( [id://3333]=superdoc: print w/replies, xml ) Need Help??

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

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
