Symbolic modelling of database representations

The paper proposes a symbolic model for tackling the theoretical basis of the transformations between the relational database form and its XML representation. The model we propose aims at proving the consistency of such transformations, which are often used in software applications that process databases. On a more abstract level, our aim is to show that the categorial theory developed in symbolic computation can offer tools for systematically tackling the basis of fairly complex problems which rise in software design.
