Network Query Language (NQL)

Front Cover
John Wiley & Sons, Jul 11, 2002 - Computers - 688 pages
Learn about an exciting new technology that is revolutionizing network and Internet content delivery

As the first pure language of the content engineering era, Network Query Language (NQL) is the ultimate tool for rapid and simple development of intelligent agents, bots, spiders, middleware, and scalable business-to-business content aggregation applications. Written by the inventor of NQL, this book explores this revolutionary new scripting language that makes it astonishingly quick and easy to aggregate, analyze, interpret, and redistribute information via networks. Pallmann offers developers and network administrators an insightful look at what NQL is, how it works, and how to use and make the most of its many features. He uncovers the powerful building blocks included in NQL, the vast majority of which are not available in most other programming languages. In addition, he provides details on how to take advantage of NQL's unparalleled ease of use, lightning-fast development, and sheer power.

This comprehensive book defines NQL and examines the broad range of functions that it provides, including:
* Agent communication and synchronization
* Bayesian inference
* Database support (ODBC, OLE DB, ADO)
* Directory server support (LDAP)
* E-commerce (credit card processing)
* HTML pattern matching
* Web application support
* Web site crawling and downloading
* XML parsing

The CD-ROM includes a 60-day trial version of NQL in both Windows and Java (Linux and Macintosh) formats.
