Abstract
A method and apparatus for processing data using multi-tier caching are described. In one embodiment, the method includes receiving a user request containing one or more data parameters and searching cache memories of multiple tiers until finding a parameterized result set associated with the data parameters. The multiple tiers correspond to stages in the transformation of data retrieved from one or more data sources according to the user request. Once the parameterized result set associated with the data parameters is found, it is used to create a final result set.
