    Study Notes

    Introduction to Object-Oriented System Development

    • Object orientation is a programming paradigm that focuses on the concept of objects as the building blocks of software systems.
    • An object is a distinct entity within a software system, representing something in the real world.
    • Objects have attributes that store information (data) and methods that define their behavior and actions.
    • The concept of data encapsulation is integral to object orientation, where an object's internal attributes are hidden from external access.
    • Methods enable objects to interact with each other by accessing or modifying each other's attributes.
    • Object orientation offers benefits for software complexity management, such as simpler extensibility, better testability, and improved maintainability.

    Case Study: An Online Shop for Media

    • For an online shop selling media (books, music, etc.), a "Customer" class is a good example of object-oriented modeling.
    • Each "Customer" object has attributes such as last name, first name, birthdate, and sex.
    • These attributes are defined within the "Customer" class, encapsulating the data associated with each individual customer.

    Properties of Attributes in Object-Oriented Modeling

    • Each attribute within a class has specific properties that define its characteristics and behavior.
    • Essential properties include a name for the attribute (e.g., "firstname"), a data type (e.g., "Date", "String", "Integer"), and a default value (e.g., "2020-01-01").
    • Other optional properties include constants (indicating whether the attribute can be changed) and source (the origin of the value).

    Example Scenario: A Coffee Machine

    • Object orientation can be used to model real-world scenarios.
    • A simple coffee machine can be decomposed into cooperating objects like a water tank, water pipe, filter, heating element, hot plate, and coffee pot.
    • Each object has specific attributes and methods representing its functionality.
    • The interaction between these objects defines the overall behavior of the coffee machine.

    Interaction and Cooperation Between Objects

    • Object-oriented systems rely on interaction and cooperation between objects.
    • Objects communicate with each other by invoking methods on each other.
    • The state of an object is defined by the values of its attributes.
    • Objects created from the same class with identical attribute values are considered identical.

    The Software Development Process

    • The software development process involves various distinct phases.
    • Object-oriented software development follows a systematic approach, typically including phases such as analysis, design, implementation, testing, and deployment.
    • These phases can be executed iteratively and incrementally for better adaptability and flexibility.
