Study Notes
What is Software?
- Instructions (computer programs) executed for desired features and performance.
- Data structures used for efficient information manipulation.
- Documentation aids in understanding program operation and usage.
- Developed or engineered; not manufactured in a traditional sense.
- Does not "wear out" but can deteriorate over time.
- Primarily custom-built despite a shift towards component-based development.
Software Application Domains
- System Software: Operating systems and utilities managing hardware.
- Application Software: Programs for end-users, including word processors and spreadsheets.
- Engineering/Scientific Software: Tools for engineering calculations and simulations.
- Embedded Software: Software integrated into hardware devices.
- Product-line Software: Software for a specific set of products sharing common features.
- Web/Mobile Applications: Software designed for internet browsers and mobile devices.
- AI Software: Includes robotics, neural networks, and game-playing programs.
Legacy Software
- Software must adapt to new computing environments and technology.
- Required enhancements help implement new business requirements.
- Interoperability with modern systems or databases is crucial.
- Re-architecting is needed for viability in network environments.
Defining the Discipline
- IEEE defines Software Engineering as:
- Application of a systematic, disciplined approach to software development, operation, and maintenance.
- Study of methodologies and approaches in software development.
Software Engineering Layers
- Encompasses various layers essential for software development and management.
Process Framework Activities
- Communication: Engaging stakeholders and understanding requirements.
- Planning: Creating a roadmap for project execution.
- Modeling: Designing software architecture and components.
- Analysis of Requirements: Determining user needs and expectations.
- Design: Structuring the software solution based on requirements.
- Construction (Code Generation): Actual coding of the software.
- Testing: Verifying functionality and performance.
- Deployment: Releasing the software for user access.
