An architecture for automatic relational database sytem conversion
Ben Shneiderman, Glenn Thomas · ACM Transactions on Database Systems · 1982

An alternative to the lengthy manual revision process is proposed by offering a set of 15 transformations keyed to the relational model of data and the relational algebra. Motivations, examples, and detailed descriptions are provided.
