Need help in computing and reporting data, which is collected every minute for each database. First column is Server name, Second column is Time having format(+%Y-%m-%dT%H:%M:%S%z), Third column is Database name and Last column is amount of MB/sec performed by each database.

Snippet of data: 

server01: 2015-06-01T12:40:03-04:00  DB101                  10 MB/sec

And I want to report it in two ways as shown below, please note that I am not bothered about grouping at Server names, Its just grouping MB/sec for each Database name and I want to do it at Minute and Hour level.

Sample of Required output: 

Frequency Minute:
           collectionTime DB101 DB202 ASM MYDB101 MYDB202 _OTHER_DB_
2015-06-01T12:40:03-04:00   100    14   4       5       6        140  
2015-06-01T12:41:03-04:00     4     8   4      16      14        105
