Metaprogramming for Relational Databases

For systems that share enough structural and functional commonalities, reuse in schema development and data manipulation can be achieved by defining problem-oriented languages. Such languages are often called domainspecific, because they introduce powerful abstractions meaningful only within the domain of observed systems. In order to use domain-specific languages for database applications, a mapping to SQL is required. In this paper, we deal with metaprogramming concepts required for easy definition of such mappings. Using an example domain-specific language, we provide an evaluation of mapping performance.
