Abstract
Semantic caching is a technique used for optimizing
the evaluation of database queries by caching results
of old queries and using them when answering new queries.
CoopSC is a cooperative database caching architecture,
which extends the classic semantic caching approach by
allowing clients to share their local caches in a cooperative
matter. Cache entries of all clients are indexed in a distributed
data structure constructed on top of a Peer-to-Peer
(P2P) overlay network. This distributed index is used for
determining those cache entries that can be used for answering
a specific query. Thus, this approach decreases the
response time of database queries and the amount of data
sent by database server, because the server only answers
those parts of queries that are not available in the cooperative
cache.
