DAP, the Data Action Platform, lets your end users, administrators, and developers perform data modification actions in bulk. Give end users access to bulk actions anywhere in your Salesforce org by adding a button to mass edit from list views, and limit this access per user profile.

DAP is starting off with a number of out-of-the-box actions such as Mass Update, Mass Delete, mass Create Tasks, and Mass Convert. Execute these actions from a list view, as a single or scheduled job, or when triggered by a specific event. Use macros to execute recurring actions with predefined values. Apply the out-of-the-box features, or define your own actions and triggers.

In the future, more actions and other features will be added.
