Query Processing and Optimization on the Web

Mourad Ouzzani, Athman Bouguettaya
2004 Distributed and parallel databases  
Those characteristics impede a straightforward application of classical query optimization techniques.  ...  A major challenge relates to query optimization. Indeed, querying multiple information sources scattered on the Web raises several barriers for achieving efficiency.  ...  The authors would like to thank the anonymous reviewers and Brahim Medjahed for their valuable comments on earlier drafts of this paper.  ...

A Database-Centric Framework for the Modeling, Simulation, and Control of Cyber-Physical Systems in the Factory of the Future

Andrea Bonci, Massimiliano Pirani, Sauro Longhi
2017 Journal of Intelligent Systems  
The full expression of the potentialities in the presented approach is expected in particular for applications where tiny and distributed embedded devices collaborate to a shared computing task of relevant  ...  The role of database management systems is becoming central for control and automation technology in this new industrial scenario.  ...  With the use of active and distributed embedded database, we propose a framework that dynamically allows the components, as plug-ins, to participate in the system.  ...

Skeena: Efficient and Consistent Cross-Engine Transactions [article]

Jianqiu Zhang, Kaisong Huang, Tianzheng Wang, King Lv
2021 arXiv   pre-print
With the growing DRAM capacity and core count in modern servers, database systems are becoming increasingly multi-engine to feature a heterogeneous set of engines.  ...  In particular, a memory-optimized engine and a conventional storage-centric engine may coexist for various application needs.  ...  DESIGN PRINCIPLES We distill a set of desired properties and design principles that a cross-engine mechanism like Skeena should follow: • Low Overhead.  ...
