Abstract

The selection of a proper set of operations for a database machine has a great influence on the performance of the overall system. In this paper, we will discuss the data language requirements of database machines. The data language for a proposed relational database machine is presented. Methods for supporting hierarchical and network interfaces using a relational database machine language set are introduced. The relative performance for data access using relational and network interfaces is compared through the evaluation of cost functions. It is shown that the support of a network interface in a relational database machine is feasible, but expensive.
