We 'll start a project with qlikview and we have 2 solutions :
- Store data in an external datawarehouse
- Store the data in Qlikview database.
Do you know the technical reason to choose the best solution ?
Do you know if there is some technical guide to know the contraints of the tools ?
Thanks for your feedback
The answer is "Yes, but it's not required". A data warehouse definitely helps.
If you don't have the knowledge and the tools to build a datawarehouse, then skip it. If you do have the knowledge and the tools, then I'm sure you know the reasons to use it.
Thanks a lot for this answer.If I understand, there is no reason to use an external datawarehouse. I had heard, it'll be better to manage a big Data Volume and Historical data, for the data integrity ...Qlikview is a real datawarehouse with a real ETL. What is your opinion ? What is the most important problem you encoutetred on this tool ? Thanks you again for your feedback. Laurence
