Environment variables are predefined variable those we can use while creating datastage jobs.We can set in project level or job level once we set the variable the variable will be available in the project.

Enviroment Variables are the one who set the enviroments.
Oce you set these varicables in datastage you can use them in any job as a perameter.

Example is

you you want to connect to database you need userid , password and schema.

These are constant through out the project so they will be created as env variables.

use them where ever you are want with #Var# .

By using this if there is any change in password or schema no need to worry about all the jobs . change it at the level of env variable that will take care of all the jobs.
