( #3333=superdoc: print w/replies, xml ) Need Help??

My current approach is going off flat files, and I think I need just two asynchronous processes resulting in two flat files. The first process looks at the products and works out the distinct pairs (i.e., going from 2,000 distinct products to 2 million distinct pairs).

pair 1: apple orange pair 2: apple banana pair 3: apple grape pair 4: orange banana pair 5: orange grape pair 6: banana grape

The above flat file serves as the input to the second process which looks at the price and inventory for each product and pair to work out the stats. The end result of this second process is written into the final flat file.

My tryst with perl and programming in general is about 3 months. The approach I'm taking looks neat and simple from a solution perspective to me (coding it however "feels" a little different, but am keen to put in the effort to keep the coding also simple). My reluctance to use an rdbms is that I'd probably have to teach myself "the how-to" especially when things break and fall apart.

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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
