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.
