Deriving structures from structures,ated rules, we need precise and tractable mathematical definitions of rules and how to apply them. This paper presents such definitions and some fundamental theorems, together with brief remarks on applications to record handling, evaluation of recursively defined functions, and control flow analysis for optimizing compilers.

Contribution to the theory of concurrency in databases,se management systems locking logical or physical parts of the database during the execution of each transaction is performed. This solution restricts the degree of sharing. In this paper, a better characterization of possible schedules is proposed. Then, scheduling algorithms avoiding incorrect executions are proposed.

On the completeness of query languages for relational data bases,otion of completeness we have introduced is .. Therefore, for any configuration τ consisting of a binary relation r there exists a formula r. of the first order calculus describing the transitive closure of r, but this formula depends on τ and there is no formula describing the . which associates with a binary relation its transitive closure.
