Abstract

Database caching supports declarative query processing close to the application. Using a full-fledged DBMS as cache manager, it enables the evaluation of specific project-select-join queries in the cache. In this paper, we propose significant improvements and optimizations – as compared to the well-known DBCache approach – that make our caching concept truly adaptive. Furthermore, we describe an adaptive constraint-based cache system (ACCache) relying on middleware components as a DBMS-independent realization of this approach.
