ETL workflows populate those systems with data from various data sources by specifying and executing a DAG of transformations. Over time, hundreds of individual workflows evolve as new sources and new requirements are integrated into the system. The maintenance and evolution of large-scale ETL systems requires much time and manual effort. A key problem is to understand the meaning of unfamiliar attribute labels in source and target databases and ETL transformations. Hard-to-understand attribute labels lead to frustration and time spent to develop and understand ETL workflows. We present a schema decryption technique to support ETL developers in understanding cryptic schemata of sources, targets, and ETL transformations. For a given ETL system, our recommender-like approach leverages the large number of mapped attribute labels in existing ETL workflows to produce good and meaningful decryptions. In this way we are able to decrypt attribute labels consisting of a number of unfamiliar few-letter abbreviations, such as UNP_PEN_INT, which we can decrypt to UNPAID_PENALTY_INTEREST. We evaluate our schema decryption approach on three real-world repositories of ETL workflows and show that our approach is able to suggest high-quality decryptions for cryptic attribute labels in a given schema.}, language = {en} } @book{AppeltauerHirschfeld2012, author = {Appeltauer, Malte and Hirschfeld, Robert}, title = {The JCop language specification : Version 1.0, April 2012}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-193-6}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-60208}, publisher = {Universit{\"a}t Potsdam}, pages = {iv, 48}, year = {2012}, abstract = {Program behavior that relies on contextual information, such as physical location or network accessibility, is common in today's applications, yet its representation is not sufficiently supported by programming languages. With context-oriented programming (COP), such context-dependent behavioral variations can be explicitly modularized and dynamically activated. In general, COP could be used to manage any context-specific behavior. However, its contemporary realizations limit the control of dynamic adaptation. This, in turn, limits the interaction of COP's adaptation mechanisms with widely used architectures, such as event-based, mobile, and distributed programming. The JCop programming language extends Java with language constructs for context-oriented programming and additionally provides a domain-specific aspect language for declarative control over runtime adaptations. As a result, these redesigned implementations are more concise and better modularized than their counterparts using plain COP. JCop's main features have been described in our previous publications. However, a complete language specification has not been presented so far.

In the last years conditional dependencies have been introduced to analyze and improve data quality. In short, a conditional dependency is a dependency with a limited scope defined by conditions over one or more attributes. Only the matching part of the instance must adhere to the dependency. In this paper we focus on conditional inclusion dependencies (CINDs). We generalize the definition of CINDs, distinguishing covering and completeness conditions. We present a new use case for such CINDs showing their value for solving complex data quality tasks. Further, we define quality measures for conditions inspired by precision and recall. We propose efficient algorithms that identify covering and completeness conditions conforming to given quality thresholds. Our algorithms choose not only the condition values but also the condition attributes automatically. Finally, we show that our approach efficiently provides meaningful and helpful results for our use case.}, language = {en} } @book{BauerMuehlJaeckelBeckeretal.2012, author = {Bauer, Hartmut and M{\"u}hl-J{\"a}ckel, Margarete and Becker, Ulrich and Br{\"u}ning, Christoph and Sch{\"a}fer, Roland and R{\"o}ber, Manfred and Kunze, Sebastian}, title = {Rekommunalisierung {\"o}ffentlicher Daseinsvorsorge}, editor = {Bauer, Hartmut and B{\"u}chner, Christiane and Hajasch, Lydia}, publisher = {Universit{\"a}tsvlerag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-170-7}, issn = {1867-9528}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-58064}, publisher = {Universit{\"a}t Potsdam}, pages = {109}, year = {2012}, abstract = {Mehr Privat statt Staat!

A particular challenging case are systems where these cyber-physical systems are formed ad hoc according to the specific local topology, the available networking capabilities, and the goals and constraints of the subsystems captured by the information processing part. In this paper we present a formalism that permits to model the sketched class of cyber-physical systems. The ad hoc formation of tightly coupled subsystems of arbitrary size are specified using a UML-based graph transformation system approach. Differential equations are employed to define the resulting tightly coupled behavior. Together, both form hybrid graph transformation systems where the graph transformation rules define the discrete steps where the topology or modes may change, while the differential equations capture the continuous behavior in between such discrete changes. In addition, we demonstrate that automated analysis techniques known for timed graph transformation systems for inductive invariants can be extended to also cover the hybrid case for an expressive case of hybrid models where the formed tightly coupled subsystems are restricted to smaller local networks.}, language = {en} } @book{BeckmannvanderBliekBrandstetteretal.2012, author = {Beckmann, Susanne and van der Bliek, Arjan and Brandstetter, Gabriele and Haase, Birgit and de la Haye, Amy and Honnef, Klaus and K{\"u}hl, Alicia and Leutner, Petra and Lindemann, Uwe and Martens, Olaf and Mentges, Gabriele and Rasche, Adelheid and Silbermann, Charlotte and S{\"o}ll, {\"A}nne and Tietze, Katharina and Waidenschlager, Christine and Weise, Katja}, title = {R{\"a}ume der Mode}, editor = {Lehnert, Gertrud}, publisher = {Fink}, address = {Paderborn}, isbn = {978-3-7705-5200-9}, pages = {293 S.}, year = {2012}, language = {de} }
