Antidiuretic hormone (ADH, vasopressin) is produced by the supraoptic and paraventricular nuclei of the hypothalamus and travels in the axons through the pituitary stalk to the posterior pituitary gland.
What is a foreign key in SQL Server? A foreign key is a way to enforce referential integrity within your SQL Server database. A foreign key means that values in one table must also appear in another table. The referenced table is called the parent table while the table with the foreign key is called the child table.
A primary key is either an existing table column or a column that is specifically generated by the database according to a defined sequence. The primary key concept is critical to an efficient relational database. Without primary key and closely related foreign key concepts, relational databases would not work. Almost all individuals deal with primary keys frequently but unknowingly in everyday life.
