Abstract: An electronic catalogue is implemented on a server computer by a software component which functions as a catalogue system and an associated database. The catalogue contains details on a set of individual products. The database contains a set of tables, which contain data items relating to the products. A set of first, second and third order templates are also stored in the database. Each second order template is subordinate to an associated first order template and each third order template is subordinate to an associated second order template.

The catalogue contains details on a set of individual products. The database contains a set of tables, which contain data items relating to the products. A set of first, second and third order templates are also stored in the database. Each second order template is subordinate to an associated first order template and each third order template is subordinate to an associated second order template.
