    Study Notes

    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.
