Paradigma orientado a aspectos, estudo de caso: sistema de auditoria para aplicações Java

Abstract

In software development, real world objects are represented through abstractions provided by programming paradigms. However, in some cases these abstractions are not sufficient to represent some kinds of characteristics present in software. Because of this, it was created Aspect Oriented Programming that provides a new abstraction level, called aspect; for the purpose of represent these characteristics in a clear and concise way. Aspect Orientation presents a solution for problems until then difficult to solve, as isolating concerns referring to application support activities. AOP reduces complexity and improves productivity in software development and maintenance. This work presents the Aspect Oriented Paradigm showing its advantages and efficiency through an audit trail system case study for Java applications. The system is implemented using object-oriented programming and aspectoriented programming, with the most common frameworks and tools.
