    • Object-oriented design classes: Covers SOA and object-oriented design principles, serverless modeling, and business modeling (BPMN).
    • Domain specific languages (DSL): Highlights frameworks like Eclipse Modeling Framework (EMF) and Open Architecture Ware (OAW).

    Model Driven Development (MDD)

    • MDD: Software methodology focusing on creating models close to a specific field and less on informatics concepts.
    • MDA: The best-known MDD initiative, launched by the OMG (Object Management Group) in 2001.

    Agile Model Driven Development (AMDD)

    • AMDD: An agile version of MDD.
    • Key aspects include:
      • Identifying high-level scope
      • Identifying initial requirements stack
      • Identifying architectural vision
      • Iteration planning for modeling
      • Just-in-time (JIT) manner for stakeholder participation
      • Requirements evolve throughout the project
      • Develop working software via a test-first approach.
      • Executable specifications.

    Test-Driven Development (TDD)

    • TDD steps for developing software:
      • Add a test.
      • Execute tests; the new test will fail.
      • Add functional code to pass all the tests.
      • Run tests again.
        • If the tests fail, return to step 3.
        • If the tests pass successfully, continue with other functionality.
      • Refactor code for functional and testing purposes.

    Modeling Tools & Methodologies

    • IBM Rational Rose Modeler: Used for modeling.
    • BPMN: Business Process Modeling Notation - for creating graphical workflow representations of business processes.
    • Domain-Specific Languages (DSLs): Languages tailored to specific domains.
    • Working Frameworks: Eclipse Modeling Framework (EMF) and Open Architecture Ware (OAW).

    Aspect-Oriented Programming (AOP)

    • AOP: Isolates secondary or supporting functions from the primary program's business logic.
    • Advantages: Increases modularity by separating cross-cutting concerns, modularizes concerns at the source code level.
    • Basic Terminology:
      • Cross-cutting concerns: Aspects that impact other concerns.
      • Advice: Additional code.
      • Pointcut: Points at which the additional code (advice) is executed.
      • Aspect: Combination of pointcut and advice.
    • AOP Languages: Examples include AspectJ, Caesar, CLOS, Compose, JAsCo, and ObjectTeams.

    AOP - AspectJ - Example Applications

    • Specific examples of using AspectJ for various purposes, including Hello World and tracing student data changes or execution.

    SOA (Service-Oriented Architecture)

    • SOA approach involves dividing application functionality into smaller, independent units (services) that can be distributed over a network and combined to produce complex applications.
    • Services operate as independent functional units, addressing specific problems.
    • Reusability in various applications.

    Object-Oriented Design Principles

    • Architecture and dependencies: Discussion on degraded project scenarios
    • Design principles: Responsibility, dependencies, separation.
    • Architectural design principles: Reuse, versioning, closing, coupling, and dependencies.
    • Object-oriented design patterns: Abstract server, Adapter, Observer, Bridge, Abstract Factory.

    Architectural Degradation

    • Common types of architectural degradation: Rigid, fragile, immobilization, viscous, additional complexity, additional repetition, and opacity.

    Refactoring

    • Refactoring: Techniques and strategies for improving the internal structure of software without changing its observable behavior.
    • Signals that prompt refactoring: Duplicate code, long methods, large classes, long lists of parameters, instructions switching by type, polymorphism, speculative generality.
    • Outcomes: Reduced coupling and increased cohesion in code.

    GitHub and Other Collaboration Tools
