A taxonomy and current issues in multidatabase systems
A taxonomy of global information-sharing systems is presented, and the way in which multidatabase systems fit into the spectrum of solutions is discussed. The taxonomy is used as a basis for defining
Scheduling and Load Balancing in Parallel and Distributed Systems
This book discusses how to schedule the processes among processing elements to achieve the expected performance goals, such as minimizing execution time, minimizing communication delays, or maximizing resource utilization.
Automated resolution of semantic heterogeneity in multidatabases
The Summary Schemas Model (SSM) is proposed as an extension to multidatabase systems to aid in semantic identification and a simulation of the SSM is presented to compare imprecise-query processing with corresponding query-processing costs in a standard multid atabase system.
TF-ICF: A New Term Weighting Scheme for Clustering Dynamic Data Streams
The results show that TF-ICF can produce document clusters that are of comparable quality as those generated by the widely recognized term weighting schemes and it is significantly faster than those methods.
Data Organization and Retrieval on Parallel Air Channels: Performance and Energy Issues
Simulation results indicate that the employment of indexing scheme and proper scheduling of object retrieval along the parallel channels drastically reduces both the access latency and power consumption at the mobile unit.
Data Broadcasting in a Mobile Environment
This chapter investigates solutions proposed for major research issues including indexing scheme, broadcasting over single and parallel channels, data distribution and replication strategy, conflict resolution, and data retrieval method, and high performance and low power consumption.
Object-oriented multidatabase systems
Dataflow architectures and multithreading
Multithreading offers a viable alternative for building hybrid architectures that exploit parallelism and more research is still needed to develop compilers for conventional languages that can produce parallel code comparable to that of parallel functional languages.
Effective clustering of complex objects in object-oriented databases
This paper investigates the updating effects of clustering and suggests a dynamic reclustering scheme to reorganize related objects on the disk and shows that the leveled clustering scheme has a better access time compared with a single-level clustering schemes.
