    Study Notes

    Object Oriented Software Engineering

    • Object-oriented software engineering is a software development approach that organizes software as a collection of discrete objects.
    • Objects encompass data structures and behavior.

    Nature of Software

    • Software is a product built and supported long-term by software professionals.
    • Software engineering includes a process, methods, and an array of tools for building high-quality computer software.
    • Software performs a dual role: as a product and as a vehicle for delivering a product.
    • As a product, software transforms, manages, and acquires information; it delivers computing potential of hardware and networks.
    • As a vehicle, it supports or directly provides system functionality, controls other programs, enables effective communication, and facilitates creation of other software.

    Software and Software Engineering...

    • The IEEE defines software as:
      • Instructions (computer programs) that, when executed, provide desired performance, features, and functions.
      • Data structures that help programs manage information adequately.
      • Documentation that describes program operation and use.
    • Software products can be developed for a particular customer or for a general market (e.g., generic vs. customized).

    Software Characteristics

    • Hardware:
      • Manufactured,
      • Wears out,
      • Built using components,
      • Relatively simple.
    • Software:
      • Developed/engineered,
      • Deteriorates,
      • Custom built,
      • Complex.

    Software Application Domains

    • There are various software application domains, including:
      • System software
      • Application software
      • Engineering/scientific software
      • Embedded software
      • Product line software
      • Web applications
      • Artificial intelligence software
    • New categories include open world computing, ubiquitous computing, netsourcing, open source, data mining, grid computing, cognitive machines, and software for nanotechnologies.

    Software Engineering

    • The IEEE defines software engineering as:
      • The application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software (i.e., the application of engineering to software).
      • The study of approaches, as described in (1).
    • Software engineering is a layered technology, including tools, methods, process, and quality focus.

    The Software Process

    • A software process (or simply process) is a collection of activities, actions, and tasks required to create a work product.
    • An activity is an attempt towards achieving a broad objective.
    • Actions are sets of tasks that result in a work product.
    • Tasks are designed to achieve specific, tangible objectives.
    • Example of a specific activity is communication with stakeholders to gather requirements from diverse, potentially non-technical users.

    The Generic Process Model

    • The generic process framework identifies a few activities applicable to all projects and a set of "umbrella activities" applicable across all processes.

    Framework Activities

    • Communication
    • Planning
    • Modeling (analyze requirements, design)
    • Construction (generate code, test)
    • Deployment

    Umbrella Activities

    • Software project tracking and control.
    • Risk management.
    • Software quality assurance.
    • Technical reviews.
    • Measurement.
    • Software configuration management.
    • Reusability management.
    • Work product preparation and production.

    The Process Flow

    Different process flows include:

    • Linear (activities performed in sequential order).
    • Iterative (activities repeated one or more times before proceeding).
    • Evolutionary (activities performed in circular manner, gradually improving the software).
    • Parallel (multiple activities performed simultaneously.)

    The Prescriptive Process Model

    • A prescriptive approach includes an orderly organization of framework activities.
    • Common prescriptive models include Waterfall, V-Model, Incremental Model, Prototyping, Spiral Model, and Unified Process Model.

    Waterfall Model

    • A classic life-cycle model with sequential phases.
    • Phases include communication, planning, modeling, construction, and deployment (followed by maintenance).

    Waterfall Model Design

    • Phases: communication (project initiation, requirements gathering), planning (estimating, scheduling, tracking), modeling (analysing requirements, design), construction(coding, testing), deployment(delivery, support, feedback).

    Waterfall Model Applications

    • Most suitable when requirements are defined, product definition is stable, technology understood, and resources are adequate for a short project.

    Waterfall Model Advantages

    • Simple and easy to use.
    • Easy to manage.
    • Good for smaller and well-understood projects.
    • Clearly defines stages and milestones.
    • Process and outcomes generally well-documented.

    Waterfall Model Disadvantages

    • No working software produced until late in the life cycle.
    • High risk and uncertainty.
    • Not suitable for complex systems with risk of changing requirements.
    • Difficult to measure progress during phases.
    • Scope adjustments are problematic and typically produce project delays.

    The V-Model

    • A variation on the Waterfall model, visualizing verification and validation activities. A crucial difference is testing begins early in the process and proceeds in reverse order of the design stages.

    The V-Model Applications

    • Well suited for systems that have strict requirements and well-defined methodologies (e.g., medical applications.).

    The V-Model Advantages

    • Highly disciplined, phases completed sequentially.
    • Good for smaller projects where requirements are well understood.
    • Simple and easy to understand and use.
    • Easy to manage due to rigidity of the model.

    V-Model Disadvantages

    • High risk and uncertainty.
    • Not a good model for complex systems or those with requirements at high risk of changing.
    • Difficult to measure progress during phases.

    Incremental Model

    • Delivers a series of releases (increments).
    • Development progresses through a series of iterations with each iteration producing a more complete version of the software .

    Incremental Model Advantages

    • Early implementation results.
    • Easier risk management.
    • Better ability to respond to changes.

    Incremental Model Disadvantages

    • Potential for substantial management resources necessary for coordinating work between increments.
    • May lead to confusion in overall project approach if not coordinated efficiently enough.

    Evolutionary Process Model (Prototyping Model)

    • Iterative; increasingly more complete versions of the software are produced in each iteration.
    • Prototyping is a crucial iterative activity of the process, providing customer feedback to refines requirements before implementation.

    Evolutionary Process Model (Spiral Model)

    • Iterative; increasingly more complete versions of the software are produced in each iteration.
    • Iterative development with emphasis on risk management and customer input.

    Advantages of the Spiral Model

    • Risk management
    • Flexibility in changing requirements
    • Higher customer satisfaction because early versions are delivered and problems fixed gradually.
    • Better management of complex applications.

    Disadvantages of the Spiral Model

    • Can be a costly model.
    • Time management is challenging as the number of stages is not always known upfront.

    Unified Process Model

    • A use-case-driven, architecture-centric, iterative, and incremental software development process closely connected with UML.
    • Encompasses five phases (Inception, Elaboration, Construction, Transition, Production).

    Agile and Process

    • Agile software development values customer satisfaction, early delivery, flexibility to respond to changes, and close collaboration between developers and customer users.
    • Process patterns in agile methodologies like Scrum, Extreme Programming (XP), Kanban emphasize project priorities, compartmentalized effort, and frequent customer feedback.

    Scrum - Agile Methodology

    • Employs iterative and incremental approach.
    • Key elements include: Product Backlog, Sprints, Daily Scrum.

    Extreme Programming (XP)

    • A widely used agile method.
    • Encompasses values, principles, and practices.

    Kanban

    • A lean methodology.
    • Emphasizes visualizing work, limiting work-in-progress, managing workflow, and prioritizing explicit policies.

    DevOps

    • A philosophy and set of practices that bridge development and operations teams.
    • Aims for continuous software delivery, automation, and continuous improvement.

    Review of Object Orientation

    • Object-oriented (OO) approach represents software as a collection of discrete objects combining data structure and behavior.
    • Aspects include:
      • Identity (discrete entities with inherent identity)
      • Classification (objects with similar structures and behaviors grouped into classes)
      • Inheritance (shared attributes and operations among classes)
      • Polymorphism (same operation may behave differently for different classes)
    • Core principles of Object Oriented Design Include: Abstraction, Encapsulation, Combining data and behaviour, and Sharing. The methodology has five key stages of implementation: System Conception, Analysis, System Design, Class Design and Implementation.
