There are broadly two different types of variables in SSIS. They are:

  • System Defined: SSIS provides a set of system variables to store the information regarding running packages and objects. They are generally used in expressions and property expressions to customize containers, event handlers, packages, and tasks.
  • User-Defined: These types of variables can be configured by the user in a way that its value can be updated at the run time, or the value can be assigned by the user itself at the time of creation.
