Data integration with dependent sources

Anish Das Sarma, Xin Luna Dong, Alon Halevy
2011 Proceedings of the 14th International Conference on Extending Database Technology - EDBT/ICDT '11  
Data integration systems offer users a uniform interface to a set of data sources.  ...  of dependent sources, where some sources copy parts of their data from others.  ...  System We are building a system called IDS (Integrating Dependent Sources), for integrating a large number of data sources, where dependencies may exist between sources.  ...

Using Graph Neural Networks for Program Termination [article]

Yoav Alon, Cristina David
2022 arXiv   pre-print
We also illustrated how the information provided by semantic segmentation can be combined with program slicing to further aid debugging.  ...  Intuitively, it enhances some parts of the input data while diminishing others with the expectation that the network is focusing on a small, but important part of the data.  ...  Instead of looking at execution traces like the aforementioned works, we are interested in using the source code with the assumption that it contains patterns that can assist in understanding its functionality  ...

Integration of Web Sources Under Uncertainty and Dependencies Using Probabilistic XML [chapter]

M. Lamine Ba, Sebastien Montenez, Ruiming Tang, Talel Abdessalem
2014 Lecture Notes in Computer Science  
We study in this vision paper the problem of integrating several web data sources under uncertainty and dependencies.  ...  We present a concrete application with web sources about objects in the maritime domain where uncertainties and dependencies are omnipresent.  ...  Main challenges We base the design of our intended data integration model for uncertain web data sources with dependencies on three main requirements. 1.  ...

Reflections on Data Integration for SDN

Anduo Wang, Jason Croft, Eduard Dragut
2017 Proceedings of the ACM International Workshop on Security in Software Defined Networks & Network Function Virtualization - SDN-NFVSec '17  
The control applications act as data sources generating network state, and the dataplane becomes the integrated whole.  ...  Based on this model, we explore extensions to data integration systems called behavioral dependency, a formal notion that captures the dynamic interactions between the control applications.  ...  More formally, a data integration system is defined as I = G, S, M , with a global schema G, semantic mappings M, and data sources S.  ...

Data Integration - Challenges, Techniques and Future Directions: A Comprehensive Study

Bazeer Ahamed, T. Ramkumar
2016 Indian Journal of Science and Technology  
Optimizing the queries depending on the data source is also another major requirement to provide efficient and faster results reducing the data retrieval latencies.  ...  Data integration techniques mainly focusing on integration of data in several levels and applying independent or unified query over the data available.  ...  Integrating Data: The Methods In this study, data integration is divided into three categories, depending on the level when the integration is performed and depending on the data source where the query  ...

A Statistical Data Fusion Technique in Virtual Data Integration Environment

Mohamed M. Hafez, Ali H. El Bastawissy, Osman H. Mohamed
2013 International Journal of Data Mining & Knowledge Management Process  
Data fusion in the virtual data integration environment starts after detecting and clustering duplicated records from the different integrated data sources.  ...  In this paper, a statistical technique for data fusion is introduced based on some probabilistic scores from both data sources and clustered duplicates.  ...  So, as a preprocessing step for all data sources in the data integration environment, the dependency between all attributes in each table in data source is calculated and tored in the Dependency Statistics  ...

Modeling the Data Warehouse Refreshment Process as a Workflow Application

Mokrane Bouzeghoub, Françoise Fabret, Maja Matulovic-Broqué
1999 Design and Management of Data Warehouses  
We conceptually define the refreshment process as a workflow whose activities depend on the available products for data extraction, cleaning and integration, and whose coordination events depend on the  ...  application domain and on the required quality in terms of data freshness.  ...  Similarly data reconciliation (also called multi-source cleaning) can be separated from or merged with data integration (multi-sources operations).  ...

IBIS: Semantic Data Integration at Work [chapter]

Andrea Calì, Diego Calvanese, Giuseppe De Giacomo, Maurizio Lenzerini, Paolo Naggar, Fabio Vernacotola
2003 Lecture Notes in Computer Science  
IBIS adapts and integrates the data extracted from the sources making use of the constraints in the global schema, so as to answer queries at best with the information available.  ...  IBIS deals with limitations in accessing data sources, and exploits techniques developed for querying sources with access limitations in order to retrieve the maximum set of answers.  ...  In order to assign semantics to a data integration application I = G, S, M , we start with the data at the sources, and specify which data satisfy the global schema.  ...

On the Expressive Power of Data Integration Systems [chapter]

Andrea Calì, Diego Calvanese, Giuseppe De Giacomo, Maurizio Lenzerini
2002 Lecture Notes in Computer Science  
There are basically two approaches for designing a data integration system.  ...  We introduce the notion of query-preserving transformation, and query-reducibility between data integration systems, and we show that, when no integrity constraints are allowed in global schema, the LAV  ...  Introduction Data integration is the problem of combining the data residing at different sources, and providing the user with a unified view of these data, called global (or, mediated) schema [9] .  ...

A UML Profile for Modeling Schema Mappings [chapter]

Stefan Kurz, Michael Guppenberger, Burkhard Freitag
2006 Lecture Notes in Computer Science  
An important step within this process is the formulation of an integration mapping which specifies how to select, integrate and transform the data stored in the heterogeneous local information sources  ...  This integration mapping can then be used to perform the data integration itself. In this paper, we present a UML-based approach to define integration mappings.  ...  whenever information systems have to deal with several legacy data sources.  ...

The work "Data Integration under Integrity Constraints", published at the CAiSE 2002 Conference, proposes a rewriting technique for answering queries in data integration systems, when the global schema  ...  contains the classical key and foreign key constraints, and the mapping between the data sources and the global schema is of the global-as-view type.  ...  Acknowledgements We acknowledge the support of the EU through the large-scale integrating project (IP) Optique (Scalable End-user Access to Big Data), grant agreement n. FP7-318338.  ...

2016 Zenodo  
With regard to the scalability of data fusion, it has been shown that DF with source dependency runs in polynomial time [7] .  ...  Source Dependency In the sections above we assumed that all sources are independent. This is not always the case when we deal with real-world data.  ...
