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.
