Modelo openEHR: avaliação da qualidade de projeto orientado a objeto

Abstract

Objective: To evaluate the quality of Object Oriented Design (OOD) of the openEHR Object Model, using Object Oriented (OO) metrics. Methods: An experimental study was designed and conducted using the openEHR Java reference implementation artifacts and with OO metrics of QMOOD quality model. Results: The results identified that the quality attributes of Reusability and Functionality satisfied the expectations of the quality model. The quality attributes of Flexibility and Extensibility proved unstable, while the quality attribute Understandability decreased. In addition, were identified six problems of OOD in detection strategies of problems of OOD. Conclusion: The openEHR Object Model gained new features and can reuse existing modules to solve a new problem. However, new requirements on existing resources can be difficult, as well as the adaptation of the project to new features. It also present difficulties to be learned and understood because of increase in the complexity.
