During this session, we will show you how to add a Derived Table to your Data Source and pull in those specific data points (i.e. groups, cohorts, etc.) or custom fields. You may also want to use a Derived Table to write your own SQL for your own reports. This is an advanced topic for Zoola Analytics.

Data Connections Data Sources Ad Hoc Views Reports Dashboards
This is the definition of the connection to your database.
Only visible when you are creating Data Sources.

5. The Zoola Information Hierarchy

Data Connections Data Sources Ad Hoc Views Reports Dashboards
A metadata layer that provides a clean view of the
database. A Data Source allows you to control access to
the data based on security permissions.

Data Connections Data Sources Ad Hoc Views Reports Dashboards
An Ad Hoc view is used to explore, analyze, and
visualize the data provided by the Data Source. Ad Hoc
Views are used to create Reports and Dashboards.

Reports are finalized versions of Ad Hoc Views intended for
presentation and analysis purposes, allowing stakeholders
to interact with data and export the final result.

Dashboards combine Reports to deliver an at-a-glance and
interactive summary of information for users to view the
state of their Learning.

Derived Tables
A derived table is a table expression that
appears in the FROM clause of a query.

SELECT d.userid AS userid,
MAX(CASE WHEN f.shortname = 'gender' THEN d.data ELSE '' END) AS Gender,
MAX(CASE WHEN f.shortname = 'state' THEN d.data ELSE '' END) AS State
FROM mdl_user_info_data d
JOIN mdl_user_info_field f ON d.fieldid = f.id
GROUP BY d.userid
NOTE :: LEFT JOIN mdl_user.id = der_uf.userid
