US Patent 8402061 Tiered middleware framework for data storage

A tiered middleware framework for transacting data between an application layer and a data storage layer includes modular components. The tiered middleware framework is implemented when the arrangement of the modular components enables the tiered middleware framework to meet or exceed certain data transaction criteria. However, when the data transaction criteria are not met by the tiered middleware framework with arrangement of the modular components, the modular components in the tiered middleware framework is rearranged.
