ETL process evolution is investigated below. A model-driven approach to templates and ETL process evolution problem is developed. We suppose that the ETL process evolution probain...
High complexity of lattice construction algorithms and uneasy way of visualising lattices are two important problems connected with the formal concept analysis. Algorithm complexi...
Several native approaches to storing large XML data sets exist. In all of these approaches the internal data representation is designed to support any ad-hoc XQuery query. In this...
Element constructor is one of most expensive operations of the XQuery language as it requires deep copy of the nodes which make up the content of the constructed element. In this ...
As XML has become a standard for data representation, it is inevitable to propose and implement techniques for efficient managing of XML data. A natural alternative is to exploit...
