Dear BIRT users,

I am using eclipse BIRT to produce a lot of reports. To be more effective I am using rptlibrary to share data sources and themes. There are the following questions I have regarding using rptlibrary in the best possible way:

1) Is it a good idea to have all the datasets defined in one rptlibrary file?
2) If yes, is there any performance issue with final reports if there is a lot of data sources and datasets (e.g. 60 datasets created from 5 different data sources)?
3) Do you also share data cubes and/or other objects in rptlibrary?
4) Should I have data definition and styles (themes) definition in one or more rptlibrary files?
5) Do you have any other recommendations on rptlibrary topic?

From a run perspective the number of datasources and datasets does not
matter much. It depends on how many of these datasets actually execute.
That will be the main impact. That said the rptlibrary will be loaded
by the engine when the report is loaded, which will use more time at the
front-end of running a report. I am not sure of the actual numbers but
60 seems like a lot.

BTW I use libraries for data cubes and styles as well.
