摘要:Design pattern is a set of solutions that is used to solve software development common problems. The purpose of design pattern utilization is to improve software quality. Various design patterns have been proposed. One of them is Patterns of Enterprise Application Architecture (PoEAA) which are specified for enterprise application. However, there are lacks of literature that discuss these patterns. This research conducts a quantitative study to assess the impact of design pattern on software maintainability. We use Academic Information System of Institut Teknologi Sepuluh Nopember as a case study. It is an enterprise software which has Anemic Domain Model. We perform refactoring into the existing systems using suitable PoEAA. We measure its maintainability using C&K and three additional metrics, prior and after the refactoring process. The measurement results are then evaluated to obtain the impact. Based on the experiments, we clearly observe that PoEAA utilization could significantly restructure the anemic domain model of AIS. The maintainability is increased especially in presentation layer. PoEAA also eliminates duplicated methods in service and repository layer of the existing version of AIS. However, there are several drawbacks of the improvements.
