Introduction to Environment Variables
Environment Variables are optional, static configuration information that is attached to specific Environments.
Environment Variables are used for storing information used in a Process. A typical example of an Environment Variable is a username, password, or a connection string needed to access the source or target system. The kind of information stored in Environment Variables, as well as their purpose, is not limited.
When designing the implementation of a Process, Environment Variables are one topic you should consider. Once the Process design identifies the needed Environment Variables, you can create them in the Environment Variables View. After the Environment Variables have been created, you can provide values to the variables in the same View. Whenever there is a need to update the variable value, for example, in the case of a changed password, the value is updated also by using the Environment Variables View.
Typically, the naming convention of Environment Variable Groups and Variables is defined in your organization's guideline document and the integration design documentation.
The main advantages of using Environment Variables are:
You can simply refer to an Environment Variable in your Process to access the defined variable value.
When you need to update an Environment Variable value, it can be done in one place at the Environment Variables View.
The values of the Environment Variables can be changed without needing to rebuild the Processes using the Environment Variable.
There are different types of Environment Variables you can use:
Group: You can group several Environment Variables in the same group.
List: A list of text-type variables.
Text: A text-type variable.
Number: A number-type variable.
Boolean (Yes/No): A Boolean-type variable.
Secret: A secret-type variable. The value of the variable is not shown in the Environment Variables View.
