The most important thing is that it helps us reduce our code base, as well we can have all of this data centralized into just few tables instead many small ones which was before hardcoded even if they were not used at first sight (like with some older systems).
It's very good tool but I would like better integration between predict system itself so when you are writing your query or report - everything will be done automatically without any manual work from developer side! You get more flexibility than other tools because there isn't predefined structure/schema what should look exactly how database looks after migration process has been performed etc.. I like that predict is not so expensive, it's easy to use (and learn) but also has very powerful features which can be used with various languages such as Java or C/C++ etc., It would have been great if there were more training courses available online. We are now able to quickly find faults of our applications using predicates instead of reading through thousands of code lines looking at all possible conditions.
