Data Structures

[ #1546 ]

I've written a couple of objects that model data structures that we use here. I was just explaining the inner workings of one of them to the woman who is taking over from me. I'd forgotten quite how baroque it was.

The object is a reference to a hash of hashes of hashes. In each of these bottom level hashes, one of the values is a reference to a hash of arrays.

I drew a picture, but I'm not sure to what extent it helped! It's the data structure from hell.

Of course, the object's methods hide you from all this complexity. They just work :)

  • Maybe I've got it all wrong, but this is the sort of thing XML helps with. At least I think so. Create an XML serialisation of your data structure. Then you can fiddle with it, and make a back-compat thaw routine for transition to a better structure.

    Sure, it often doesn't apply to your app, but I thought I'd bring it up.
