1. An adaptive query handling method comprising: receiving an initial query in a database driven application executing in a host computing platform; parsing the initial query to identify a query expression key; matching the query expression key to an adaptive query expression, the adaptive query expression specifying a data query in addition to annotations indicating points of variability in the adaptive query expression, each annotation being replaced with a static sub-expression consistent with a configured query language for a final query expression; transforming the adaptive query expression to the final query expression through a replacement of the annotations in the adaptive query expression with static expressions conforming to the query language for the final query expression; and, applying the final query expression to a database subsystem for the database driven application.
