The loose and dynamic association between peers in a peer to peer integration has meant that to date implementations of peer to peer systems have been based on the exchange of les identi ed with a very limited set of attributes and no schema is used to describe the data within those les This paper extends an existing approach to data integration called both as view to be an e cient mechanism fo...

Schema matching is considered as one of the essential phases of data integration in database systems. The main aim of the schema matching process is to identify the correlation between schema which helps later in the data integration process. The main issue concern of schema matching is how to support the merging decision by providing the correspondence between attributes through syntactic and ...

We discuss the different types of schema architectures which could be supported by distributed database systems, making a clear distinction between logical, physical, and federated distribution. We elaborate on the additional mapping information required in architecture based on logical distribution in order to support retrieval as well as update operations. We illustrate the problems in schema...

The paper explains the necessity, for humanoid robots, of the body schema, as a middleware between motor cognition and motor control. A speci ̄c model of body schema is described, based on the Passive Motion Paradigm, which uses force ̄elds for representing goals and internal/ external constraints. The integration of the body schema with motor control is discussed in relation with whole body move...

There are many external resources and heterogeneous data on the internet that an organization or user may need to improve the decision making process. It is therefore, very important and critical that this information are complete, precise and can be acquired on time. Most web sources provide data in semi-structured form on the internet. The combination of semi-structured data from different so...

Research in the area of data integration has resulted in approaches such as federated and multidatabases, mediation, data warehousing, global information systems, and the model management/schema matching approach. Architecturally, approaches can be categorized into those that integrate against a single global schema and those that do not, while on the level of inter-schema constraints, most wor...

The loose and dynamic association between peers in a peerto-peer integration has meant that, to date, implementations of peer-topeer systems have been based on the exchange of files identified with a very limited set of attributes, and no schema is used to describe the data within those files. This paper extends an existing approach to data integration, called both-as-view, to be an efficient m...

To create new added value the Semantic Web has to provide new means for business integration enabling open world-wide cooperation between various enterprises. Existing business integration techniques assume the enterprises having similar conceptual models of the objects being exchanged, and this limits their application areas. The Semantic Web needs to possess a technique capable of mapping dif...

-With the arrival of knowledge service age, the integration of information resources of Legacy System will turn from system level to standard level. Metadata schema registry will be the research hotspot of library science and intelligence science, and it can solve the heterogeneous problem between information systems. This paper is faced to the requirements which knowledge service have of integ...
