Recent advances in the underlying architectures of DataBase Management Systems (DBMS) have motivated the redesign of key DBMS components such as the query optimizer. Optimizers are inherently difficult to build and maintain, and yet there exists no software engineering tools to facilitate their development. In this paper, the authors introduce a (Devel)opment environment for query (Op)timizers (Devel-Op) designed to facilitate the rapid prototyping, profiling and benchmarking of optimizers. Their current version of the tool permits declarative specification and generation of two key optimizer components (the logical plan enumerator and physical plan generator) as well as debugging and visualization tools for profiling generated components.
