- Configuration variables
  A configuration variable defines an alias that resolves at run time to a value that is specific to a deployment environment. A deployment environment is represented by a server group. By associating the values of a configuration variable with different server groups, you can run the same map or flow in different environments, servers, and platforms without changing the map or flow.
- Flow variables
  Flow variables provide a means of passing information throughout a flow instance without requiring that the information to be passed through data links. flow variables are name-value pairs that persist, unless deleted.
- Cache variables
  Cache variables provide a means of processing information throughout a flow instance without requiring that the information to be passed through data links.
