Questions around writing code and queries

SuperFiles seem to be an interesting concept and are supported by ECL. To gain a better understanding, does someone have a practical example of when these should be used?

One simple example:

I have an ECL file called 'weblogs' that I want to process all of the weblogs I have ever recieved. I upload all the logs I have so far in a logical file and create a superfile that 'points to' that logical file.

Now in my code I use the superfile - it all works using my uploaded weblogs. Then tomorrow we have some more weblogs - operations uploads the days worth of weblogs to a new logical file - updates the superfile to point to the original file AND the daily file.

My code still executes as before with no changes. Note - if I had used PERSIST technology then any persists that needed to would rebuild.
