Multidatabase language requirements

Abstract

The integration transparency of a multidatabase system depends heavily on the diversity of local language interfaces and models. These parameters are not predetermined but application dependent. The flexibility of a new concept called megaprogramming can help to solve the multidatabase problem. The author evaluates this idea based on logic programming and discusses how such a language can serve simultaneously as global query language, for transaction specification and execution, and for the representation of static integration information.<>
