abstract = {One of the major challenges for Enterprise Application Integration (EAI)
process modeling tools is the continuous adaptation of the business processes
and services. Business and IT specialists are both confronted with a number of
problems involved in the adaptation of such processes, such as the lack of
support for process lifecycle management, data and functional interoperability
problems or the appropriate service knowledge base. Currently, most service
engineering methods adopt a lifecycle strategy for the design, implementation,
deployment and evaluation of services. However, enterprises exploiting service
reusability lack the knowledge on process dependencies across the entire
service lifecycle. This knowledge is required by process modeling tools in
order to keep EAI processes loosely-coupled. Using a provenance data model we
describe the different types of service dependencies in EAI processes with
regard to the service changes across its lifecycle. We present a
provenance-aware service repository with provenance subscription capabilities
and its adoption for different use cases in the manufacturing domain.},

abstract = {Nowadays, many applications processes stream-based data, such as financial
market analysis, network intrusion detection, or visualization applications. To
process stream-based data in an applicationindependent manner, distributed
stream processing systems emerged. They typically translate a query to an
operator graph, place the operators to stream processing nodes, and execute
them to process the streamed data. The operator placement is crucial in such
systems, as it deeply influences query execution. Often, different stream-based
applications require dedicated placement of query graphs according to their
specific objectives, e.g. bandwidth not less than 500 MBit/s and costs not more
that 1 cost unit. This fact constraints operator placement. Existing approaches
do not take into account application-specific objectives, thus not reflecting
application-specific placement decisions. As objectives might conflict among
each other, operator placement is subject to delicate trade-offs, such as
bandwidth maximization is more important than cost reduction. Thus, the
challenge is to find a solution which considers the application-specific
objectives and their trade-offs.
We present M-TOP, an QoS-aware multi-target operator placement framework for
data stream systems. Particularly, we propose an operator placement strategy
considering application-specific targets consisting of objectives, their
respective trade-offs specifications, bottleneck conditions, and ranking
schemes to compute a suitable placement. We integrated M-TOP into NexusDS, our
distributed data stream processing middleware, and provide an experimental
evaluation to show the effectiveness of M-TOP.},

abstract = {Techniques for efficient and distributed processing of huge, unbound data
streams have made some impact in the database community. Distributed data
stream processing systems have emerged providing a distributed environment to
process these potentially unbound streams of data by a set of processing nodes.
A wide range of realtime applications process stream-based data. Sensors and
data sources, such as position data of moving objects, continuously produce
data that is consumed by, e.g., location-aware applications. Depending on the
domain of interest, the processing of such data often depends on
domain-specific functionality. For instance, an application which visualizes
stream-based data has stringent timing constraints, or may even need a specific
hardware environment to smoothly process the data. Furthermore, users may add
additional constraints. E.g., for security reasons they may want to restrict
the set of nodes that participates in processing.
In this paper we review context-aware applications which, despite their
different application fields, share common data processing principles. We
analyse these applications and extract common requirements which data stream
processing systems must meet to support these applications. Finally, we show
how such applications are implemented using NexusDS, our extensible stream
processing middleware.},

control- and fieldbus systems as well as the extensive testing of functions.
This paper presents an approach based on a service- oriented architecture (SOA)
to automate the start-up of a reconfigurable production machine. Functionality
for configuration and start-up is provided by an internal middleware system.
The sequence control for the startup process is realised within a configuration
system. A new approach to the combination of field-bus and middleware
communication infrastructure is used to adopt SOA paradigms to existing
automation technology. Thus, real-time communication can be combined with
flexible communication for the automatic configuration of production machines.},

abstract = {The W3C Resource Description Framework (RDF) is gaining popularity for its
ability to manage semi-structured data without a predefined database schema. So
far, most RDF query processors have concentrated on finding complex graph
patterns in RDF, which typically involves a high number of joins. This works
very well to query resources by the relations between them. Yet, obtaining a
record-like view on the attributes of resources, as natively supported by
RDBMS, imposes unnecessary performance burdens, as the individual attributes
must be joined to assemble the final result records.
We present an approach to retrieve the attributes of resources efficiently. We
first determine the resources in question and then retrieve all their
attributes efficiently at once, exploiting contiguous storage in RDF indexes.
In addition, we present an index structure which is specifically designed for
RDF attribute retrieval. In a performance evaluation we show that our approach
is clearly superior for larger numbers of retrieved attributes.},

abstract = {Integration efforts in today’s manufacturing environments tend to enable
service-based communication interfaces between enterprise and manufacturing
systems. Constantly changing business conditions demand a high level of
flexibility in business processes as well as an adaptive and fully
interoperable IT infrastructure. The principles of reusability and
loosely-coupled services have driven Service Oriented Architecture (SOA) to
become the most used paradigm for software design at the business level. In a
manufacturing environment, event-driven architectures (EDA) are often employed
for managing information flows across different production systems. The timely
propagation of business-relevant events is a fundamental requirement in
Engineer-to-Order (ETO) enterprises, which require a high level of transparency
in their supply chains. Agility is one of the top priorities for ETO
manufacturers in order to react to turbulent scenarios. Therefore, the main
challenge for ETO supply chains is to identify and propagate events across the
ETO logistics network and integrate these into the manufacturer business
processes. We present how an existing service-oriented integration platform for
manufacturing can be used to fill the gap between EDA-based manufacturing
environments of an ETO supply chain and SOA-based manufacturer business
processes. In this paper, we discuss the benefits of the Business Process
Execution Language (BPEL) as vehicle for this integration. The adoption of BPEL
will enable an efficient and effective reaction to turbulent manufacturing
scenarios in an ETO supply chain.},

