【 摘 要 】

This paper is divided between two volumes of the review. The introduction presents some of the general principles of database (DB) systems. The rest of the text addresses certain mathematical and technical aspects of the relational DB systems. In the introduction, DB systems are described as programming tools and the notion of DB machine is introduced. The following chapters formally describe the steps to design a skeleton of a relational DB machine. The last chapter examines the expressive power of the tool previously described. Because of its elegant simplicity, the advances it made possible, and its wide diffusion, the relational case has a special place in the DB discipline. It is, in some ways, representative of the DB methods. This article presents only a limited part of the wide range of theoretical and practical knowlege covered by the relational case.
