Hi,
I have got requirements to develop a complete BI Solution. As per requirement for each city will have 100 records for every month and there are 3000 cities, so there will be 3lac records for every month correspondingly 36lac records for 1year. We should maintain 3yrs of data in DB which will have 1.08cr of records.
Business required reports at each level of hierarchy, some times report has to fetch data from lowest granular level i.e. City. For this kinda requirement we can have cube to increase the performance but again if we have to maintain at lowest granular level data i.e..3.08cr records of data in cube will it really help me in fetching data faster when compared to RDBMS?
Please suggest me something or give me a solution if you have any?
Thanks for your help.
Regards,
Bharadwaj Sastry.
