On heterogeneous distributed geoscientific query processing
Proceedings RIDE '96. Sixth International Workshop on Research Issues in Data Engineering, 2002Geoscience studies produce data from various observations, experiments, and simulations at an enormous rate. With proliferation of geographic applications, scientific data formats, and storage systems, interoperability remains an important geoscientific data management issue that is often overlooked in current geoscientific query processing research ...

Querying and monitoring distributed business processes
Proceedings of the VLDB Endowment, 2008A business process (BP for short) consists of a group of business activities undertaken by one or more organizations in pursuit of some particular goal. It usually operates in a cross-organization, distributed environment and the software implementing it is fairly complex. Standards facilitate the design, deployment,

Distributed query processing and data sharing
2017 12th International Conference for Internet Technology and Secured Transactions (ICITST), 2017Data privacy is becoming an increasing concern in industries where huge data repositories are dealt with. Most of them need to share private data across distinct organizations. In this paper, we propose a modification to an existing framework wherein data sharing across distributed databases is handled without compromising the sensitive nature of ...

QoS-based Distributed Query Processing
Ingénierie des systèmes d'information, 2004Among the essential functionalities supported by distributed multimedia systems, quality of service (QoS) is of prime interest and requires the involvement of different system components. This unction aims to control and guarantee the level of quality that the system is able to offer to the user. The QoS requirements may concern system performance, the

A localized approach to distributed query processing
1990To process queries against a global schema in a distributed multidatabase system, query transformation which maps the query against the global schema to the local schemas is necessary. In this paper, a localized approach is presented which optimizes distributed query processing. This approach transforms a query to subqueries.

A Method for Processing Distributed Database Queries
IEEE Transactions on Software Engineering, 1984The efficient processing of distributed database queries is of great importance in a distributed database management system. The algorithm-S described in this research is very efficient and low in complexity. The algorithm assumes uniformly distributed data within the attributes of a relation and data independence across attributes.

Using constraints for distributed query processing
Proceedings Nineteenth Annual International Computer Software and Applications Conference (COMPSAC'95), 2002Constraints are combined with join operations to minimize the amount of data transmission required for distributed query processing. We identify and exploit two important concepts: reducers and abstractors. A constraint can serve as a reducer if it is a sufficient and/or necessary condition for a query.
