Evolving Source Interfaces over the Web
نویسندگان
چکیده
Data sources over the Web publish their query interfaces through forms or templates. Over time, the set of templates supported by a source changes due to new requirements or enhanced query-processing capabilities. When a new template is being considered for a source, it is important to verify whether the new template is redundant with respect to the existing set of templates being supported. This veriication avoids redundant templates and keeps the query interfaces simple. In this paper, we study the problem of verifying if a given template is redundant with respect to a given set of templates. We develop eecient algorithms to solve the problem.
