Introduction to Custom Tables
As the Firepower System collects information about your network, the Firepower Management Center stores it in a series of database tables. When you use a workflow to view the resulting information, the Firepower Management Center pulls the data from one of these tables. For example, the columns on each page of the Network Applications by Count workflow are taken from the fields in the Applications table.
If you determine that your analysis of the activity on your network would be enhanced by combining fields from different tables, you can create a custom table.
Note that you can create custom workflows for either predefined or custom tables.
