Melissa, The most important point is to understand the need and scope of the report data.
* Are we going to use current data (say data for last one year) for our reporting? * Are we going to use history data (say data for last 4 years) for our reporting? * Do we need detail data in our reports? This is used by the user for further analysis as they feed this data in their database and can create one more level of reporting on this data. The format for such reporting is generally .csv or .xls. * Do we need summary data in our report? This is used directly by users and is generally in the form of .pdf. In general, I would prefer to go with below plan. 1) Separate database (Separate from OLAP/ ITSM database) 2) Current data ( Say Last 1 Years Data) a. Summary Data tables for summary reports (generally report in .pdf format) b. Detail data tables for Detail reports. (Generally .csv or .xls format) 3) History Data ( data prior to current data.). This is to be used in rare cases. Maintaining History/Summary tables etc depend on our data volume. In case of reporting where data is pulled directly from ITSM form tables without any need of join forms, it is fine to go with ITSM database. But in cases where report pulls data from different form, needing join forms, it is better to use different database. This helps in following ways. a. Ease of creating join tables. b. Creating Complex procedures. These help reduce burden on reporting tools as most of the complex part is done on database side only. Hope this helps to serve you purpose.

We are looking into how best to architect our reporting and archiving needs. I'm trying to get a feel for what other organizations do for these two processes. Separate databases? Out of the box reporting? Analytics? Separating reporting server (either database or front end)? We are using Oracle 10g and ARS 7.1 with ITSM 7.0.
