Abstract
Abstract A system includes a database system, a user application, an operating system, and a database device driver attached to the operating system, the database system, and the user application, the system comprising. The system transmits a dynamic access request from the user application to the database device driver. The database device driver produces a dynamic access command for transmission to the database system in response the transmission of the dynamic access request to the database device driver. The database device driver receives a response from the database system in response to the dynamic access command transmitted to the database system. The response received from the database system is reformatted into a response for transmission to the user application and transmitted from the database device driver to the user application.
