Software Development Life Cycle Review

These flashcards cover key concepts, phases, and methodologies associated with the Software Development Life Cycle (SDLC), versioning, testing, documentation, and technology stacks.

What are the phases of the Software Development Life Cycle (SDLC)?

Phases include Planning, Design, Development, Testing, Deployment, and Maintenance.

What is the main focus of the Planning phase in SDLC?

Users of the solution, overall purpose, data inputs/outputs, legal compliance, risk identification, resource allocation, and project scheduling.

What is a Software Requirements Specification (SRS)?

A document that specifies the requirements gathered for the software project.

What is the main result of the Design phase?

Development of the software architecture and design document.

What activities happen during the Development phase?

Coding based on the design document, assigning coding tasks, and utilizing programming tools and languages.

What types of testing are conducted during the Testing phase?

Manual testing, automated testing, unit testing, integration testing, system testing, and acceptance testing.

What occurs during the Deployment phase of SDLC?

The application is released into the production environment and may go through user acceptance testing (UAT) before the final release.

What is the purpose of the Maintenance phase?

To identify and fix bugs, address user interface issues, and manage code enhancements.

What is the primary goal of functional testing?

To ensure the application is usable and accessible by testing its functionality.

What does non-functional testing verify?

Attributes like performance, security, scalability, and availability of the application.

What is regression testing?

Testing to ensure that recent changes do not adversely affect existing functionality.

What differentiates the Waterfall method in Software Development?

It's a sequential method where each phase must be completed before the next phase begins.

What is the significance of the V-shape model in software development?

Phases of verification correspond to validation phases, emphasizing testing at every stage.

How does Agile methodology differ from traditional methods?

It focuses on collaborative development through iterative cycles instead of a strict linear approach.

What is Semantic Versioning in software?

Versioning that indicates major changes (first number), minor changes (second number), patches/bug fixes (third number), and build number/date (fourth number).

What is the purpose of technical documentation?

To help developers understand code behavior and document engineers’ thoughts during implementation.

What is an IDE and its relevance in software development?

Integrated Development Environments help create and manage code, supporting multiple languages and integrating management tools.

What is the difference between front-end and back-end technologies?

Front-end is what users interact with (client-side), while back-end handles logic, functionality, and data security (server-side).

What is the purpose of version control systems?

To track changes made to source code by different developers and resolve conflicts.

What does CI/CD stand for in software deployment?

Continuous Integration and Continuous Delivery/Deployment.

What is a software stack?

A combination of technologies, including languages and frameworks used to create applications.

Give an example of a widely used software stack.

MEAN stack, which consists of MongoDB, Express.js, Angular, and Node.js.
