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 [...]

Book Description
This book offers a comprehensive introduction to relational (SQL) and non-relational (NoSQL) databases. The authors thoroughly review the current state of database tools and techniques, and examine coming innovations. The book opens with a broad look at data management, including an overview of information systems and databases, and an explanation of contemporary database types: SQL and NoSQL databases, and their respective management systems The nature and uses of Big Data A high-level view of the organization of data management Data Modeling and Consistency Chapter-length treatment is afforded Data Modeling in both relational and graph databases, including enterprise-wide data architecture, and formulas for database design. Coverage of languages extends from an overview of operators, to SQL and and QBE (Query by Example), to integrity constraints and more. A full chapter probes the challenges of Ensuring Data Consistency, covering: Multi-User Operation Troubleshooting Consistency in Massive Distributed Data Comparison of the ACID and BASE consistency models, and more System Architecture also gets from its own chapter, which explores Processing of Homogeneous and Heterogeneous Data; Storage and Access Structures; Multi-dimensional Data Structures and Parallel Processing with MapReduce, among other topics. Post-Relational and NoSQL Databases The chapter on post-relational databases discusses the limits of SQL – and what lies beyond, including Multi-Dimensional Databases, Knowledge Bases and and Fuzzy Databases. A final chapter covers NoSQL Databases, along with Development of Non-Relational Technologies, Key-Value, Column-Family and Document Stores XML Databases and Graphic Databases, and more The book includes more than 100 tables, examples and illustrations, and each chapter offers a list of resources for further reading. SQL & NoSQL Databases conveys the strengths and weaknesses of relational and non-relational approaches, and shows how to undertake development for big data applications. The book benefits readers including students and practitioners working across the broad field of applied information technology. This textbook has been recommended and developed for university courses in Germany, Austria and Switzerland.

Book Description
For over 25 years, C. J. Dates An Introduction to Database Systems has been the authoritative resource for readers interested in gaining insight into and understanding of the principles of database systems. This exciting revision continues to provide a solid grounding in the foundations of database technology and to provide some ideas as to how the field is likely to develop in the future. The material is organized into six major parts. Part I provides a broad introduction to the concepts of database systems in general and relational systems in particular. Part II consists of a careful description of the relational model, which is the theoretical foundation for the database field as a whole. Part III discusses the general theory of database design. Part IV is concerned with transaction management. Part V shows how relational concepts are relevant to a variety of further aspects of database technology-security, distributed databases, temporal data, decision support, and so on. Finally, Part VI describes the impact of object technology on database systems. This Seventh Edition of An Introduction to Database Systems features widely rewritten material to improve and amplify treatment o
