Links to Useful Data

Hi, I'm new on that forum so please forgive me if I have chosen wrong category to ask my question :)

Coming back to the point, as I mentioned in the title I am looking for some links to useful data, that illustrate the use of basic statistics method that can be searched by statistical techniques, do you may be know any?
I found on the Internet one database like that
DASL/ but unfortunately it seems to be empty.

If you don't have any data like this may be you can help me get some idea which data I can choose for ANOVA, OLS, Time Series Model and Count Data Models.

Any help will be appreciated,
thank you in advance :)
