SDLC
What does SDLC stand for?
Software Development Life Cycle.
What is software engineering?
It is the systematic application of engineering principles to design, develop, test, and maintain software that meets user needs.
What is the main focus of the Reuse-Oriented Model?
Building new software by integrating existing, pre-built components.
Name one advantage of the reuse-oriented model.
It provides fast, cheap solutions using existing products.
Name one type of project that uses the reuse-oriented model.
E-commerce platforms.
What happens during the Planning phase?
Requirements are gathered, costs estimated, schedules made, and objectives defined.
How does software engineering differ from simple programming?
It focuses on maintainability, planning, design, and testing — not just writing code.
Why was the reuse-oriented approach develope
To save time, reduce costs, and increase reliability by reusing proven parts.
How does this model encourage partnerships?
It builds strategic supplier relationships for reusable components.
How do e-commerce sites reuse components?
They integrate modules like user login, payment, and catalog systems.
During which phase is the system coded?
Implementation phase.
Give one real-world example of software engineering.
Developing a hospital patient portal that requires design, coding, testing, and maintenance.
What is the key difference between traditional models and the reuse-oriented model?
Traditional models build software from scratch; the reuse-oriented model assembles software using existing components.
Name one disadvantage of the reuse-oriented model.
Limited functionality or compatibility issues.
What is a reusable component for payment systems?
A secure payment processing module like PayPal or Stripe integration.
Why is testing important in the SDLC?
It identifies bugs and ensures the software meets client requirements.
Name two key attributes of well-designed software.
Examples: Functionality, Portability, Maintainability, Security, Usability, Reliability.
Give an analogy used to describe the reuse-oriented model.
It’s like assembling Lego pieces instead of building from raw materials.
What is a licensing issue that can arise with reused components?
Restrictions or costs from freeware, shareware, or maintenance fees.
What is one benefit of reusing product catalog components?
They ensure consistent product data across multiple platforms.
What is done during the Maintenance phase?
Fixing bugs, managing updates, and improving performance after deployment.
Why is security a key attribute of software engineering?
Because it ensures business continuity, customer trust, and protection of sensitive data from cyber threats.
What is one example of software reuse in a school management app?
Using Google Sign-In for login or a pre-made attendance module.
What does “customer lock-in” mean in this context?
Dependence on a specific vendor for upgrades or licensing.
List one fundamental step in creating a reuse-oriented project.
