Answer:
These are keys frequently used in database design and management. There are seven types of Keys in DBMS and here we'll just review three of them. Please see below.
Explanation:
1. Foreign key matches with a field in one table, and this key is a primary key in a related table. There isn’t any special command, instructions, code, configuration, or table definition you need to execute to officially name or designate a foreign key.
2. Super key matches with a combination of keys within a table that helps identify each record within the table. It has to be unique for all possible values of a relation or row in a specific table.
3. Compound key matches with a unique key formed by the combination of two or more fields because it's probable that each field or column may be not unique by itself within the database. However, when combined with the other field (s) or column (s), the combination of keys become unique.
