There are four parts to reporting - Reports, Dashboards, Folders and Report Schedules.
Reports are individual aggregates of data that can be displayed as a table or chart.
Dashboards are groups of reports arranged in a customisable grid.
Folders are where you can store your Reports and Dashboards.
Schedules are where you can schedule a report to periodically be sent via email.
You can customise each of these elements to suit your reporting needs.
