### Project background
The company M develops mobile apps and buys traffic. It pays ad networks for app installs. To understand which campaigns are profitable and which are draining the budget, a marketing dashboard is needed: a single table that consolidates advertising costs and the revenue these campaigns have generated. Right now, this data is spread across four separate tables and isn’t linked.

### Your assignment
Link separate tables together. Create a marketing dashboard – a single table that shows which advertising campaigns are profitable and which are not. Using this dashboard as a basis, build a Tableau dashboard with several visualizations of your choice. It’s very important to describe your entire calculation process in as much detail as possible.

### Additional information

Table contents:
* non_org_installs_report – installations of an app from advertising sources;
* cost_table – advertising costs;
* ad_revenue_raw – in-app advertising revenue;
* in_app_events_report – subscriptions, purchases, and related events.

Data period: June – July 2026.
