Information Aggregation Using the Caméléon# Web Wrapper
[chapter]
2005
Lecture Notes in Computer Science
Preserved Fulltext
Caméléon# is a web data extraction and management tool that provides information aggregation with advanced capabilities that are useful for developing value-added applications and services for electronic ...
This paper covers the integration of Caméléon# with commercial database management systems, such as MS SQL Server, and XML query languages, such as XQuery. ...
We illustrated the simplicity of use and the power of Caméléon# with the example construction of an application such as the mega airfare aggregator. ...
