On building a hyperdistributed database

摘要

Sharing data among disparate databases has so far mostly been achieved through some form of ad-hoc schema integration. This approach becomes less tractable as the number of participating database increases. Therefore, the complexity of making autonomous heterogeneous databases interoperate is dependent on adequately addressing the autonomy and heterogeneity issues. In this paper, we describe a prototype that implements an approach which addresses these issues in the context of large multidatabase systems. In particular, we describe a scheme that builds a Hyperdistributed Database using a two-staged approach. We also describe how conglomerations of databases are formed, modified, and evolved.
