Query processing in distributed ORION

2005
In this paper we describe query processing strategies we have developed and implemented in the distributed version of the ORION object-oriented database system. The ORION query model is based on the ORION object-oriented data model. Further, we have adopted the response time as the primary objective function for query optimization. The query-processing

TwigMRR: Distributed XML Twig Query Processing

2014 13th International Symposium on Distributed Computing and Applications to Business, Engineering and Science, 2014
Twig query is considered the core query pattern in most XML query language. With the XML document size becoming larger, single site cannot deal with such volume data in storage capacity and compute ability. Partitioning the large data and distributed parallel processing query is an efficient and effective way. This paper proposes Twig MRR algorithm for

Efficient processing of distributed set queries

Proceedings. PARBASE-90: International Conference on Databases, Parallel Architectures, and Their Applications, 2002
The problem of efficiently processing queries that manipulate sets is considered with the objective of minimizing the processing cost by reducing the size of transmitted data as much as possible. The semantics of set operations is used to achieve this goal. A set query has the general form SET 1 op SET 2.

Querying and monitoring distributed business processes

Proceedings of the VLDB Endowment, 2008
A 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,

Using constraints for distributed query processing

Proceedings Nineteenth Annual International Computer Software and Applications Conference (COMPSAC'95), 2002
Constraints 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.

A Cooperative Distributed Query-Processing Approach

2009
Although Distributed Database Management Systems (DDBMS) have been studied for many years there has been little or no emphasis that these studies have put on dynamic systems where database systems can join and depart a group of co-operating DBMS systems.

Spatial Query Processing on Distributed Databases

2013
In recent years, with the ubiquity of location-aware mobile devices and widespread deployment of wireless networks, location-based services (LBSs) have become popular rapidly. Spatial queries, one useful LBS, enable users to query about the interested data objects near them.
