From: Search extension transforms Wiki into a relational system: A case for flavonoid metabolite database
A) Correspondence between relation table in RDB and pages in MediaWiki;. One tuple corresponds to one page whose title is the primary key. Together, pages in the same namespace constitute the original relation table. In Wiki pages, attributes are separated by user-defined separator symbols. In this example, && is the separator. B) Basic schema of flavonoid database; A table for reference information connects tables for metabolite and plant species. The link is used for Metabolite-Species table in Wiki pages.
