2. Fire a single query which gets all the data for a specific user and then

from the result set of one single query.
3. Write some stored procedures at database level which will return
aggragted data.

the number of SQL queries increases drastically and which may later on pose
some performance related issues as for every request I would need to run the
above queries.
In second approach I have to write a lot of code...
