Rosetta

Abstract

Adata language is adeclarative language that enables database users to access and manipulate data. There are families of related data languages, each family member targeted for a particular application. Unfortunately, building compilers for such languages is largely an ad hoc process: there are no tools or design methods that allow programmers to leverage the design and code of compilers for similar languagea, or to simplify the evolution of existing languages to include more features. Rosetta, a generator of relational data language compilers, offers solutions to these problems. We explain how domain analysis identifies primitive building blocks of these compilers, and how grammar-based definitions (~la GenVoca) of the legal compositions of these blocks yields compact and ertsily-evolvable speci- SciencesThe University of Texas at Austin Austin, TX 78712fications of data languages. crates compilers from such with Rosetta are discussed.
