Study Notes

Introduction to Software Engineering

  • Software engineering is concerned with theories, methods, and tools for professional software development.

Importance of Software Engineering

  • The economies of all developed nations are dependent on software.
  • More and more systems are software-controlled.
  • Expenditure on software represents a significant fraction of GNP in all developed countries.

Software Costs

  • Software costs often dominate computer system costs.
  • Software costs more to maintain than it does to develop.
  • For systems with a long life, maintenance costs may be several times development costs.

Types of Software Products

  • Generic products: Stand-alone systems marketed and sold to any customer (e.g., graphics programs, project management tools, CAD software).
  • Customized products: Software commissioned by a specific customer to meet their own needs.

Professional Responsibility

  • Engineers should not misrepresent their level of competence.
  • Engineers should be aware of local laws governing intellectual property (patents, copyright, etc.).
  • Software engineers should not use their technical skills to misuse other people’s computers.

ACM/IEEE Code of Ethics

  • The professional societies in the US have cooperated to produce a code of ethical practice.
  • Members sign up to the code of practice when they join.
  • The Code contains eight Principles related to the behavior and decisions made by professional software engineers.

Rationale for the Code of Ethics

  • Computers have a central and growing role in commerce, industry, government, medicine, education, entertainment, and society.
  • Security and trust are essential as software is intertwined with all aspects of our lives.

Software Engineering Diversity

  • There are many different types of software systems, and there is no universal set of software techniques applicable to all.
  • Software engineering methods and tools depend on the type of application, customer requirements, and development team background.

Application Types

  • Stand-alone applications: Run on a local computer, include all necessary functionality, and do not need to be connected to a network.
  • Interactive transaction-based applications: Execute on a remote computer, accessed by users from their own PCs or terminals (e.g., web applications).
  • Embedded control systems: Software control systems that control and manage hardware devices.
  • Batch processing systems: Designed to process data in large batches, process large numbers of individual inputs to create corresponding outputs.
  • Web services (Chapter 19): Allow application functionality to be accessed over the web.
  • Cloud computing: An approach to the provision of computer services where applications run remotely, and users pay according to use.

Web Software Engineering

  • Software reuse is the dominant approach for constructing web-based systems.
  • Systems should be developed and delivered incrementally.
  • User interfaces are constrained by web browser capabilities.

Case Study: Wilderness Weather Station

  • The government of a country with large areas of wilderness decides to deploy several hundred weather stations in remote areas.
  • Weather stations collect data from instruments that measure temperature, pressure, sunshine, rainfall, wind speed, and wind direction.
  • The system consists of a weather station system, a data management and archiving system, and a station maintenance system.
