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 ...
Issues related to updating data in native XML database systems are studied extensively nowadays. In this work we consider a problem of updating typed XML documents having their sc...
In this research we introduce the problem of the binary matrix partitioning in a biological context. Our idea is to use SNP matrix to construct a set of phylogenetic networks to r...
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...
Full-Text XML search is a difficult problem due to its structural and textual constrains. The latter being individually well explored topics, lack mechanisms of integration with e...
