Title: | Graph-driven Federated Data Management | Authors: | Nadal, Sergi Abello, Alberto Romero, Oscar VANSUMMEREN, Stijn Vassiliadis, Panos |
Issue Date: | 2021 | Publisher: | IEEE | Source: | IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING, | Status: | Early view | Abstract: | Modern data analysis applications require the ability to provide on-demand integration of data sources while offering a flexible and user-friendly query interface. Traditional techniques for answering queries using views, focused on a rather static setting, fail to address such requirements. To overcome these issues, we propose a fully-fledged data integration approach based on graph-based constructs. The extensibility of graphs allows us to extend the traditional framework for data integration with view definitions. Furthermore, we also propose a query language based on subgraphs. We tackle query answering via a query rewriting algorithm based on well-known algorithms for answering queries using views. We experimentally show that the proposed method yields good performance and does not introduce a significant overhead. | Keywords: | Data integration;data wrangling;GLAV mappings | Document URI: | http://hdl.handle.net/1942/34260 | ISSN: | 1041-4347 | e-ISSN: | 1558-2191 | DOI: | 10.1109/TKDE.2021.3077044 | Category: | A1 | Type: | Journal Contribution |
