Data level's integrated model for the national grid company's decision support system

This paper presents some results of a research project regarding the possibilities of integrating various data sources from multiple measuring systems existing in the Wind Power Plants in Romania. We consider XML as a format for receiving data, object-relational model with spatial capabilities for data management and representation and JDBC for data access. Thus, a data level's architecture can be developed in order to query data through data mining, multidimensional or spatial analysis.
