Study Notes
Software Engineering Overview
- Software engineering combines science and art to construct significant software systems effectively and reliably.
- Primary goals include delivering software on time, within budget, with satisfactory performance, and ensuring correct operation.
- Economies of developed nations heavily rely on software; most systems are software-controlled.
Software Costs
- Software expenses often exceed hardware costs in computer systems.
- Maintenance costs for software typically surpass initial development expenses; can be several times higher for long-lived systems.
- Cost-effective software development practices are essential to managing these financial aspects.
Software Product Types
- Generic Products: Stand-alone systems sold to any interested customer (e.g., PC software for graphics or project management).
- Customized Products: Tailored software designed to meet specific client needs (e.g., embedded systems, air traffic control software).
- Ownership of specifications differs; developers control generic product specs while customers define requirements for customized products.
Importance of Software Engineering
- Increasing reliance on advanced software systems necessitates the production of reliable, economically viable solutions.
- Implementing software engineering methodologies is generally more cost-effective in the long term compared to ad-hoc programming.
Software Process Activities
- Key software processes include specification, development, validation, and evolution.
- Specification involves defining software requirements and operational constraints with customer input.
General Issues in Software Engineering
- Heterogeneity: Need for systems to integrate across various devices and networks.
- Business and Social Change: Rapid developments require adaptable and quickly deployable software.
- Security and Trust: Software design must ensure user trust and secure operations.
Software Engineering Diversity
- A variety of software systems exist, necessitating different engineering techniques tailored to application type and project requirements.
Application Types
- Stand-alone Applications: Local applications functioning independently without network reliance.
- Interactive Transaction-based Applications: Web-based apps requiring remote access (e.g., e-commerce).
- Embedded Control Systems: Used to manage hardware devices, often outnumbering other types of software.
- Batch Processing Systems: Designed for large-scale data processing.
- Entertainment Systems: Software aimed at user engagement and entertainment.
- Modeling and Simulation Systems: Created by scientists for analyzing complex processes and interactions.
- Data Collection Systems: Utilize sensors to gather and relay environmental data.
- Systems of Systems: Comprises multiple interconnected software systems.
Software Engineering Fundamentals
- Important to adopt a structured software development process.
- Prioritize dependability and performance across all systems.
- Understanding requirements and specifications is crucial for successful implementation.
- Reuse existing software when feasible to minimize costs and time.
Software Engineering and the Web
- Web applications are increasingly favored over traditional local systems; organizations utilize the web extensively for application deployment.
- Cloud computing allows remote application access, offering usage-based payment models.
Web Software Engineering
- Emphasizes software reuse; systems often built from pre-existing components.
- Development of web-based systems is typically incremental, accommodating evolving requirements.
- User interfaces in web applications often constrained by browser capabilities, necessitating compromises for usability.
Software Engineering Ethics
- Ethical conduct transcends technical skills; engineers are expected to uphold honesty and professional integrity.
- Issues include confidentiality, dilemmas in adhering to management policies, and ethical concerns regarding product development.
Ethical Dilemmas
- Instances include conflict with upper management policies and risks involved in releasing inadequate safety-critical software.
Case Studies
- Insulin Pump: Critical system for diabetic patients that delivers insulin based on blood sugar data.
- Mental Health System: Maintains patient management records for mental health care.
- Weather Station: Collects and relays meteorological data from remote locations.
Essential Requirements for Insulin Pump
- Must ensure timely delivery of insulin as needed.
- Reliability in performance, maintaining accurate dosage based on real-time blood sugar analysis.
- Design must guarantee adherence to these critical requirements.
