Modular method and system for performing database queries |
摘要 |
A query engine residing on computer-readable media includes a library of data drivers and an intelligent dataset. Each data driver in the library is operable to execute a predefined database operation. The intelligent dataset is operable in response to a query request to identify from the library necessary data drivers to perform the request. The intelligent dataset is further operable to determine a necessary order of the necessary data drivers to perform the request, to generate a driver chain comprising the necessary data drivers in the necessary order, and to execute in order the data drivers in the driver chain.
