Texhtml Workshop

Aims

To introduce attendees to the Texhtml World Wide Web gateway interface for Texpress databases. This module enables users to publish their databases on the Internet or on an Intranet within their own organisations.

Format

This course is a two-day workshop. Each attendee has exclusive access to a PC or to a Unix host on which Texpress is installed. The PCs and Unix host operate as an Intranet, while the entire network also has a gateway to the Internet. Attendees develop and test a range of query interfaces on their own databases and run Netscape (or similar browser) interactively to test their designs.

Prerequisites

This course assumes that attendees have completed the Texql training course. Familiarity with Unix and a Unix editor is essential and the capability to develop simple shell scripts is desirable.
