Book Description
Inhaltsangabe:Abstract: Nowadays, database management systems (DBMS) play a central role in the realization of modern information systems for efficient storage, management and retrieval of large amount of data. At the same time, the eXtensible Markup Language (XML) is emerging fast as de facto standard for electronic data exchange. In order to be able to benefit from both technologies, a number of approaches have already been developed, aiming at the integration of XML and DBMS. They allow processing XML data on the basis of declarative query languages, don t pay however much attention to the manipulation of XML data. The objective of this diploma thesis is to implement X-Ray QL, a declarative query and data manipulation language for X-Ray, an integration approach using the idea of a meta database. X-Ray QL allows besides creating, editing and deleting XML data in a declarative way, to retrieve the XML data using simple select queries. The implementation of X-Ray QL consequently provides an operative runtime part of the X-Ray architecture with features like session management, authorisation mechanism and transaction control. An additional Web Service demonstrates the practical use of the X-Ray QL implementation. Zusammenfassung: Datenbankmanagementsysteme (DBMS) spielen heutzutage eine zentrale Rolle bei der Realisierung moderner Informationssysteme zur effizienten Speicherung, Verwaltung und Verarbeitung großer Datenmengen. Gleichzeitig steht mit der eXtensible Markup Language (XML) eine erweiterbare Auszeichnungssprache zur Verfügung, die unter anderem als Quasi-Standard für den elektronischen Datenaustausch gilt. Um die Vorteile beider Technologien nutzen zu können, existiert bereits eine Reihe von Ansätzen, die eine Integration von XML und DBMS zum Ziel haben. Diese Ansätze erlauben es XML Datenbestände auf Basis deklarativer Abfragesprachen zu verarbeiten, jedoch wurde das Verändern von bestehenden Datenbeständen noch nicht genauer behandelt ([KIM02]). Ziel dieser Diplomarbeit ist es X-Ray QL, eine deklarative Abfrage- und Datenmanipulationssprache für X-Ray, ein Integrationsansatz unter Verwendung einer Metadatenbank, zu implementieren. X-Ray QL ermöglicht, neben dem deklarativen Erzeugen, Ändern und Löschen von XML Datenbeständen, auch einfache Abfragen durchzuführen. Durch die Implementierung von X-Ray QL entsteht der Laufzeitteil der X-Ray Architektur, welcher sich durch Sessionmanagement, Autorisierungsmechanismus und [...]

Data Provenance

Data Provenance PDF Author: Boris Glavic
Publisher:
ISBN: 9781680838299
Category : Database management
Languages : en
Pages :

Book Description
The term provenance is used in the art world to describe a record of the history of ownership of a piece of art. This term has been adapted by the database community to describe a record of the origin of a piece of data. Data provenance emerged as a research topic in the database community in the late 1990s. Data provenance, by explaining how the result of an operation was derived from its inputs, has proven to be a useful tool that is applicable in a wide variety of applications. This monograph gives a comprehensive introduction to data provenance concepts, algorithms, and methodology developed in the last few decades. It introduces the reader to the formalisms, algorithms, and system's developments in this fascinating field as well as providing a collection of relevant literature references for further research. The monograph provides a concise starting point for research into and using provenance in data. Although focusing on data provenance in databases pointers to work in other fields are given throughout. The intended audience is researchers and practitioners unfamiliar with the topic who want to develop a basic understanding of provenance techniques and the state-of-the-art in the field as well as researchers with prior experience in provenance that want to broaden their horizon.

Refinement Types

Refinement Types PDF Author: Ranjit Jhala
Publisher:
ISBN: 9781680838848
Category : Computers
Languages : en
Pages : 182

Book Description
Refinement types can be the vector that brings formal verification into mainstream software development. This happy outcome hinges upon the design and implementation of refinement type systems that can be retrofitted to existing languages, or co-designed with new ones.In this book, the authors catalyze the development of such systems by distilling the ideas developed in the sprawling literature on the topic into a coherent and unified tutorial that explains the key ingredients of modern refinement type systems, by showing how to implement a refinement type checker.Inspired by the nanopass framework for teaching compilation the authors show how to implement refinement types via a progression of languages that incrementally add features to the language or type system.The readily accessible book provides the reader with an insightful introduction into Refinement Types using an innovative tutorial style that enables fast learning. Furthermore, the accompanying software implementation allows readers to work on practical real-world examples.
