This book provides a frequentist semantics for conditionalization on partially known events, which is given as a straightforward generalization of classical conditional probability via so-called probability testbeds. It analyzes the resulting partial conditionalization, called frequentist partial (F.P.) conditionalization, from different angles, i.e., with respect to partitions, segmentation, independence, and chaining. It turns out that F.P. conditionalization meets and generalizes Jeffrey conditionalization, i.e., from partitions to arbitrary collections of events, opening it for reassessment and a range of potential applications. A counterpart of Jeffrey’s rule for the case of independence holds in our frequentist semantics. This result is compared to Jeffrey’s commutative chaining of independent updates.The postulate of Jeffrey's probability kinematics, which is rooted in the subjectivism of Frank P. Ramsey, is found to be a consequence in our frequentist semantics. This way the book creates a link between the Kolmogorov system of probability and one of the important Bayesian frameworks. Furthermore, it shows a preservation result for conditional probabilities under the full update range and compares F.P. semantics with an operational semantics of classical conditional probability in terms of so-called conditional events. Lastly, it looks at the subjectivist notion of desirabilities and proposes a more fine-grained analysis of desirabilities a posteriori.This book appeals to researchers who are involved in any kind of knowledge processing systems. F.P. conditionalization is a straightforward, fundamental concept that fits human intuition, and is systematically linked to one of the important Bayesian frameworks. As such, the book is interesting for anybody investigating the semantics of reasoning systems.

Form-based applications range from simple web shops to complex enterprise resource planning systems. Draheim and Weber adapt well-established basic modeling techniques in a novel way to achieve a modeling framework optimized for this broad application domain. They introduce new modeling artifacts, such as page diagrams and form storyboards, and separate dialogue patterns to allow for reuse. In their implementation they have developed new constructs such as typed server pages, and tools for forward and reverse engineering of presentation layers. The methodology is explained using an online bookshop as a running example in which the user can experience the modeling concepts in action.The combination of theoretical achievements and hands-on practical advice and tools makes this book a reference work for both researchers in the areas of software architectures and submit-response style user interfaces, and professionals designing and developing such applications. More information and additional material is also available online.

TEAA 2005 (Trends in Enterprise Application Architecture) took place as a workshop of the conference VLDB 2005 (31st International Conference on Very Large Databases) in August 2005 in Trondheim, Norway. Enterprise applicationsare mission criticalfor organizations.Currently there are several initiatives that see enterprise application integration as their natural playground, like Model Driven Architecture and Service Oriented Architecture. Now is the time to investigate how these approaches can provide added value. At TEAA 2005 the contributions identi?ed a problem or issue in enterprise application architecture and proposed and evaluated a solution. The workshop bene?ted from lively discussions among the participants. Applications, operating systems, database systems, hardware architecture and system administration concepts must be orchestrated to yield an optimized systemarchitecturethat tacklesperformance,stability,security,maintainability, andtotalcostofownership.Inpractice,itisalwaysaholisticviewthatisneeded – it is known that system design approaches that overemphasize one of the software or hardware architecture aspects are likely to fail. In the TEAA 2005 workshop we examined the conceptual underpinnings of enterprise application architecture. We are grateful to our keynote speaker Laura Haas for sharing her insights with us.

This book constitutes the thoroughly refereed postproceedings of the 2nd International Conference on Trends in Enterprise Application Architecture, TEAA 2006. It identifies issues in enterprise application architecture and proposes as well as evaluates a solution. Topics of interest include model driven architecture, enterprise development environments, service oriented architecture, data integration, enterprise grid computing, load balancing, and enterprise component platforms.

Currently, we see a variety of tools and techniques for specifying and implementing business processes. The problem is that there are still gaps and tensions between the different disciplines needed to improve business process execution and improvement in enterprises. Business process modeling, workflow execution and application programming are examples of disciplines that are hosted by different communities and that emerged separately from each other. In particular, concepts have not yet been fully elaborated at the system analysis level.Therefore, practitioners are faced again and again with similar questions in concrete business process projects: Which decomposition mechanism to use? How to find the correct granularity for business process activities? Which implementing technology is the optimal one in a given situation?This work offers an approach to the systematization of the field. The methodology used is explicitly not a comparative analysis of existing tools and techniques – although a review of existing tools is an essential basis for the considerations in the book. Rather, the book tries to provide a landscape of rationales and concepts in business processes with a discussion of alternatives.

Software is pervasive in today's technical systems in industry and everyday life. Modern enterprises strategically invest into software and often have their own software development departments. Software engineering is the exciting discipline that addresses the challenges of today’s software projects: cost and time pressure and software quality. This book aims at uncovering the implicit assumptions of today’s leading software engineering paradigms. It presents knowledge shared by seasoned experts in the field which is usually gained by experience in software engineering projects or communication between software engineers only. This way, the book wants to empower the ambitious software developer to become the project’s systems thinker and systems strategist by telling the story of successful software engineering projects.

This book takes a foundational approach to the semantics of probabilistic programming. It elaborates a rigorous Markov chain semantics for the probabilistic typed lambda calculus, which is the typed lambda calculus with recursion plus probabilistic choice.The book starts with a recapitulation of the basic mathematical tools needed throughout the book, in particular Markov chains, graph theory and domain theory, and also explores the topic of inductive definitions. It then defines the syntax and establishes the Markov chain semantics of the probabilistic lambda calculus and, furthermore, both a graph and a tree semantics. Based on that, it investigates the termination behavior of probabilistic programs. It introduces the notions of termination degree, bounded termination and path stoppability and investigates their mutual relationships. Lastly, it defines a denotational semantics of the probabilistic lambda calculus, based on continuous functions over probability distributionsas domains.The work mostly appeals to researchers in theoretical computer science focusing on probabilistic programming, randomized algorithms, or programming language theory.
