Mobile join operators for restricted sources

Özakar, Belgin; Morvan, Franck; Hameurlain, Abdelkader (Hindawi Publishing, 2005)

We consider the problem of query execution when there is limited access to the relations, i.e. when binding patterns require values to be specified in order to get data from the relation. This problem is common in virtual ...
Resource allocation algorithm for a relational join operator in grid systems

Çokuslu, Deniz; Hameurlain, Abdelkader; Erciyeş, Kayhan; Morvan, Franck (Association for Computing Machinery, 2012)

Grid systems become very popular during the last decade because of their rapidly increasing computational capabilities. On the other hand, the advances on different domains cause enormous increase in the scale of the ...
Robust placement of mobile relational operators for large scale distributed query optimization

Ergenç, Belgin; Morvan, Franck; Hameurlain, Abdelkader (IEEE, 2007)

This paper presents a compile-time placement method of mobile relational operators MROs in a large scale environment. MROs are self adaptive to changing runtime conditions by deciding their execution place if they discover ...
