Study Notes

Software Engineering Basics

  • Good software must be understandable, usable, and compatible with other systems.
  • Essential attributes of good software are often referred to as "quality metrics" or "non-functional requirements".

Software Process Activities

  • Software specification: defining the software to be produced and its operational constraints.
  • Software development: designing and programming the software.
  • Software validation: checking the software to ensure it meets customer requirements.
  • Software evolution: modifying the software to reflect changing customer and market requirements.

Software Process Activities in Detail

  • Requirement Analysis: understanding stakeholder needs and documenting requirements in detail.
  • System Design: defining the system architecture, including high-level and detailed design.
  • Implementation (or Coding): writing code based on design documents.
  • Testing: verifying software functionality, including unit testing, integration testing, system testing, and acceptance testing.
  • Deployment: putting the software into production for user use.
  • Maintenance: keeping the system running smoothly, fixing issues, and making necessary changes or enhancements.

Software Engineering and the Web

  • The Web is a platform for running applications, and organizations are increasingly developing web-based systems.
  • Web services allow application functionality to be accessed globally.
  • Cloud computing is an approach to provision computer services, where applications run remotely on the cloud.
  • Users do not buy software but pay according to use.

Web Software Engineering

  • Software reuse is the dominant approach for constructing web-based systems.
  • Web-based systems should be developed and delivered iteratively and incrementally.
  • User interfaces are constrained by web browser capabilities, but technologies like AJAX allow rich interfaces to be created.

General Issues in Software Engineering

  • Heterogeneity: systems are required to operate as distributed systems across networks with different types of computers and mobile devices.
  • Business and social change: systems need to be able to change quickly to respond to emerging economies and new technologies.
  • Security and trust: software is essential in all aspects of life, and it is crucial to trust that software.
  • Scale: software development ranges from small embedded systems to Internet-scale, cloud-based systems serving a global community.

Application Types

  • Stand-alone applications: run on a local computer, including all necessary functionality and not requiring a network connection.
