RE: Transformations

Hi,

The people from Excellon (former ODI) have implemented a permanent info set
on a memory mapped object data base. From what I understood, an XML document
is parsed and then stored as an internal structure. This internal structure
is kept in a memory mapped area. Thus, it seems that the only possible
bottleneck here is the page fault that occurs when more than one document is
processed at the same time. I am curious to listen to what the Excellon
people have to say on how they are managing the page fault or how their
stuff compare to other engines (Java and C++ based) for a certain
transformation. I know, that some of the Excellon people are lurking and
sometime participating to the list. So, can you give us some input on this?
This could help us better understand the implementations issues.

cheers
Didier PH Martin
