description |
On the ground that design pattern is intricate by nature, its rationale traceability is prone
to be neglected leading to the misconception of the design rationale and forfeiture of its
main purpose. Design Rationale (DR) as the main subject of this research is considered
as the synthesis of the structure that is consistent with the model of an artifact, the
decisions, alternative approaches and the reasoning behind it. Hence, bypassing it will
result in poor quality systems engineering. Taking into consideration the facts that: (a)
design pattern is structured to offer a solution to a recurring problem; (b) its components,
design elements, methods along with other related elements are spread throughout the
pattern text; and (c) its rationale goals are ambiguously represented. Thus, the pattern
reader finds it problematic to capture the intricacy of its design. In order to decipher these
shortcomings, this research introduces an approach named Design Pattern Detection and
Design Rationale Decision Tree (DPD-DRDT) to support the structuring, evaluation, and
analysis of a design pattern employing a well-structured technique and methodology in
analyzing, validating and detecting design pattern existence in the source code. This study
proposes a method and implemented an associated tool which is designed to support two
of the major phases of the proposed approach, namely Phase 1 - Pattern Detection Process
(PDP), and Phase 2 - Tracing of Design Rationale (TDR). In Phase 1, PDP is supported
by the following processes: (1) defining the pattern structure; (2) uploading the target
program or source code; (3) extracting the basic elements which employs the aid of
NRefactory C# library in parsing the code and converting it to a text representation for
ease of reference and evaluation; (4) pattern detection process using the properties set in
(1) to validate against the data after the code has been parsed. In Phase 2, TDR needs two
inputs: (1) pattern detection result; (2) Design Rationale Decision Tree (DRDT) model of
the detected design pattern built via the implementation of the Rationale Traceability Framework (RTF). Each phase provides a mechanism that validates the class
relationships and properties comprehensively resulting to a reliable pattern detection
result. The rationale traceability framework has been implemented and represented in the
form of Design Rationale Decision Tree (DRDT), hence the open issues of design
rationale misconception and a chance to be neglected is resolved. Furthermore, a simple
and straightforward representation of the evaluation and decision result to determine
whether a design rationale goal is achieved or design pattern implementation needs to be
re-evaluated has been made available. The proposed approach is proved by the usefulness
of its output and a straightforward evaluation result resolves the intricacy of design
rationale traceability while achieving software quality is permissible.
