Software Development Life Cycle Sdlc Questions
There are several software reengineering techniques used in the Software Development Life Cycle (SDLC). Some of the commonly used techniques include:
1. Reverse Engineering: This technique involves analyzing and understanding the existing software system to extract its design and functionality. It helps in identifying the system's structure and behavior without any prior knowledge.
2. Restructuring: Restructuring involves modifying the existing software system's structure to improve its maintainability, performance, or other quality attributes. It may include activities like code refactoring, module reorganization, or database restructuring.
3. Forward Engineering: Forward engineering is the process of creating a new software system from scratch based on the requirements and design specifications. It involves activities like coding, testing, and deployment.
4. Program Transformation: Program transformation involves modifying the source code of the existing software system to enhance its functionality or improve its quality attributes. It may include activities like code optimization, code generation, or code migration.
5. Re-documentation: Re-documentation involves updating or creating new documentation for the existing software system. It helps in improving the understanding of the system's design, architecture, and functionality.
6. Reuse: Reuse involves utilizing existing software components or modules in the development of a new software system. It helps in reducing development time, effort, and cost.
7. Migration: Migration involves transferring the existing software system from one platform or technology to another. It may include activities like data migration, code migration, or platform migration.
These techniques are used in different stages of the SDLC to improve the quality, maintainability, and efficiency of the software system.
