    Study Notes

    Introduction to Software Engineering

    • Software is a collection of instructions, data, or programs designed to operate a computer and execute tasks.
    • In simpler terms, software tells a computer how to function, encompassing applications, scripts, and programs running on devices like PCs, mobile phones, and tablets.
    • Without software, most computers are unusable. Web browsers are a type of software.

    What is Engineering?

    • Engineering focuses on creating products using scientific principles and methods.

    Software Engineering

    • Software engineering is a branch of engineering focusing on building software using scientific principles, methods, and procedures.
    • The end result of software engineering is creating reliable and efficient software products.

    What is Software?

    • Software includes computer programs and related documentation.
    • Software can be developed for a specific customer (bespoke) or the wider market (generic).
    • Generic software is designed to be available to many customers.
    • Bespoke software is tailor-made for a single customer.

    Programs vs. Software Products

    • Programs are typically small and used by the creator.
    • Software products are larger with many users and demand careful development, including a team of developers, well-designed interfaces, well-documented user manuals, and structured development processes.

    What is Software Engineering?

    • Software engineering involves the design, development, testing, and maintenance of software.
    • It uses systematic and disciplined approaches to develop high-quality, reliable, and maintainable software.
    • Software engineering involves modeling, problem-solving, and knowledge acquisition activities.

    Software Engineering Activities

    • Modeling: Software engineers create abstract models of systems to understand complex systems, focusing on relevant details.
    • Problem Solving: This includes steps like formulating the problem, analyzing it, designing, implementing a solution and deploying it.
    • Knowledge Acquisition: Software engineers collect, organize, and formalize data to develop system knowledge. Acquiring this knowledge is not always a linear process.
    • Rationale-driven: The development of effective systems involves understanding reasoning.

    Why Study Software Engineering?

    • Developing large-scale software programs
    • Solving complex programming problems
    • Become a better programmer
    • Develop quality software products

    Software Crisis

    • Software maintenance costs were comparable to development costs.
    • Projects often exceeded deadlines.
    • Software was typically inefficient and of low quality.
    • Software frequently did not meet user requirements.
    • Resources were not optimally utilized.
    • Debugging, maintaining and updating software presented challenges.

    Difference Between Computer Science and Software Engineering

    • Computer science focuses on the theoretical foundations of computing. This includes algorithms, data structures, complexity theory, and numerical methods.
    • Software engineering focuses on developing practical software, addressing practical problems in complex software products.

    The Software Engineering Body of Knowledge (SWEBOK)

    • The SWEBOK provides a structure for understanding and organizing software engineering knowledge.

    Software Processes

    • Software processes comprise a series of activities to develop or improve software.
    • Key activities include:
    • Specification: Defining what the system should do and its development constraints.
    • Development: Creating the software system.
    • Validation: Ensuring the software meets requirements.
    • Evolution: Modifying the software in response to changing needs.

    Attributes of Good Software

    • Maintainability: The ability to adapt to changes and meet new needs.
    • Dependability: Trustworthy and reliable performance.
    • Efficiency: Minimal resource use.
    • Usability: Ease of use for intended users.

    Challenges in Software Engineering

    • Legacy Systems: Maintaining and updating older software
    • Heterogeneity: Managing complex systems using numerous different hardware and software components.
    • Delivery: Meeting increasing demands for quicker software delivery.
