  • Declarative Access to Filesystem Data New Application Domains for XML Database Management Systems
    Declarative Access to Filesystem Data New application domains for XML database management systems Alexander Holupirek Dissertation zur Erlangung des akademischen Grades Doktor der Naturwissenschaften (Dr. rer. nat.) Fachbereich Informatik und Informationswissenschaft Mathematisch-Naturwissenschaftliche Sektion Universität Konstanz Referenten: Prof. Dr. Marc H. Scholl Prof. Dr. Marcel Waldvogel Tag der mündlichen Prüfung: 17. Juli 2012 Abstract XML and state-of-the-art XML database management systems (XML-DBMSs) can play a leading role in far more application domains as it is currently the case. Even in their basic configuration, they entail all components necessary to act as central systems for complex search and retrieval tasks. They provide language-specific index- ing of full-text documents and can store structured, semi-structured and binary data. Besides, they offer a great variety of standardized languages (XQuery, XSLT, XQuery Full Text, etc.) to develop applications inside a pure XML technology stack. Benefits are obvious: Data, logic, and presentation tiers can operate on a single data model, and no conversions have to be applied when switching in between. This thesis deals with the design and development of XML/XQuery driven informa- tion architectures that process formerly heterogeneous data sources in a standardized and uniform manner. Filesystems and their vast amounts of different file types are a prime example for such a heterogeneous dataspace. A new XML dialect, the Filesystem Markup Language (FSML), is introduced to construct a database view of the filesystem and its contents. FSML provides a uniform view on the filesystem’s contents and allows developers to leverage the complete XML technology stack on filesystem data.

  • Benchmarking Virtuoso 8 at the Mighty Storage Challenge 2018: Challenge Results
    Benchmarking Virtuoso 8 at the Mighty Storage Challenge 2018: Challenge Results Milos Jovanovik1;2 and Mirko Spasi´c1;3 1 OpenLink Software, United Kingdom 2 Faculty of Computer Science and Engineering, Ss. Cyril and Methodius University in Skopje, Macedonia 3 Faculty of Mathematics, University of Belgrade, Serbia {mjovanovik,mspasic}@openlinksw.com Abstract. Following the success of Virtuoso at last year's Mighty Stor- age Challenge - MOCHA 2017, we decided to participate once again and test the latest Virtuoso version against the new tasks which comprise the MOCHA 2018 challenge. The aim of the challenge is to test the performance of solutions for SPARQL processing in aspects relevant for modern applications: ingesting data, answering queries on large datasets and serving as backend for applications driven by Linked Data. The chal- lenge tests the systems against data derived from real applications and with realistic loads, with an emphasis on dealing with changing data in the form of streams or updates. Virtuoso, by OpenLink Software, is a modern enterprise-grade solution for data access, integration, and rela- tional database management, which provides a scalable RDF Quad Store. In this paper, we present the final challenge results from MOCHA 2018 for Virtuoso v8.0, compared to the other participating systems. Based on these results, Virtuoso v8.0 was declared as the overall winner of MOCHA 2018. Keywords: Virtuoso, Mighty Storage Challenge, MOCHA, Benchmarks, Data Storage, Linked Data, RDF, SPARQL 1 Introduction Last year's Mighty Storage Challenge, MOCHA 2017, was quite successful for our team and Virtuoso { we won the overall challenge [6, 11].

  • Three Decades of Data Integration — All Problems Solved?
    THREE DECADES OF DATA INTEGRATION — ALL PROBLEMS SOLVED? Patrick Ziegler and Klaus R. Dittrich Database Technology Research Group, Department of Informatics, University of Zurich Winterthurerstrasse 190, CH-8057 Zürich, Switzerland {pziegler|dittrich}@ifi.unizh.ch Abstract Data integration is one of the older research fields in the database area and has emerged shortly after database systems were first introduced into the business world. In this paper, we briefly introduce the problem of integration and, based on an architectural perspective, give an overview of approaches to address the integration issue. We discuss the evolution from structural to semantic integra- tion and provide a short outlook on our own research in the SIRUP (Semantic Integration Reflecting User-specific semantic Perspectives) approach. Keywords: Data integration, integration approaches, semantic integration 1. Introduction In today’s business world, it is typical that enterprises run different but co- existing information systems. Employing these systems, enterprises struggle to realize business opportunities in highly competitive markets. In this setting, the integration of existing information systems is becoming more and more in- dispensable in order to dynamically meet business and customer needs while leveraging long-term investments in existing IT infrastructure. In general, integration of multiple information systems aims at combining selected systems so that they form a unified new whole and give users the illu- sion of interacting with one single information system. The reason for integra- tion is twofold: First, given a set of existing information systems, an integrated view can be created to facilitate information access and reuse through a single information access point. Second, given a certain information need, data from different complementing information systems is to be combined to gain a more comprehensive basis to satisfy the need.

  • Data Access with ADO.NET by Andrew Troelsen
    APPENDIX Data Access with ADO.NET by Andrew Troelsen This is Chapter 13 of C#and the .NET Platform (Apress, 2001). From this point on, all references to other chapters and appendixes are to those from Troelsen and not to chapters and appendixes within Distributed .NET Programming in C#. Unless you are a video game developer by trade, you are probably interested in data­ base manipulation. As you would expect, the .NET platform defines a number of types (in a handful of related namespaces) that allow you to interact with local and remote data stores. Collectively speaking, these namespaces are known as ADO.NET, which as you will see is a major overhaul of the classic ADO object model. This chapter begins by examining some core types defined in the System.Data namespace-specifically DataColumn, DataRow, and DataTable. These classes allow you to define and manipulate a local in-memory table of data. Next, you spend a good deal of time learning about the centerpiece of ADO.NET, the DataSet. As you will see, the DataSet is an in-memory representa­ tion of a collection of interrelated tables. During this discussion, you will learn how to programmatically model table relationships, create custom views from a given table, and submit queries against your in-memory DataSet. After discussing how to manipulate a DataSet in memory, the remainder of this chapter illustrates how to obtain a populated DataSet from a Database Man­ agement System (DBMS) such as MS SQL Server, Oracle, or MS Access. This entails an examination of .NET "managed providers" and the OleDbDataAdapter and SqlDataAdapter types.
