Functional querying in graph databases

open access: yesVietnam Journal of Computer Science, 2017
The paper is focused on a functional querying in graph databases. We consider labelled property graph model and mention also the graph model behind XML databases. An attention is devoted to functional modelling of graph databases both at a conceptual and

Independent database schemas

open access: yesJournal of Computer and System Sciences, 1982
A database schema is independent with respect to a given set of constraints if the constraints can be enforced separately in the relations. A polynomial-time algorithm is presented that recognizes independent schemas, when the given constraints consist of functional dependencies and the join dependency of the database schema.

The theory of relational databases has much in common with the mathematical structures central to the Z notation. Many authors have noted these connections in the past, but the development of the Z standard has provided a more natural way of making these links explicit.
