Final answer:
The statement is true; the foreign key is the field in the 'many' table of a one-to-many relationship that references the primary key in the 'one' table.
Step-by-step explanation:
The statement that the linking field on the 'many' side of a one-to-many relationship is called the foreign key field is true. In database relationships, a one-to-many relationship is established between two tables when a single record in one table (the 'one' side) can be related to multiple records in another table (the 'many' side). The way to create this relationship is to include a field in the 'many' table that references the primary key of the 'one' table. This field in the 'many' table is known as the foreign key field. Essentially, the foreign key in the 'many' side table is a reference or link to the primary key in the 'one' side table, ensuring the relational integrity between the two tables.
