Data Warehouse Schema

Hi there,

Could someone please explain the meaning of the Size Increase and Size Decrease fields of the Change table within the SCM snapshot? How is it that there may be both an increase and decrease at the same time?

Thanks,
Dawn

If you add file1 and remove file2, that will cause a size increase and size decrease. If you want the overall increase and decrease, then combine both:
E.g.,
increase = 7 decrease = 9 is equivalent to increase = 0 and decrease 2.

This will basically allow for asking questions like:
- how many bytes are being added.
- how many bytes are being removed.

Thanks!

Also, could you tell me if there is anyway to count the changes in Kloc (or something similar) rather than in bytes?

At the moment (for 1.0) we don't have a loc metric - this turns out to
be a much much more difficult thing to compute than byte counts. We will
investigate this after 1.0, as we've had other requests for it as well.
