Mapping OCL into SQL: challenges and opportunities ahead

In this paper, we discuss some of the challenges and opportunities that arise when mapping OCL into SQL. For the challenges, we review the past proposals, evaluating their key design decisions and limitations. For the opportunities, we highlight the key role that OCLto-SQL code-generators can play in model-driven software development. By no means we pretend to exhaust the subject: other challenges and opportunities can be identified and brought up. Our present goal is to stir up again the discussion on this subject among the OCL community.
