Introduction
There are three primary document views utilized by the ISFDB: showing the bibliography of an author, showing the titles present in a publication, and showing the publications in which a title was published. These views require three primary tables: authors, titles, and publications. Various normalization tables are provided to reduce errors and storage needs.
The illustration below shows the relationship between the various tables. All notes are stored in the notes table, which other tables refer to via the primary note_id key. There are two tables which are used for administrative and display purposes. The metadata table contains data pertinent to the database itself, while the magazine table contains information that allows magazine publication to be grouped under a single magazine heading.
A high-level explanation of the database can be found in the Database Overview article. An up to date diagram of the ISFDB tables and their relationships can be found here.
