A Unique Key Index is an index in which there are no duplicate keys. With such an index, every key points to one and only one record.

For example:

  • In a Case Management system, every case number is unique.
  • In an index of companies, every company name is unique.
  • In a list of U.S. citizens, every social security number is unique.
