چکیده

Traditional modeling techniques typically focus on the static part of databases and ignore their dynamic part (e.g., queries or data-centric workflows). In this paper, we first introduce and sketch a graph-based model that captures relations, views, constraints and queries. We then present HECATAEUS, a tool for implementing and visualizing the above framework.

An effective and versatile keyword search engine on heterogenous data sources

We present EASE, an effective and versatile keyword search engine that enables users to easily access the heterogenous data composed of unstructured, semi-structured and structured data, without the need of learning XPath/XQuery or SQL languages. EASE addresses a challenge in keyword search that has been neglected in the literature: how to efficiently and adaptively process keyword queries on t...

A Pure Graph-Based Solution to the SCG-1 Initiative

This paper answers the SCG-1 initiative. The room allocation problem provided has been solved in a generic and automatic way. The solution is based on a totally declarative formal model. Basic constructs are simple graphs and the fundamental operation for doing reasonings is the graph morphism known as projection. The other formal constructs are rules and constraints defined in terms of simple ...

Analyzing SQL Query Logs using Multi-Relational Graphs

Computer Science 6 (Data Management), FAU Erlangen-Nürnberg {andreas.wahl|richard.lenz}@fau.de Analytical SQL queries are a valuable source of information. They contain expert knowledge that cannot be inferred from schemas or content alone. Consider, for example, data lake scenarios, where relational and semi-structured data sources are combined in a single storage and processing environment. D...

Evaluation of SPARQL Property Paths via Recursive SQL

Property paths, a part of the proposed SPARQL 1.1 standard, allow for non-trivial navigation in RDF graphs. We investigate the evaluation of SPARQL queries with property paths in a relational RDF store. We propose a translation of SPARQL property paths into recursive SQL and discuss possible optimization strategies.

Capturing and Querying Multiple Aspects of Semistructured Data

Motivated to a large extent by the substantial and growing prominence of the World-Wide Web and the potential benefits that may be obtained by applying database concepts and techniques to web data management, new data models and query languages have emerged that contend with the semistructured nature of web data. These models organize data in graphs. The nodes in a graph denote objects or value...
