    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.
