Software Re-engineering Concepts Quiz

SCORE/RM Model Components

• The four kinds of elements in the SCORE/RM model are: Source Code, Function, Repository Database, and Reengineering.
• The function element consists of eight layers.

Function Element Layers

• The first six layers of the function element focus on representing the software's functionality.
• The final three layers of the function element aim to analyze and quantify the potential benefits of applying reengineering techniques.

Reengineering Element

• The Reengineering element quantifies improvements in software as a result of reengineering.

Repository Database

• The repository database element acts as a centralized storage for all information gathered during the reengineering process.

Reengineering Process Phases

• The analysis and planning phase represents understanding the existing system and deciding on the reengineering goals and strategies.

SCORE/RM Model Arcs

• In the SCORE/RM model, the labels on the arcs denote the types of transformations that can be applied to the elements.

Analysis Phase

• The primary technical issue addressed during analysis in the context of the software reengineering process is understanding the existing system's structure, functionality, and behavior.

Software Reengineering Phases

• The phase model of software reengineering consists of five distinct phases: Analysis and Planning, Reverse Engineering, Restructuring, Forward engineering, and Redesign.

Planning Phase

• The planning phase of the phase reengineering model includes defining project scope, setting objectives, and developing a detailed plan for the reengineering project.

Function/Function Interface

• In the SCORE/RM model, the Function/Function interface (N)-FF represents interactions between different functions within the software system.

Interface Types

• The three types of interfaces explained in the SCORE/RM model are:
  • Function/Function interface (N)-FF: Represents interactions between functions.
  • Data/Function interface (N)-DF: Reflects the data used by different functions.
  • Function/Data interface (N)-FD: Shows how functions manipulate data.

Repository Database Storage

• The SCORE/RM model's repository database stores all information obtained during the reengineering process, including source code, function details, and data about potential improvements.

System Renovation Alternatives

• Table 4.1 suggests several alternatives to renovate a system, including:
• Encapsulation: To improve maintainability and reusability.
• Data Abstraction: To simplify data access and increase flexibility.
• Modularization: To break down complex systems into smaller, manageable units.
• Data Normalization: To improve data consistency and reduce redundancy.
