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.

Why it's free to use
- Filed July 28, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 28, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 28, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
