I guess at some level I would like to avoid getting the sales pitch and work directly with timesten technical people.
I am curious in finding out, if timesten pre-sales is able to do a deeper analysis and provide information if timesten makes sense for our web and BI applications. Examine our schemas and application architecture. What is the level of their involvement?
Oracle presales consultants work in a team with sales, so I think you should include sale person in this project. I know it because I worked for Oracle. :) but anyway you can contact with technical consultant directly.
Regarding deeper analysis, it is really depends on consultant' s qualification and knowledge. When I worked for Oracle CIS, I did this kind of expertise( architecture and application analysis, POC and etc.). I think there are a lot of people who can do it in US. Please contact the local Oracle office and ask them.
