I am working on good retrieval mechanism for big data systems. I am of view that multidimensional structures could be of great use for aggregations and querying . Multidimensional structures as mentioned in theory/products could replace the need of OLAP CUBE.

Here is some data size info residing into data-warehouse and it is approx. around 1 trillion per month and some time even more and having rolling window of 1 month or greater, it depends per client. I used to write reports,sub-reports and calculate aggregates using sub-reports , and also used analytical and analytical aggregate function to accomplish the reports/query.

Can some one share the thoughts on it.

Regards,

  • $\begingroup$ It is a little unclear what you are asking. When you say big data systems how big do you mean? What types of queries and aggregations are you going to do? $\endgroup$ – Godric Seer Apr 29 '14 at 19:46
