This question runs in a pre-configured Salesforce environment - no personal connection required.
Write a method that creates a comprehensive contact report for multiple countries. The method should take a List of country names and return a Map<String, Map<String, Object>> where:
- The outer key is the country name
- The inner Map contains: 'contactCount' (Integer), 'totalRevenue' (Decimal), 'avgRevenue' (Decimal), and 'topContact' (String with name and title)
This advanced challenge tests your ability to combine complex SOQL queries, data aggregation, nested Map structures, and mathematical calculations across multiple objects and countries.
Examples
Input: countries = ['USA', 'Germany', 'Japan']
Output: {
'USA' => {
'contactCount' => 12,
'totalRevenue' => 450000000.00,
'avgRevenue' => 37500000.00,
'topContact' => 'David Thompson - Founder'
},
'Germany' => {
'contactCount' => 1,
'totalRevenue' => 75000000.00,
'avgRevenue' => 75000000.00,
'topContact' => 'Hans Mueller - Operations Director'
},
'Japan' => {
'contactCount' => 1,
'totalRevenue' => 65000000.00,
'avgRevenue' => 65000000.00,
'topContact' => 'Takeshi Yamamoto - CTO'
}
}
Explanation: Returns comprehensive country-level contact and revenue analysis
Input: countries = ['NonExistent']
Output: {}
Explanation: Returns empty map when no data exists for the countries
