Abstract: The present disclosure proposes the method for optimizing the performance of data base/web-service backed applications by automatically prefetching query results. The proposed system and methods automatically insert prefetch instructions at the earliest possible points across procedure calls in application source code, in presence of conditional branching and loops. A data flow analysis technique called anticipable expressions analysis is extended, to analyze anticipability of queries. The benefit of prefetching is limited due to the presence of assignment statements and conditional branches that precede the query execution statement. Enhancements such as code motion, chaining and rewriting prefetch requests are devised to increase benefits of prefetching. These techniques perform equivalence preserving program and query transformations.
