RE-USABLE DATABASE SYSTEM

摘要

A database and content management tool for such a database in which the database has a plurality of tables. A service table (100) identifies services having records in the database. Each service has a numbe r of datatables defining (e.g.) item types (109) with direct links to items of the service in a further table (110). Item types are also linked to feature types held in another datatable (115), the linking being performed by a linking record table (116). Feature details are held in a feature detail table (114) linked directly to feature types. Items are linked to feature values by a further linking table (113). Various other tables are linked to items such as Supplier and Media by respective linking tables. The arrangement allows the creation of HTML pages and other kinds of display from the various features either directly accessed from the table or whose location (e.g. in external file servers) in held in hyper datatables (106). A content management tool enabling end-users to update records and create links between unique identifiers (items) and shared data (feature type, supplier, media for example) is provided.
