Query Translation in a Database Sharing Peer to Peer Network

In a peer to peer database sharing network users query data from all peers using one query as if they are querying data from one database. Implementing such a facility requires solutions to the problems of schema conflicts and query translation. Query translation is the problem of rewriting a query posed in terms of one schema to the query in terms of the other schema. Schema conflicts refer to the problems which come as the results of integrating data from databases which were designed independently. This paper proposes the architecture for integrating and querying databases in the peer to peer (P2P)network

A New Design for Open and Scalable Collaboration of Independent Databases in Digitally Connected Enterprises

“Digitally connected enterprises” refers to e-business, global supply chains, and other new business designs of the Knowledge Economy; all of which require open and scalable information supply chains across independent enterprises. Connecting proprietarily designed and controlled enterprise databases in these information supply chains is a critical success factor for them. Previous connection designs tend to rely on “hard-coded” regimes, which do not respond well to disruptions (including changes and failures), and do not afford these enterprises sufficient flexibility to join simultaneously in multiple supply chain regimes and share information for the benefit of all. The paper develops a new design: It combines matchmaking with global database query, and thereby supports the interoperation of independent databases to form on-demand information supply chains. The design provides flexible (re-)configuration to decrease the impact of disruption, and proactive control to increase collaboration and information sharing. More broadly, the papers results contribute to a new Information System design method for massively extended enterprises, and facilitate new business designs using digital connections at the level of databases

The Model-Assisted Global Query System for Multiple Databases in Distributed Enterprises

Today's enterprises typically employ multiple information systems, which are independently developed, locally administered, and different in logical or physical designs. Therefore, a fundamental challenge in enterprise information management is the sharing of information for enterprise users across organizational boundaries; which requires a global query system capable of providing on-line intelligent assistance to users. Conventional technologies, such as schema-based query languages and hard-coded schema integration are not sufficient to solve this problem. This research develops a new approach, "model-assisted global query system, " that utilizes an on-line repository of enterprise metadata- the metadatabase- to facilitate global query formulation and processing with certain desirable properties such as adaptiveness and open systems architecture. A definitional model characterizing the various classes and roles of the minimally required metadata as knowledge for the system i
