Oracle Data Provider for .NET (ODP.NET) enables you to take advantage of features exposed by the underlying Oracle Call Interface. One such feature new in Oracle Database 11g Release 1 and Oracle Database 11g Release 1 Client is the client result cache.
The client result cache is a portion of memory that is automatically allocated (on the client) to cache query results. Caching query results on the client makes it possible to avoid round-trips to the server to execute, query, and fetch data. This, in turn, leads to better performance and decreased resource consumption on the network and the server.