priori optimal w.r.t. the goal(s) of the business owning the process. Process

process is often less than optimal. This is due to two major challenges: First,
since the design is an a priori ability, no actual execution data is available
to provide the foundations for design decisions. Second, since modeling
decision support is typically basic at best, the quality of the design largely
depends on the ability of business analysts to make the ”right” design choices.
To address these challenges, we present in this paper our deep Business
Optimization Platform that enables (semi-) automated process optimization

this task by matching new processes to existing processes stored in a

abstract = {The success of most of today's businesses is tied to the efficiency and
effectiveness of their core processes. Yet, two major challenges often prevent
optimal processes: First, the analysis techniques applied during the
optimization are inadequate and fail to include all relevant data sources.
Second, the success depends on the abilities of the individual analysts to spot
the right designs amongst a plethora of choices. Our deep Business Optimization
Platform addresses these challenges through specialized data integration,
analysis and optimization facilities. In this paper, we focus on how it uses
formalized process optimization patterns for detecting and implementing process
improvements.},

abstract = {Location-based services (LBS) have gained tremendous popularity with millions
of simultaneous users daily. LBS handle very large data volumes and face
enormous query loads. Both the data and the queries possess high locality:
spatial data is distributed very unevenly around the globe, query load is
different throughout the day, and users often search for similar things in the
same places. This causes high load peaks at the data tier of LBS, which may
seriously degrade performance. To cope with these load peaks, we present DiSCO,
a distributed semantic cache overlay for LBS. DiSCO exploits the spatial,
temporal and semantic locality in the queries of LBS and distributes frequently
accessed data over many nodes. Based on the Content-Addressable Network (CAN)
peer-to-peer approach, DiSCO achieves high scalability by partitioning data
using spatial proximity. Our evaluation shows that DiSCO significantly reduces
queries to the underlying data tier.},

abstract = {Mobile devices have become general-purpose computers that are equipped with
sensors, constantly access the internet, and almost always accompany the user.
Consequently, devices manage many different kinds of data about the user's life
and context. There is considerable overlap in this data, as different
applications handle similar data domains. Applications often keep this data in
separated data silos. Web applications, which manage large amounts of personal
data, hardly share this data with other applications at all. This lack of
interoperability creates redundancy and impacts usability of mobile devices. We
present a data management architecture for mobile devices to support
interoperability between applications, devices and web applications at the data
management level. We propose a central on-device repository for applications to
share resource and context data in an integrated, extensible data model which
uses semantic web technologies and supports location data. A web browser
interface shares data with web applications, as controlled by a general
security model.},

abstract = {Adequate data management and data provisioning are among the most important
topics to cope with the information explosion intrinsically associated with
simulation applications. Today, data exchange with and between simulation
applications is mainly accomplished in a file-style manner. These files show
proprietary formats and have to be transformed according to the specific needs
of simulation applications. Lots of effort has to be spent to find appropriate
data sources and to specify and implement data transformations. In this paper,
we present SIMPL – an extensible framework that provides a generic and
consolidated abstraction for data management and data provisioning in
simulation workflows. We introduce extensions to workflow languages and show
how they are used to model the data provisioning for simulation workflows based
on data management patterns. Furthermore, we show how the framework supports a
uniform access to arbitrary external data in such workflows. This removes the
burden from engineers and scientists to specify low-level details of data
management for their simulation applications and thus boosts their
productivity.},

abstract = {Accessing and processing huge amounts of heterogeneous and distributed data are
some of the major challenges of data-intensive workflows. Traditionally, the
descriptions of such workflows focus on their data flow. Nevertheless,
control-flow-oriented workflow languages are increasingly adapted to the needs
of data-intensive workflows. This provides a common level of abstraction for
both data-intensive workflows and classical orchestration workflows, e.g.,
business workflows, which then enables a comprehensive optimization across all
workflows. However, the problem still remains that workflows described in
control-flow-oriented languages tend to be less efficient for data-intensive
processes compared to specialized data-flow-oriented approaches. In this paper,
we propose a new kind of optimization targeted at data-intensive workflows that
are described in control-flow-oriented languages. We show how to improve
efficiency of such workflows by introducing various techniques that partition
the local data processing tasks to be performed during workflow execution in an
improved way. These data processing tasks are either assigned to the workflow
engine or to the tightly integrated local database engine. We evaluate the
effectiveness of these techniques by means of various test scenarios.},

business processes as well as an adaptive and fully interoperable IT
infrastructure in today’s manufacturing environments. The lack of flexibility
prevents manufacturing companies from improving their responsiveness and
adapting their workflows to turbulent scenarios. In order to achieve highly
flexible and adaptive workflows, information systems in digital factories and
shop floors need to be integrated. The most challenging problem in such
manufacturing environments is the high heterogeneity of the IT landscape, where
the integration of legacy systems and information silos has led to chaotic
architectures over the last two decades. In order to overcome this issue, the
authors present a flexible integration platform that allows a loose coupling of
distributed services in event-driven manufacturing environments. The proposed
approach enables a flexible communication between digital factory and shop
floor components by introducing a service bus architecture. This solution
integrates an application-independent canonical message format for
manufacturing events, content-based routing and transformation services as well
as event processing workflows.},
