Footnotes_values

Summary

This table provides information regarding the relationships of the values of their measures and the footnotes that need to be associated with them. This table links both the 'measures' table and the 'entity_values' table to the 'footnotes' table.

This table uses all five fields to create a concatenated key to keep track of unique entries. These five fields are measure_id, entity_id, date_start, date_end, and footnote_id. Duplications can exist in this table for any of these fields, but all five can never be exact matches.
