On the existence of acyclic views in a database scheme
1985
Theoretical Computer Science
The importance of acyclic database schemes in relational database theory has been pointed out in various contributions in the literature. Unfortunately, the realm of interest which is captured by the database scheme is often intrinsically cyclic; therefore, we are faced with the problem of finding acyclic views on such a scheme. In this paper we consider three kinds of acyclicity, called a-, 7-and Berge-acyclicity by , and we approach the problem of the existence of acyclic views in a database
