Design Pattern Evaluation on A RESTful API Wrapper: A Case Study of Software Integration with An Internet Payment Gateway using Model-Driven Architecture

A proper use of design patterns has proven to be very useful in the

development of robust applications over time. In this paper, the design patterns

are introduced in the early stage of the software development where model-driven

architecture is used as the engineering approach. A RESTful internet payment

gateway API (Application Programming Interface) wrapper is selected as the

case study. At the beginning, Platform Independent Model (PIM) is created as

the domain model. After that, the PIM is transformed into the Platform Specific

Model (PSM). Before converting the PSM into the source code, three design

patterns such as builder, observer, and factory pattern are added into the model.

To evaluate the impacts of implementation, static analysis is used to examine the

generated code before and after adding the design patterns. The result shows that

the design decision increases cohesion, complexity, coupling, inheritance, and

size metrics of the source codes.
