Download or read book Configurable Software Performance Completions through Higher Order Model Transformations written by Happe, Lucia and published by KIT Scientific Publishing. This book was released on 2014-11-26 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chillies is a novel approach for variable model transformations closing the gap between abstract architecture models, used for performance prediction, and required low-level details. We enable variability of transformations using chain of generators based on the Higher-Order Transformation (HOT). HOTs target different goals, such as template instantiation or transformation composition. In addition, we discuss state-dependent behavior in prediction models and quality of model transformations.

Download or read book Model Transformation Languages with Modular Information Hiding written by Rentschler, Andreas and published by KIT Scientific Publishing. This book was released on 2015-04-13 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model transformations, together with models, form the principal artifacts in model-driven software development. Industrial practitioners report that transformations on larger models quickly get sufficiently large and complex themselves. To alleviate entailed maintenance efforts, this thesis presents a modularity concept with explicit interfaces, complemented by software visualization and clustering techniques. All three approaches are tailored to the specific needs of the transformation domain.

Download or read book Implicit Incremental Model Analyses and Transformations written by Hinkel, Georg and published by KIT Scientific Publishing. This book was released on 2021-07-20 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: When models of a system change, analyses based on them have to be reevaluated in order for the results to stay meaningful. In many cases, the time to get updated analysis results is critical. This thesis proposes multiple, combinable approaches and a new formalism based on category theory for implicitly incremental model analyses and transformations. The advantages of the implementation are validated using seven case studies, partially drawn from the Transformation Tool Contest (TTC).

Download or read book Building Transformation Networks for Consistent Evolution of Interrelated Models written by Klare, Heiko and published by KIT Scientific Publishing. This book was released on 2022-03-24 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex software systems are described with multiple artifacts, such as code, design diagrams and others. Ensuring their consistency is crucial and can be automated with transformations for pairs of artifacts. We investigate how developers can combine independently developed and reusable transformations to networks that preserve consistency between more than two artifacts. We identify synchronization, compatibility and orchestration as central challenges, and we develop approaches to solve them.

Book excerpt: In this book, we introduce an automatic, experiment-based approach for performance problem diagnostics in enterprise software systems. The proposed approach systematically searches for root causes of detected performance problems by executing series of systematic performance tests. The presented approach is evaluated by various case studies showing that the presented approach is applicable to a wide range of contexts.

This book was released on 2022-07-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die modellbasierte Performancevorhersage ist ein bekanntes Konzept zur Gewährleistung der Softwarequalität. Derzeitige Ansätze basieren auf einem Modell mit einer Metrik, was zu ungenauen Vorhersagen für moderne Architekturen führt. In dieser Arbeit wird ein Multi-Strategie-Ansatz zur Erweiterung von Performancevorhersagemodellen zur Unterstützung von Multicore-Architekturen vorgestellt, in Palladio implementiert und dadurch die Genauigkeit der Vorhersage deutlich verbessert. - Model-based performance prediction is a well-known concept to ensure the quality of software. Current approaches are based on a single-metric model, which leads to inaccurate predictions for modern architectures. This thesis presents a multi-strategies approach to extend performance prediction models to support multicore architectures. We implemented the strategies into Palladio and significantly increased the performance prediction power.

Download or read book Deriving Goal oriented Performance Models by Systematic Experimentation written by Westermann, Dennis and published by KIT Scientific Publishing. This book was released on 2014-04-10 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance modelling can require substantial effort when creating and maintaining performance models for software systems that are based on existing software. Therefore, this thesis addresses the challenge of performance prediction in such scenarios. It proposes a novel goal-oriented method for experimental, measurement-based performance modelling. We validated the approach in a number of case studies including standard industry benchmarks as well as a real development scenario at SAP.

Download or read book Automated Improvement of Software Architecture Models for Performance and Other Quality Attributes written by Koziolek, Anne and published by KIT Scientific Publishing. This book was released on 2014-01-07 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality attributes, such as performance or reliability, are crucial for the success of a software system and largely influenced by the software architecture. Their quantitative prediction supports systematic, goal-oriented software design and forms a base of an engineering approach to software design. This thesis proposes a method and tool to automatically improve component-based software architecture (CBA) models based on such quantitative quality prediction techniques.

This book was released on 2018-04-06 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previously, software architects were unable to effectively and efficiently apply reusable knowledge (e.g., architectural styles and patterns) to architectural analyses. This work tackles this problem with a novel method to create and apply templates for reusable knowledge. These templates capture reusable knowledge formally and can efficiently be integrated in architectural analyses.

This book was released on 2022-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing variable systems faces many challenges. Dependencies between interrelated artifacts within a product variant, such as code or diagrams, across product variants and across their revisions quickly lead to inconsistencies during evolution. This work provides a unification of common concepts and operations for variability management, identifies variability-related inconsistencies and presents an approach for view-based consistency preservation of variable systems.
