NoSQL Data Models

Overview of this book

Big Data environments are now to be handled in most current applications, this book addresses the latest issues and hurdles that are encountered in such environments. The book begins by presenting an overview of NoSQL languages and systems. Then, you’ll evaluate SPARQL queries over large RDF datasets and devise a solution that will use the MapReduce framework to process SPARQL graph patterns. Next, you’ll handle the production of web data, generate a set of links between two different datasets and overcome different heterogeneity problems. Moving ahead, you’ll take the multi-graph based approach to overcome challenges faced by the RDF data management community. Finally, you’ll deal with the flexible querying of graph databases and textual data management. By the end of this book, you’ll have gathered essential information on big data challenges faced by NoSQL databases.

The chapter introduces the main concepts of interest in the context of data linking. We start by an overview of the Semantic Web.

3.1.1. The Semantic Web vision

With the advent of the World Wide Web (WWW), accessing information has become quicker and simpler via Web documents which are part of a “global search space”. In this version of the Web, knowledge is accessible by traversing hypertext links using Web browsers. In recent years, this global information space of connected documents is currently evolving into a global Web of data – the Semantic Web – where both data and documents are linked. Tim Berners-Lee, the inventor of the WWW, defined the Semantic Web as “not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation” [BER 01].

The transition of the current document-oriented Web to a Web of interlinked data has...
