In order to make database systems interoperate with systems beyond
traditional application areas a new paradigm called ``exporting database
functionality'' as a radical departure from traditional thinking has been
proposed in research and development. Traditionally, all data is loaded
into and owned by the database, whereas according to the new paradigm
data may reside outside the database in external repositories or
archives. Nevertheless, database functionality, such as query processing,
and indexing, is provided exploiting interoperability of the DBMS with the
external repositories. Obviously, there is an overhead involved having
the DBMS interoperate with external repositories instead of a priori
loading all data into the DBMS. In this paper we discuss alternatives
for interoperability at different levels of abstraction, and we report on
evaluations performed using the Concert prototype system making
these cost factors explicit.
