A range of integrity constraints that can be specified on a schema expressed in the network model of data is presented. These integrity constraints can be of three kinds. The first, called value sets, define values which fields of a record type can take on. The second kind can be specified...

In earlier work, we proposed an integrity constraint mechanism intended to maintain consistency in multiversion databases [6, 5]. However, we did not consider versions of integrity constraints. This paper analyses the extension of this integrity mechanis
In this paper, we propose an efficient technique to statically manage integrity constraints in object-oriented database programming languages. We place ourselves in the context of an extended version of the O2 database programming language, and we assume
