abstract = {Most enterprises have a diverse environment of heterogeneous and autonomous
information systems. If the same data is relevant for several information
systems, then data changes in one supplier system affect data stored in other
demander systems. The process of exchanging changed data between systems, named
change propagation, is based on dependencies established between these systems.
The management of a single, integrated enterprise information system is often
infeasible or too expensive, due to the autonomy of business units and the
heterogeneity of their IT infrastructures. The solution is to support the
enterprise by a generic approach able to manage data dependencies and to
transform data stored in a source information system into data stored in the
dependent information systems. We propose a loosely coupled system, called
Stuttgart Information and Exploration System. Our prototype mainly consists of
a data dependency specification tool, a propagation engine and a repository
that stores all relevant objects for these components.},

abstract = {RAMSES is one of the first large-scale prototypes of an operational Earth
Observation (EO) application system. It implements a complex infrastructure for
the extensive support of a thematic EO application system, which focuses on the
detection and monitoring of oil spills. Since EO application systems are
usually built on top of a set of generic functions, this paper analyses and
assesses the RAMSES infrastructure in order to form a generic EO application
framework. This framework should mainly support the collaborative development
and customization of emerging EO application systems by maximizing the use of
already existing system facilities. Furthermore, it should support the flexible
extension and rapid reconfiguration of workflows as the business changes.
Results of our analyses show that the RAMSES infrastructure does not cover all
requirements of an EO application framework. We therefore introduce advanced
design concepts and propose a new framework architecture that structurally
controls the inherent complexity of the interdisciplinary domain of EO
application systems.},

systems are important for today's increasingly heterogeneous enterprise IT
infrastructures. Updates, insertions, and deletions of data objects in
autonomous information systems often have to trigger data changes in other
autonomous systems, even if the distributed systems are not integrated into a
global schema. We suggest a solution to this problem based on the propagation
and transformation of data using several XML technologies. Our prototype
manages dependencies between the schemas of distributed data sources and allows
to define and process arbitrary actions on changed data by manipulating all
dependent data sources. The prototype comprises a propagation engine that
interprets scripts based on a workflow specification language, a data
dependency specification tool, a system administration tool, and a repository
that stores all relevant information for these tools.},

abstract = {Algorithms for finding frequent itemsets fall into two broad classes: (1)
algorithms that are based on non-trivial SQL statements to query and update a
database, and (2) algorithms that employ sophisticated in-memory data
structures, where the data is stored into and retrieved from flat files. Most
performance experiments have shown that SQL-based approaches are inferior to
main-memory algorithms. However, the current trend of database vendors to
integrate analysis functionalities into their query execution and optimization
components, i.e., ``closer to the data,'' suggests revisiting these results and
searching for new, potentially better solutions.
We investigate approaches based on SQL-92 and present a new approach called
Quiver that employs universal and existential quantifications. This approach
uses a table layout for itemsets, where a group of multiple records represents
a single itemset. Hence, our vertical layout is similar to the popular layout
used for the transaction table, which is the input of frequent itemset
discovery. Our approach is particularly beneficial if the database system in
use provides adequate strategies and techniques for processing universally
quantified queries, unlike current commercial systems.},

abstract = {Today, it is common that enterprises manage several mostly heterogeneous
information systems to supply their production and business processes with
data. There is a need to exchange data between the information systems while
preserving system autonomy. Hence, an integration approach that relies on a
single global en-terprise data schema is ruled out. This is also due to the
widespread usage of legacy systems. We propose a system, called Propagation
Manager, which manages dependencies between data objects stored in different
information systems. A script specifying complex data transformations and other
sophisticated activities, like the execution of external programs, is
associated with each dependency. For example, an object update in a source
system can trigger data transformations of the given source data for each
destination system that depends on the object. Our system is implemented using
current XML technologies. We present the archi-tecture and processing model of
our system and demonstrate the benefit of our approach by illustrating an
extensive example scenario.},

abstract = {Queries containing universal quantification are used in many applications,
including business intelligence applications. Several algorithms have been
proposed to implement universal quantification efficiently. These algorithms
are presented in an isolated manner in the research literature - typically, no
relationships are shown between them. Furthermore, each of these algorithms
claims to be superior to others, but in fact each algorithm has optimal
performance only for certain types of input data. In this paper, we present a
comprehensive survey of the structure and performance of algorithms for
universal quantification. We introduce a framework for classifying all possible
kinds of input data for universal quantification. Then we go on to identify the
most efficient algorithm for each such class. One of the input data classes has
not been covered so far. For this class, we propose several new algorithms. For
the first time, we are able to identify the optimal algorithm to use for any
given input dataset. These two classifications of input data and optimal
algorithms are important for query optimization. They allow a query optimizer
to make the best selection when optimizing at intermediate steps for the
quantification problem.},
