Abstract The Tracked Vehicle Workstation (TVWS) is a distributed, object-oriented design environment that stores the large amounts of data associated with mechanical system’s design and analysis across heterogeneous UNIX† machines on a network. A Distributed ASCII File Storage (DAFS) server was developed to provide an easy to port, easy to modify means of retrieving and updating files on remote machines. This paper describes the different techniques and difficulties of methods the TVWS environment has used previously, including commercial solutions, single-node storage and the Network File System (NFS)‡, as well as a description of the current method utilizing DAFS.

Open Grid Services Architecture

OGSA-DAI (Open Grid Services Architecture Data Access and Integration) is a framework for building distributed data access and integration systems. Until recently, it lacked the built-in functionality that would allow easy creation of federations of distributed data sources. The latest release of the OGSA-DAI framework introduced the OGSA-DAI DQP (Distributed Query Processing) resource. The new resource encapsulates a distributed query processor, that is able to orchestrate distributed data sources when answering declarative user queries. The query processor has many extensibility points, making it easy to customize. We have also introduced a new OGSA-DAI V iews resource that provides a flexible method for defining views over relational data. The interoperability of the two new resources, together with the flexibility of the OGSA-DAI framework, allows the building of highly customized data integration solutions.

Abstract Semantic data integration from heterogeneous, distributed data silos enables Digital Humanities research and application development employing a larger, mutually enriched and interlinked knowledge graph. However, data integration is challenging, involving aligning the data models and reconciling the concepts and named entities, such as persons and places. This paper presents a record linkage process to reconcile person references in different military historical person registers with structured metadata. The information about persons is aggregated into a single knowledge graph. The process was applied to reconcile three person registers of the popular semantic portal “WarSampo – Finnish World War 2 on the Semantic Web”. The registers contain detailed information about some 100 000 people and are individually maintained by domain experts. Thus, the integration process needs to be automatic and adaptable to changes in the registers. An evaluation of the record linkage results is promising and provides some insight into military person register reconciliation in general.

Today, data with hidden knowledge drives almost every activity in business and enterprises, etc. Computer technology has been successfully solved the problems with data storage, query, usability and transmission. But how to integrate all these huge distributed and heterogeneous data together for high level applications is still a critical problem. With research on the software bus and multi-agents technologies, it illustrates multi-agents based design architecture for data integration

In this paper, on the basis of the data warehouse integration mechanisms, use Object-oriented analysis methods, take the ITIS’s functions and data needs as the starting point, promote and optimize the ETL method and form a Tourism-oriented ITIS data integration model. The “wisdom tourism” is explained elaborately. Then it shows what data integration is and how to use integration.
