Interoperable Query Processing among Heterogeneous Databases

by Yahui Chang - University of Maryland , 1994
"... The proliferation of database systems based on different data models and query languages has created the need for techniques that support interoperability so that information may be shared among the database systems. This dissertation proposal describes a technique to support interoperable query pro ..."

On the Use of Description Logic for Semantic Interoperability of Enterprise Systems

by Esma Yahia, Jing Yang, Alexis Aubry, Hervé Panetto - in Proceedings of 4 th International workshops on Enterprise, Interoperability and Networking (EI2N OTM Confederated International Workshops and Posters, Villamoura, Portugal, LNCS 5872 , 2009
"... Abstract. With the growing advances in computing and communications technologies, the concept of system-of-systems (SoS) becomes widely recognized as it offers potential benefits and new challenges. Relevant perspectives related to SoS constitutes nowadays an active domain of research, among them th ..."

to evaluate and formalize it in order to identify semantic gaps between information systems concepts and models. It provides, through an example, an approach to use Description Logic for evaluating semantic interoperability concerns.

Metamodelling of Domain-Specific Standards for Semantic Interoperability

by Wilhelm Hasselbring , Susanne Pedersen , 2005
"... Abstract. The IEEE defines interoperability as the ability of two or more systems or components to exchange information and to use the information that has been exchanged. Semantic interoperability problems arise in various business domains Metamodelling Metamodels are models of models, e.g., a UM ..."

Interoperability in Costal Zone Monitoring Systems: Resolving Semantic Heterogeneities

by Through Ontology Driven, R. L. King, S. Durbha, N. H. Younan
"... Ontologies are widely recommended as a means of rectifying semantic heterogeneity. The advantage of using ontologies is that they can provide a conceptual schema regardless of a data set's format, structure, or size MSU is developing an ontological framework for resolving semantic heterogeneity ..."

Privacy-preserving semantic interoperation and access control of heterogeneous databases

by Prasenjit Mitra, Chi-chun Pan, Peng Liu, et al. - IN: PROC. ACM CONF. ON COMPUTER AND COMMUNICATIONS SECURITY , 2006
"... Today, many applications require users from one organization to access data belonging to organizations. While traditional solutions offered for the federated and mediated databases facilitate this by sharing metadata, this may not be acceptable for certain organizations due to privacy concerns. In t ..."
Abstract - Cited by 12 (0 self) - Add to MetaCart
. In this paper, we propose a novel solution – Privacy-preserving Access Control Toolkit (PACT) – that enables privacy-preserving secure semantic access control and allows sharing of data among heterogeneous databases without having to share metadata. PACT uses encrypted ontologies, encrypted ontology

NCL: A Common Language for Achieving Rule-Based Interoperability among Heterogeneous Systems

by Stanley Y. W. Su, Herman Lam, Tsae-feng Yu, Javier A. Arroyo-Figueroa, Zhidong Yang, Sooha Lee - JOURNAL OF INTELLIGENT INFORMATION SYSTEMS, SPECIAL ISSUE ON INTELLIGENT INTEGRATION OF INFORMATION , 1996
"... For achieving interoperability among heterogeneous computing systems, the Object Management Group (OMG) has adapted the Common Object Request Broker Architecture (CORBA) and the use of an Interface Definition Language (IDL) for specifying object properties and operations which encapsulate the data a ..."

Query optimization in heterogeneous DBMS

by Weimin Du, Ravi Krishnamurthy, Ming-chien Shan - In Proc. of VLDB, pp 277--91 , 1992
"... We propose a query optimization strategy for heterogeneous DBMSs that extends the traditional optimizer strategy widely used in commercial DBMSs to allow execution of queries over both known (i.e., proprietary) DBMSs and foreign vendor DBMSs that conform to some standard such as providing the usual ..."

management systems (DBMSs) h ave gained its due recognition as a result of the advent of open systems. Typically this heterogeneity may result from semantic discrepancies in the data, multiple data models, different systems, etc. All of these are consequences of the need for independent database systems

Load balancing in structured p2p systems

by Ananth Rao, Karthik Lakshminarayanan, Sonesh Surana, Richard Karp, Ion Stoica , 2003
"... Most P2P systems that provide a DHT abstraction distribute objects among “peer nodes ” by choosing random identifiers for the objects. This could result in an O(log N) imbalance. Besides, P2P systems can be highly heterogeneous, i.e. they may consist of peers that range from old desktops behind mode ..."

Semantic Interoperability Context, Issues, and Research Directions

by Paul Johannesson, M. Hasan Jamil - Proc. of the Second International Conference on Cooperative Information Systems, 180 - 191 , 1994
"... An increasing dependence and cooperation between organisations has created a need for many enterprises to access remote as well as local information sources. Thus, it becomes important to be able to interconnect existing, heterogeneous information systems. One form of heterogeneity is semantic heter ..."

heterogeneity, which occurs when there is a disagreement regarding the interpretation and intended use of related information, or when the same phenomenon in a Universe of Discourse is modelled in different ways in two systems. In this paper, we survey the basic problems caused by semantic heterogeneity
