This research focuses on how to reengineer Cobol legacy systems
into object-oriented systems using Sward's Parameter Based Object
Identification (PBOI) methodology. The method is based on relating
categories of imperative subprograms to classes written in
object-oriented language based on how parameters are handled and
shared among them. The input language of PBOI is a canonical form
called the generic imperative model (GIM), which is an abstract
syntax tree (AST) representation of a simple imperative programming
language. The output is another AST, the generic object model
(GOM), a generic object oriented language. Conventional languages
must be translated into the GIM to use PBOI. The first step in this
research is to analyze and classify Cobol constructs. The second
step is to develop Refine programs to perform the translation of
Cobol programs into the GIM. The third step is to use the PBOI
prototype system to transform the imperative model in the GIM into
the GOM. The final step is to perform a validation of the objects
extracted, analyze the system functionally, and evaluate the PBOI
methodology in terms of the case study.
