How is Data "Analysis" different from plain reporting : AKA Synopsis writing

When we send out reports. We are more often than not in “URGENT” mode. Unless or until mentioned we never send any insights to the person who requested the report/analysis. It may be a very “SMALL” step to write your “UNDERTANDINGS” as synopsis, but doing it consistently has three benefits.

1. You will know what is the report saying and hence understand the business
2. You are virtually doing a self QC.
3. You are creating a “BRAND” for yourself with some important insights/actions that you share.
4. When writing synopsis, you be bold. You are NOT writing it to please the other person. Clearly mention what you speak in mind.

Now the big Question you guys have is. We are looking at this data from long time. What new can I see now. That’s when you come out your report and try to co-relate other aspects of business. 

Remember writing synopsis will improve your Professional value, IMPROVE your personal accuracy and self-satisfaction. Trust me when I say this. It’s a very intensive activity but it is one of the best teachers you can get.

ROLLUP function: How to get sub total row in a Oracle SQL query as output

 In oracle SQL query when you query for any data, the output is table of columns and rows selected. But there is not total added at the bottom.

How to add a total at the bottom and also how to add a sub-total for each change of value in a specific column.

select fruits, city, sum(price) from fruits_table group by rollup (fruits,city)

In the above example the table a total will be added to FRUITS level and also a sub-total will be added at each change in CITY.

However, there is catch. If there is more than one dimension (in the above example FRUITS & CITY) then you should sort the table by CITY and Fruits so that the sub-totals appear in order. Below the updated version of the example query with ordering.

select fruits, city, sum(price) from fruits_table group by rollup (fruits,city) order by city,fruits
