coredata

Given a CoreData-Entity with an date (days) and an ammount called Transaction. Is it with CoreData possible (and how) to aggregate/group the 'table' (with all Transactions) by Date and calculate the sum of the day in a second column/attribute? (the SQL-Solution would be SELECT date, sum(ammount) FROM transaction GROUP BY date)
