This poster presents a hash key for bibliographic records called bibkey. It is shown how bibkey can be used to detect duplicates and to map similar bibliographic records among distributed databases.

Replication is a key factor for improving the availability and reliability of data in a distributed database system. A Major restriction is that replicated copies should behave like a single copy. Many replica control algorithms have been proposed for solving the problem, but the performance of various replica control algorithms has received relatively little attention. In this paper, the perfo...

In this paper we consider processing entity join queries in a wide area multidatabase environmen t where the query processing cost is dominated by the cost of data transmission An entity join oper ation integrates tuples representing the same en tities from di erent relations in which inconsistent data may exist The semijoin technique has been successfully used in a distributed database system ...

In this paper we describe a services oriented software system to provide basic database support for efficient execution of applications that make use of scientific datasets in the Grid. This system supports two core operations: efficient selection of the data of interest from distributed databases and efficient transfer of data from storage nodes to compute nodes for processing. We present its ...

KMDB has been constructed on a database software MutationView [1] which was designed to compile various mutation data as a distributed database and to provide graphical presentation of data analysis. To date, we constructed five separate KMDBs for eye, heart, ear, brain and cancer in which a total of 1593 entries of mutations are found for 38 different genes which are involved in 35 distinct di...

In this paper, our research objective is to develop a database virtualizat ion technique in order to let data analysts or other users who apply data mining methods to their jobs use all ubiquitous databases on the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet databases and data cleansing works. In th...

Intelligent products carrying their own information are more and more present nowadays. In recent years, some authors argued the usage of such products for the Supply Chain Management Industry. Indeed, a multitude of informational vectors take place in such environments like fixed databases or manufactured products on which we are able to embed significant proportion of data. By considering dis...

One of the primary goals of the project has been to develop (and implement with real databases) a search and retrieval system based on international standards that is capable of searching cross-domain resources held in multiple locations. This goal has been achieved, although even more resources and services have yet to be added to the system, and truly seamless integration of these services wi...

Over the past several years, the National Institute of Statistical Sciences (NISS) has developed methodology to perform statistical analyses that, in effect, integrate data in multiple, distributed databases, but without literally bringing the data together in one place. In this paper, we summarize that research, but focus on issues that are not understood. These include inability to perform ex...
