Abstract Software systems are subject to continuous changes to adapt to new and changing requirements. This phenomenon, known as software evolution, leads in the long term to software aging: The size and the complexity of systems increase, while their quality decreases. In this context, it is no wonder that software maintenance claims the most part of a software system's cost. In the last two decades, researchers have focused on mining and analyzing software repositories, to understand software evolution and support maintenance activities. In this presentation, we propose an *integrated* view of software evolution that combines different evolutionary aspects. Our hypothesis is that an integrated and flexible approach supports an *extensible* set of software maintenance activities. To this aim, we present a meta-model that integrates two aspects of software evolution: source code and software defects. We implemented our approach in a framework that, by retrieving information from source code and defect repositories, serves as a basis to create analysis techniques and tools. To validate our hypothesis, we devised and evaluated, on top of our approach, a number of analysis techniques that achieve two main goals: (1)Inferring the causes of problems, and (2) predicting the future of software systems.
