not having any experience with arduino itself, i can only assume that with a wifi connection one would be able to make requests to a website for that data for reading/writing purposes.
The Arduino itself cannot store a large amount of data over time. You can have it store required data on an SD card so it can do data logging.

For interfacing with a website, the same idea can be done, but it would have to access the site every x seconds/minutes that you are measuring the data (i.e. you might want to measure temperature or pH more than once an hour...I have mine set for every 5 minutes).
