Hi

I need to understand the 8 element below . I need to understand the pig picure big picure and how they are related to the process of reengineering. Please use simple English I need to understand:

The Source Code Reengineering Reference Model (SCORE/RM) is useful in understanding the process of reengineering of software. The model was proposed by Colbrook, Smythe, and Darlison [15]. The framework, depicted in Figure 4.6, consists of four kinds of elements: function, documentation, repository database, and metrication.

The function element is divided into eight layers: encapsulation, transformation, normalization, interpretation, abstraction, causation, regeneration,and certification.

Thank you
