MySQL Workbench was used to create schema diagrams for the core database.
In case of schema changes, update the relevant diagram and regenerate the diagram pdf.

To regenerate core_schema.html use script sql2html.pl in ensembl/misc-scripts/ with the following options:

-i (sql file name) table.sql
-o (html file name) 
-sort_headers 0 (1- sort in alphabetical order)
-sort_tables 0
-d (database) Core

Follow instructions in file html_to_append.html to complete the generated HTML and save as core_schema.html.
