DHIS2 generates database tables which the system then uses as basis for various analytics functions. These tables are also valuable if you write advanced SQL reports. In the Data Administration app, you can execute the tables generation immediately. If you want to schedule them to be executed at regular intervals, this can be done in the Scheduler app. This means that you can refresh recent analytics on demand and see updated pivot tables without waiting for all of the past years data to re-process.
You can also generate the tables through the web API. This task is typically performed by a system administrator.
