multiple data sources

[Former Member]

Hi,

I need to create a Crystal report which links to multiple data sources, i have two options:

1. link multiple data sources from Crystal reports;

2. Create a Universe which has multiple data sources, use this Universe as the data source for my Crystal reports;

From performance point of view, which way will be better? Why?

I guess connecting to multi-source Universe will be better, what's your thoughts?

Thanks

If you can link them in CR Designer it's always the best.

The best solution is to do it all Server Side, Create a Store Procedure, this way all of the filtering and data collection is done on the server which is much more efficient at collecting data than CR will ever be. Then it's just the final data collection being sent to CR, less network traffic and local resources to process/filter the data.

Another option is to use a subreport for each unique data source.

Or some DB's also have the ability to link multiple data sources together and create a View.

If you are going to use a Universe then it requires BOE to be available also which could limit your distribution abilities.
