Understanding Software Concepts

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.
