Data warehouses have captured the attention of practitioners and researchers alike. But the design and optimization of data warehouses remains an art rather than a science. This book presents the first comparative review of the state of the art and best current practice of data warehouses. It covers source and data integration, multidimensional aggregation, query optimization, update propagation, metadata management, quality assessment, and design optimization. Also, based on results of the European Data Warehouse Quality project, it offers a conceptual framework by which the architecture and quality of data warehouse efforts can be assessed and improved using enriched metadata management combined with advanced techniques from databases, business modeling, and artificial intelligence. For researchers and database professionals in academia and industry, the book offers an excellent introduction to the issues of quality and metadata usage in the context of data warehouses.

Schmidt and Bannon (1992) introduced the concept of common
information space by contrasting it with technical conceptions of
shared information: Cooperative work is not facilitated simply by
the provisioning of a shared database, but rather requires the
active construction by the participants of a common information
space where the meanings of the shared objects are debated and
resolved, at least locally and temporarily. (Schmidt and Bannon, p.
22) A CIS, then, encompasses not only the information but also the
practices by which actors establish its meaning for their
collective work. These negotiated understandings of the information
are as important as the availability of the information itself: The
actors must attempt to jointly construct a common information space
which goes beyond their individual personal information spaces. . .
. The common information space is negotiated and established by the
actors involved. (Schmidt and Bannon, p. 28) This is not to suggest
that actors' understandings of the information are identical; they
are simply "common" enough to coordinate the work. People
understand how the information is relevant for their own work.
Therefore, individuals engaged in different activities will have
different perspectives on the same information. The work of
maintaining the common information space is the work that it takes
to balance and accommodate these different perspectives. A "bug"
report in software development is a simple example. Software
developers and quality assurance personnel have access to the same
bug report information. However, access to information is not
sufficient to coordinate their work.

This book constitutes the proceedings of 26th International
Conference on Advanced Information Systems Engineering, CAiSE 2014,
held in Thessaloniki, Greece in June 2014. The 41 papers and 3
keynotes presented were carefully reviewed and selected from 226
submissions. The accepted papers were presented in 13 sessions:
clouds and services; requirements; product lines; requirements
elicitation; processes; risk and security; process models; data
mining and streaming; process mining; models; mining event logs;
databases; software engineering.
Information systems are large repositories of factual and
inferential knowledge intended to be queried and maintained by a
wide variety of users with different backgrounds and work tasks.
The community of potential information system users is growing
rapidly with advances in hardware and software technology that
permit computer/communications support for more and more
application areas. Unfortunately, it is often felt that progress in
user interface technology has not quite matched that of other
areas. Technical solutions such as computer graphics, natural
language processing, or man-machine-man communications in office
systems are not enough by themselves. They should be complemented
by system features that ensure cooperative behavior of the
interfaces, thus reducing the training and usage effort required
for successful interaction. In analogy to a human dialog partner,
we call an interface cooperative if it does not just accept user
requests passively or answer them literally, but actively attempts
to understand the users' intentions and to help them solve their
applica tion problems. This leads to the central question addressed
by this book: What makes an information systems interface
cooperative, and how do we provide capabilities leading to
cooperative interfaces? Many answers are possible. A first aspect
concerns the formulation and accep tance of user requests. Many
researchers assume that such requests should be formulated in
natural language."

CAiSE*99 is the 11th in the series of International Conferences on
Advanced Information Systems Engineering. The aim of the CAiSE
series is to give - searchers and professionals from universities,
research, industry, and public - ministrationthe opportunityto
meetannuallytodiscussevolvingresearchissues and applications in the
el d of information systems engineering; also to assist young
researchersand doctoralstudents in establishing relationships with
senior scientists in their areas of interest.
StartingfromaScandinavianorigininthelate1980 s, CAiSEhasevolvedinto
atrulyinternationalconferencewithaworldwideauthorandattendancelist.The
CAiSE*99 programlisted contributions from 19 countries, from four
continents These contributions, 27 full papers, 12 short research
papers, six workshops, and four tutorials, were carefully selected
from a total of 168 submissions by the international program
committee. A special theme of CAiSE*99 was Component-based
information systems engineering . Component-based approaches mark
the maturity of any engine- ing discipline. However,
transferingthis idea to the complex anddiverse worldof information
systems has proven more di cult than expected. Despite numerous
proposals from object-oriented programming, design patterns and
frameworks, customizable reference models and standard software,
requirements engine- ing and business re-engineering, web-based
systems, data reduction strategies, knowledge management, and
modularized education, the question of how to make
component-oriented approaches actually work in information systems
- mains wide open."
The fourth international conference on Extending Data Base
Technology was held in Cambridge, UK, in March 1994. The biannual
EDBT has established itself as the premier European database
conference. It provides an international forum for the presentation
of new extensions to database technology through research,
development, and application. This volume contains the scientific
papers of the conference. Following invited papers by C.M. Stone
and A. Herbert, it contains 31 papers grouped into sections on
object views, intelligent user interface, distributed information
servers, transaction management, information systems design and
evolution, semantics of extended data models, accessing new media,
join algorithms, query optimization, and multimedia databases.
In the early 1980s, a trend towards formal undeIStanding and
knowledge-based assistance for the development and maintenance of
database-intensive information systems became apparent. The group
of John Mylopoulos at the UniveISity of Toronto and their European
collaboratoIS moved from semantic models of information systems
design (Taxis project) towards earlier stages of the software
lifecycle. Joachim Schmidt's group at the University of Hamburg
completed their early work on the design and implementation of
database programming languages (Pascal/R) and began to consider
tools for the development of large database program packages. The
Belgian company BIM developed a fast commercial Prolog which turned
out to be useful as an implementation language for object oriented
knowledge representation schemes and as a prototyping tool for
formal design models. Case studies by Vasant Dhar and Matthias
Jarke in New York pointed out the need for formally representing
process knowledge, and a number of projects in the US and Europe
began to consider computer assistance (CASE) as a viable approach
to support software engineering. In 1985, the time appeared ripe
for an attempt at integrating these experiences in a comprehensive
CASE framework relating all phases of an information systems
lifecycle. The Commission of the European Communities decided in
early 1986 to fund this joint effort by six European software
houses and research institutions in the Software Technology section
of the ESPRIT I program. The project was given the number 892 and
the title DAIDA - Development Assistance for Intelligent Database
Applications."
