Abstract
The Distributed Information Search COmponent (DISCO)
is a prototype heterogeneous distributed database that accesses
underlying data sources. The DISCO prototype currently
focuses on three central research problems in the context
of these systems. First, since the capabilities of each
data source is different, transforming queries into subqueries
on data source is difficult. We call this problem the weak
data source problem. Second, since each data source performs
operations in a generally unique way, the cost for performing
an operation may vary radically from one wrapper
to another. We call this problem the radical cost problem.
Finally, existing systems behave rudely when attempting to
access an unavailable data source. We call this problem the
ungraceful failure problem.
DISCO copes with these problems. For the weak data
source problem, the database implementor defines precisely
the capabilities of each data source. For the radical cost
problem, the database implementor (optionally) defines cost
information for some of the operations of a data source.
The mediator uses this cost information to improve its cost
model. To deal with ungraceful failures, queries return partial
answers. A partial answer contains the part of the final
answer to the query that was produced by the available data
sources. The current working prototype of DISCO contains
implementations of these solutions and operations over a
collection of wrappers that access information both in files
and on the World Wide Web.
