Hi @Shruti1 ,
Following is the definition of your concerned terms:
Targeting Wkfs: Targeting workflows enable you to build several delivery targets. You can create queries, define unions or exclusions based on specific criteria, and add scheduling, thanks to workflow activities. The result of this targeting can be transferred automatically to a list that can serve as the target of delivery actions
Campaign wkfs: For each campaign, you can create workflows to be executed from the Targeting and workflows tab. These workflows are specific to the campaign. Campaign workflows enable you to create and configure deliveries entirely for all available channels. Once created in the workflow, these deliveries are available from the dashboard of the campaign.
Technical wkfs: Technical workflows are provided out-of-the-box with Adobe Campaign. They are operations or jobs scheduled for periodic execution on the server. They let you carry out maintenance on the database, forward tracking information on deliveries and set up provisional processes on deliveries. Technical workflows are configured via the Administration > Production > Technical workflows node.
