Abstract

The huge amount of data available on the Web creates a great demand for methods and tools that allow the manipulation of such data. Thus, the notion of view as a mechanism for providing access to Web data has been revisited. In this paper, we present an environment composed of a set of high-level tools that allow the fetching, extraction, integration, and refreshing of Web data. Using this environment, database designers can build and maintain Web views by defining schemas for data integration, specifying wrappers (agents for collecting Web pages and extracting data from them), and defining plans for refreshing the view contents.
