UCDB version 1.0
UCDB 1.0 was initial version of the database presented at CEE-SET 2008 conference. It consisted of 432 use cases coming from 11 projects, which are briefly presented in Table 1.
In Table 2, you can find a list of properties we were trying to measure quantitatively. Only the average values are presented here. If you are interested in details you can find them in the paper. You can also look at the next editions of the database.
