Biography Jean-Luc Hainaut

Dr. Hainaut is recognized for his fundamental contributions to both principles and practice in data modeling, database design, data reverse engineering, and data-focused systems evolution. Since the 1970s, Jean-Luc Hainaut's work at the Université Notre Dame de la Paix in Namur, Belgium, on the advancement and promotion of data technologies has been exceptional. The early introduction of binary semantic modeling and entity-relationship concepts, as well as multi-level model-driven database design methods, paved the way for many advances in systems development methods and tools. His application of transformation techniques in data-modeling and database reverse engineering approaches have enabled greater understanding of database structure and utilization in both scientific and business applications. Prof. Hainaut and his colleagues at Institut d'Informatique built, fostered, and nurtured a research environment at Namur that has a long and continuing reputation for deep contributions to theory, research, practice, and technical outreach in software and data engineering. This exemplifies the kind of quality achievement in advancing and applying software methods research that Wayne Stevens sought for the software industry. 


Using biology and ecology as inspiration for software maintenance?

The presentation can be download here.

As a bioengineer and marine ecologist, I probably have a different view on software complexity and evolution than specialists in this field. The literature as well as discussion with colleagues suggests that there may well be 'hidden gems' in traditional ecology for software engineers. In this presentation, I will compare a couple of biological and software (mostly Open Source) ecosystems and suggest a few ideas that may be useful for software maintenance research.

Two key aspects appeared to me when I started to work on Open Source software ecosystems: (1) the difference in terminology in biology and software engineering, and (2) the much more collaborative trends in software ecosystems, compared to biological ecosystems.

The first aspect is mostly a technical issue that unfortunately creates a strong barrier between software engineers and biologists. So, it should be worth considering using the same or similar meaning for the same terms, like ecosystem, resource, consumer,... in both disciplines.

The second aspect is much more interesting. So, software ecosystems exhibit much more collaboration and much less competition than biological ecosystems? Since biologists consider competition as one of the major driving forces for biological evolution (recall Darwin and his natural selection mechanism through struggle for existence), it is very clear that the fundamental rules that drive both biological and software ecosystems are completely different.

So what? Is there still something to share between the two disciplines? For sure, a couple of concepts (mostly, simple emerging properties, e.g., the impact of biodiversity on resistance and resilience of an ecosystem, migration patterns, dependencies along the trophic chain,...) or tools (dendrograms, specialized multivariate analyses, biodiversity or interaction metrics,...) could be of inspiration to software engineers.

Yet, a much deeper consideration is whether the driving force of competition and selection of the fittest, which is so powerful for the evolution of biological ecosystems, could change somehow strategies for software design and evolution. I will discuss this question and propose a couple of ideas in this direction. They will, for sure, look strange in current views. For instance, why did a so badly designed language like R (Morandat et al 2012) become one of the most efficient tools for data analysis? Would a meta-software, able to translate one practical problem into different implementations and learn from their comparisons, change the design of software building blocks? Would the concept of phenotypes (same organism, understand software, but totally different appearance and properties depending on the environment) lead to computer tools that are better tailored for each user than the current ones?

Ultimately, all these ideas converge towards more freedom for self-organisation of software and software ecosystems than is currently the case. Are you, software engineers, ready to learn from living organisms and to loose a little bit of your orchestration power? Are you ready to become a little bit more observers and a little bit less architects? New and interesting emergent properties may well appear from that freedom you would accept to concede to your complex systems!

The Vision of Software Clone Management: Past, Present and the Future

Duplicated code or code clones are a kind of code smells that have both positive and negative impact on the development and maintenance of software systems. Software clone research in the past mostly focused on the detection and analysis of code clones, while the research in recent years indicates that clone management is taking the centre stage due to its pragmatic importance.

Over more than a decade of research on software clones, notably three surveys appeared in the literature, which cover the detection, analysis, and evolutionary characteristics of code clones. In this vision keynote talk we will present a comprehensive survey on the state of the art in clone management, with in-depth investigation of clone management activities such as tracing, refactoring and cost-benefit analysis beyond the detection and analysis. This is the first survey on clone management, where we point to the achievements so far, and reveal avenues for further research necessary towards an integrated clone management system. We will show that while clone detection seems to be a mature research area, there is much to do in managing clones.

Mitigating the Risk of Software Change in Advance. 

Retrospective on more than 50 Architecture Evaluations in Industry

Architecture evaluation has become a mature instrument to make decisions about software systems, assess and mitigate risks, and to identify ways for improvement and migration of software systems. While scientific literature on approaches is available, publications on practical experiences are rather limited. In this paper, we share our experiences - after having performed more than 50 architecture evaluations for industrial customers in the last decade. We compiled facts and consolidate our findings about architecture evaluations in industry and especially highlight the role of reverse engineering in these projects. We share our lessons learned and provide data on common believes and provide examples for common misconceptions on the power of reverse engineering. 

Architecture evaluation is both effective and efficient: effective as it is based on abstractions of the system under evaluation and efficient as it can always focus only on those facts that are relevant to answer the questions at hand. We conducted more than 50 architecture evaluations for industry customers at Fraunhofer IESE (an applied research institute for software engineering located in Kaiserslautern, Germany), where at least one of the authors has been directly or indirectly involved. These projects covered a large number of different types of systems, of industries involved, of evaluation questions asked, and of course a whole spectrum of different evaluation results. The contribution of this paper is to present our experiences together with context factors, empirical data, and lessons learned. On the one hand, we aim at encouraging practitioners to conduct architecture evaluations by showing their impact and lowering the hurdles to making first attempts on their own. On the other hand, we aim at giving researchers insight into industrial architecture evaluations, which can serve as a basis to guide research in this area.
