help a new user choose NxD? (how large volumn can Xindic handle?)

Dear all

I am choosing NxD for my project. The NxD is used mainly as an XForm  
repository to store a lot of XForms submitted by a lot of people. The  
choice must be very careful because

1-> The data volumn is big. The system will start with 400,000 XForms and  
probably double or tripple in the coming years. Each XForm can have  
several dozens of values in it (some XForms have several hundreds of  
values in it);
2-> Advanced query feature must be implemented, it's often needed to  
calculate from tens of thousands of records on average value of a certain  
elements for example.

I guess the second question is more or less related to XQuery and how  
flexible it can achieve, and compare with project requirement. The first  
question is probably depend on how NxD can handle. Can Xindic easily  
handle data at this volumn? Which NxD can do?

If Xindic is chosen and helped us succeed, because the project, once done,  
is pretty open to the outside, this will be a good success story for  
Xindic for marketing purpose too:) We would like to share victory with  
apache team!
