    Study Notes

    Object-Oriented Modeling Approach

    • One of the benefits of the object-oriented modeling approach is that it allows for a more detailed and nuanced understanding of the system being modeled.

    Object-Oriented System Development Life Cycle

    • The object-oriented system development life cycle progressively develops representations of the system during the analysis, design, and implementation phases.
    • During the analysis phase, the main purpose is to identify the problem domain and understand the requirements of the system.
    • The analysis model is refined and adapted to the environment in the design phase.

    Object-Oriented Modeling

    • As the model evolves during the object-oriented modeling approach, it becomes more detailed and refined.
    • In the early stages of the object-oriented modeling approach, the model is characterized by a lack of detail and a focus on overall system structure.
    • Encapsulation in object modeling refers to the practice of bundling data and methods that operate on that data within a single unit or object.

    Use-Case Modeling

    • A use case in the context of use-case modeling represents a complete sequence of related actions initiated by an actor.
    • The main goal of use-case modeling is to identify the functional requirements of the system.
    • An actor in use-case modeling plays a key role in initiating and interacting with the system.

    Object Modeling

    • An object in object modeling represents a real-world entity or concept.
    • A class diagram in object modeling represents a collection of objects that share common attributes and methods.
    • An object in object modeling is represented as a instance of a class.
    • An operation in object modeling represents an action that can be performed on or by an object.

    Unified Modeling Language (UML)

    • The Unified Modeling Language (UML) allows the modeler to specify, visualize, and construct artifacts.
    • The purpose of UML in the object-oriented systems development life cycle is to provide a standardized language for modeling and communicating system design.
    • UML is used to model and analyze the system during the analysis phase.
