XML based mediation for automating the storage of SCP-ECG data into relational databases

The aim of this paper is to present a generic mediator for automating the storage and retrieval of an SCP-ECG message into and from a relational database. The architecture of the mediator is based on the XML technology and its related languages and derivatives (XML Schema, XSLT...), which provide powerful tools for sharing, converting and exchanging information. The adopted methodology consists in the design and in the interconnection of meta-models of the source and target data representations using the XML language. The SCP-ECG format is easily represented in XML, whereas the database meta-model must be appropriately created according to a tree structure by reverse engineering. Then, our method includes a rule base allowing a coherent and secure mapping between the source and the target data for ensuring the database integrity.
