چکیده
We investigate data organization in the World Wide Web In order to extend traditional database techniques to the Web we concentrate on structured Web servers those servers now very common in which data are organized according to precise structures and pages present strong regularities The paper introduces several tools for the management of structured servers We present a page oriented data model called the Araneus Data Model inspired to the structures typically present in these servers The model allows us to describe the scheme of a structured server in the spirit of databases Then we develop a view de nition language called the Araneus View Language based on the notion of navigation in the scheme It has two features rst it allows to build relational views of the Web which can then be queried using any relational query language second it allows the de nition of derived Web structures from relational views This can be used to restructure query results and access them as an hypertext or to build derived servers

In a recent paper, Khojasteh emph{et al.} [F. Khojasteh, S. Shukla, S. Radenovi'c, A new approach to the study of fixed point theorems via simulation functions, Filomat, 29 (2015), 1189-–1194] presented a new class of simulation functions, say $mathcal{Z}$-contractions, with unifying power over known contractive conditions in the literature. Following this line of research, we extend and ...
