Suppose, we have data like below:
Eid Ename Salary Dept
1.abc 2000 java
2.bbc 3000 .net
3.Krishna 2500 java
Madhu 300
5.Vamshi 3000 mainframes

2 bbc 13000testing

Aggregation: To display aggregate data
Sum/avg salary by each individual employee
Drag ename on column and salary on rows, and we will get the sum (salary) of each and individual employee
Now, change the measure type as Avg
Choose salary option: choose measure types as ‘Avg’
Disaggregation: To display each and every transaction
When we look at the aggregated data in the views above, each bar represents all transactions for a specific employee summed up or averaged into a single value. Now, say, we want to see the individual salary transactions for each employee. We can create a view like that by selecting Analysis > Aggregate Measures.
