Study Notes
Nature of Software
- Software consists of instructions (computer programs) that provide desired functionality and performance.
- Data structures in software enable effective information manipulation.
- Documentation is essential, detailing the operation and proper use of software programs.
Characteristics of Software
- Software is engineered rather than manufactured.
- Unlike hardware, software does not "wear out" but can deteriorate over time.
- Although there is a trend towards component-based development, most software remains custom-built.
Software Application Domains
- Various domains include:
- System software
- Application software
- Engineering and scientific software
- Embedded software
- Product-line software
- Web and mobile applications
- AI software (e.g., robotics, neural networks, game playing)
Legacy Software and Reasons for Change
- Software must adapt to new computing environments and technologies.
- Enhancements are needed to address new business requirements.
- Interoperability with modern systems or databases necessitates software extensions.
- Re-architecting is often required for network viability.
Defining Software Engineering
- Defined by IEEE:
- A systematic, disciplined, quantifiable approach to software development, operation, and maintenance.
- The study and application of engineering principles to software.
Software Engineering Layers
- Includes several layers essential for software development and management (details not provided).
Process Framework Activities
- Key activities in software development involve:
- Communication
- Planning
- Modeling
- Requirements analysis
- Design
- Construction (code generation)
- Testing
- Deployment
Umbrella Activities in Software Engineering
- Include tracking and control, risk management, quality assurance, technical reviews, measurement, configuration management, and work product preparation.
Process Adaptation Requirements
- Variation in activity flow, task definition, and interdependencies among tasks impacts process adaptation.
- Differences in quality assurance application methods and project tracking can influence project outcomes.
- Customer involvement and team autonomy levels vary across projects.
Essence of Software Engineering Practice
- Four essential steps suggested by Polya:
- Understand the problem through communication and analysis.
- Plan a solution by modeling and designing software.
- Implement the plan through code generation.
- Assess results for accuracy via testing and quality assurance.
Understanding the Problem
- Identify stakeholders and their stakes in the solution.
- Determine unknowns and necessary data, functions, and features.
- Evaluate if the problem can be compartmentalized into smaller, manageable parts.
- Explore graphical representations or create analysis models for better understanding.
