An adaptive caching algorithm, known as Adaptive Caching with Multiple Experts (ACME), has recently been presented in the field of web-caching. We explore the migration of ACME to the database caching environment. By integrating recently proposed database replacement policies into ACME’s existing policy pool, an attempt is made to gauge ACME’s ability to utilise newer methods of database caching. The results suggest that ACME is indeed well-suited to the database environment and performs as well as the best currently caching policy within its policy pool at any particular moment in its request stream. Although execution time increases by integrating more policies into ACME, the overall processing time improves drastically with erratic patterns of access, when compared to static policies.
