group of similar objects.
Object Oriented Modeling Examples
- In a three-tier billing system architecture:
- User interface features objects like buttons, menus, and dialog boxes.
- Database includes tables representing domain entities such as customers, products, and orders.
- Middleware layer contains objects representing transactions, business rules, and higher-level entities.
Unified Modeling Language (UML)
- Designed to visualize, specify, construct, and document object-oriented systems.
