branch of both compsci and engineering focused on designing, developing, testing, and maintaining software apps.

Attribute - easy to update and adapt to changing user's needs

Attribute - Reliable, safe

Attribute - uses system resources optimally

Attribute - easy to use and fits well with users' other tools

programs designed to help users perform specific tasks on device

Soft App - Run locally on a single computer without requiring a network (Microsoft Word)

Soft App - Run on a remote server, accessed through a browser, respond to user input (Amazon)

Soft App - Built into hardware to control or manage devices (Car engine control software)

Soft App - Process large amounts of data in batches for business operations (Payroll processing system)

Soft App - Designed for personal use to entertain the user (Netflix)

Soft App - Collect data and send it for processing (online survey tool)

Soft App - Composed of multiple software systems working together (Air traffic control system)

Pre-built systems that are marketed and sold to any customer who wishes to buy them

specification - software developer

Software developed specifically for one client, designed to meet their exact specifications and processes

specification - customer

Fundamental - Defining what the system should do

Fundamental - software is designed and programmed

Fundamental - software is checked to ensure that it is what the customer requires

Fundamental - changing the system in response to changing customer needs

SLDC - 1. Gathers info about requirements

SLDC - 2. Plan architecture, technologies, and components

SLDC - 3. Write code based on design specifications

SLDC - 4. Ensure software works as intended

SLDC - 5. Release product into a live environment

SLDC - 6. Fix bugs, update features, and improve performance

Linear and sequential, each phase must be completed before the next, easy to manage but not flexible for changes

Projects with well-defined requirements

Simple version then improve through iterations, requires careful planning to make sure increments are meaningful

Projects with evolving requirements

Iterative and Collaborative, breaks development into cycles (sprints), really flexible

Dynamic projects with frequent changes

Cultural and technical approach that integrates development and operations to enable CI/CD and collaboration (Github Actions)

Automating and improving the delivery of software

Continuous Integration/Continuous Delivery/Deployment

Soft Env - Used by developers, no client data

Soft Env - Used by QA engineers, no client data

Soft Env - Used by QA engineers & clients for UAT, limited production data

Soft Env - Used by clients, full production data

Developers frequently merge their code into a shared repo

Relies on a deployment pipeline visibility, feedback, continuous deployment
