A sequence may refer to any of the following:

  1. A sequence is an ordered list containing successive items, or functions for performing certain actions.

  2. In an SQL database, a sequence is used to generate a unique number and starting point, which is then increased based on a set interval. A sequence is often used to create a primary key value in a database table, and is incremented by one with each newly generated database entry.

  3. Upon startup, computers utilize what is called a boot sequence. See our boot sequence for further information on this term.
