Thanks to all for the comments on my post. I got some new ideas and tasks.

One part of my initial question is still not clear for me.

If caching information to get better performance is a good way why is doing this with Storable and DB a bad or at least not so good way?

I could do my routines on a daily basis, freeze the hashref, store it in a table and retrieve the hashrefs of one item by ID with only one request.

---------------------------
| my_cache_table          |
---------------------------
| ID (primary)            |
---------------------------
| hashref with prices     |
---------------------------
| mod_date of prices      |
---------------------------
| hashref with images     |
---------------------------
| mod_date of images      |
---------------------------
| hashref with other stuff|
---------------------------
| mod_date of other stuff |
---------------------------

I donīt want to appear stubborn but I like to comprehend things. Caching one or another way seems to be common practice the above mentioned way not at all.

Thanks for some more enlightment
