Next Generation Database Programming and Execution Environment

The database research is always on the move. In order to integrate novel concepts, the significance of the database programmability aspect more and more increases. The programmability aspect focuses on internal components as well as on principle to push-down application logic to the database system. In this paper, we propose a novel database programming model and a corresponding database architecture framework enabling extensibility and a better integration of application code into DBMS. In detail, we present a scripting language pyDBL which is unified utilizable to implement physical database operators, query plans and even complete applications. We demonstrate the applicability of our approach in terms of a moderate performance overhead.
