What's the Difference Between Batch Management and Batch Apex?

Batch Apex requires admins or developers in your Salesforce org to write lines of code to automate the processing of large volumes of records. Conversely, Batch Management doesn't require a single line of code. It can be set up and maintained with only a few clicks in your org's user interface. Batch Management also helps you to monitor the batch jobs. Batch Management allows you to run multiple batch jobs as part of one scheduled flow.
