Which model presumes systems are assembled from reusable components, scripts, or database routines ?
Show answer Hide answer
Answer: A. An application-composition model
Explanation
The application-composition model presumes systems are built from reusable components, scripts, and database routines. This model evaluates projects that assemble existing software modules rather than writing code from scratch. Application-composition techniques accelerate development by leveraging pre-existing software assets. COCOMO II includes multiple sub-models tailored to different software development phases and styles. Application composition relies on object management, rapid prototyping, and component reuse. Estimation in this model focuses on object points rather than traditional lines of code.
Developers use application-composition models when building software with visual programming tools. Enterprise systems integration projects often rely on assembling pre-built database routines and scripts. Component-based development significantly reduces time-to-market for modern software applications. Post-architecture models apply after detailed software designs and architectures have been established. Reuse models specifically calculate the effort saved by incorporating existing code modules. Early design models are used during architectural exploration before detailed component assembly.
