Cost-Based Optimization of Integration Flows - Datenbanken ...

1 Introduction
violated. We present this concept separately for two reasons: first, the contributions
of Chapters 3-5 are easier to understand using the simple model of periodical reoptimization;
second, although the concept of on-demand re-optimization has been
designed for integration flows, other research fields can also benefit from this general
re-optimization approach.
Finally, Chapter 7 concludes this thesis with a summary of achieved results and a
discussion of open research aspects.

Conclusions
Figure 1.1: Overview of the Structure of this Thesis
In the first part, we give the necessary background in terms of a literature survey.
Subsequently, in the second part, we explain the foundations of periodical cost-based reoptimization
and discuss two integration-flow-specific optimization techniques in detail.
Finally, the third part introduces the advanced concept of on-demand, cost-based reoptimization
and how the presented approaches from Part II benefit from this concept.
