Adding a relational interface to a nonrelational database

Abstract

Today, thanks to more powerful machines and more robust data models, relational databases have gained broad industry acceptance. As relational databases grow in power and popularity, developers face pressure to convert legacy databases to this newer model. The author proposes a technique for doing so efficiently. The approach involves a bridge program that adds a relational software layer atop the nonrelational database management system. The interface translates the relational database management language into the nonrelational database management language to access the existing nonrelational database.
