Which of the following can be used as supported pre- or post-processing commands?

The correct choice encompasses all listed options, highlighting the flexibility and versatility of Informatica Cloud Data Integration in handling data processing tasks.

Pre- or post-processing commands are vital in data integration workflows as they allow for additional operations to be performed either before or after the primary data processing tasks. Using SQL commands can facilitate database manipulations, allowing operators to prepare or update data efficiently within the database itself. Furthermore, leveraging valid DOS or batch files can automate repetitive tasks in a Windows environment, streamlining workflows. Additionally, Unix commands can be incorporated for users operating in Unix-based systems, enabling a broad spectrum of command-line tools to be utilized effectively.

By allowing all these command types, Informatica provides users with numerous options suitable to different environments and use cases, enabling an adaptable and efficient integration process. This multi-faceted approach enables users to customize their workflows according to their specific business needs.
