Lesson Re-Learned

Two lessons relearned/reinforced.  One in the positive and one in the negative.

1.) When working in a strange codebase, make no assumptions about the way that it works internally.  I got burned a little bit yesterday because I had made a false assumption about the way the existing code performed the aggregation of financial numbers.  I should have done a little more research on the inner workings of the existing code.  No big deal because…

2.) All two dozen places that I used aggregated data used the same 3-4 classes.  One 20 minute coding change later and all of the numbers on my report suddenly look much better.

    This data aggregates, are they in the data, domain, or view layer? Hmmm.. Maybe all three?
