Question: What is the name of the corporate customer from Rhode Island who had the highest number of orders in 2016 from the east superstore?
Evidence: corporate customer refers to Segment = 'Corporate'; Rhode Island refers to State = 'Rhode Island'; in 2016 refers to "Order Date" BETWEEN '2016-01-01' AND '2016-12-31'; east superstore refers to Region = 'East'; highest number of orders refers to max(order_number); name of corporate customer refers to "Customer Name"

SQL:
SELECT T2.`Customer Name` FROM east_superstore AS T1 INNER JOIN people AS T2 ON T1.`Customer ID` = T2.`Customer ID` WHERE T2.Segment = 'Corporate' AND T2.State = 'Rhode Island' AND T2.Region = 'East' AND STRFTIME('%Y', T1.`Order Date`) = '2016' GROUP BY T2.`Customer Name` ORDER BY COUNT(T2.`Customer Name`) DESC LIMIT 1
