What is the criteria to decide on Extraction vs Report (ing)

[rrbhupathi]

Hi,

Most of our reports generates more than 100K of records at the participant level;

Our thought is in those scenario's users should use Data Extraction tools like Informatica instead of extracting the data through reporting tools like Cognos;

I am trying to get clear on what should be the criteria to decide on whether to use Data Extraction tool vs reporting tool;

Appreciate if somebody can throw some insights on this topic


Thanks

In what context? Are these reports against a data warehouse or an operational system?

If it is against a data warehouse, what advantage do you believe you would gain if you did an extraction? A report is an extraction. What's the difference?

If you are talking about an operational system, then you may consider creating a data warehouse. The decision to actually build a data warehouse would usually occur after there have been serious problems with users running very large reports while the rest of the company is trying to conduct business.
